An emergency warning and intercommunication system is installed in a building for the
purpose of enabling the orderly evacuation of the building in the event of an emergency. To
achieve this aim, it is essential that the emergency warning and intercommunication system
has the following capabilities as appropriate:

(a) Provision for manual and automatic activation.
(b) On activation, the ability to alert wardens with an audible alarm. (A visual alarm may
also be required).
(c) Where both an emergency warning system and an emergency intercommunication
system are required to comply with AS 2220, these systems are integrated to provide
a positive means of intercommunication between the House Warden and the various
floors or Zone Wardens to enable the orderly evacuation of the building.
(d) Emission of audible or visible signals or both that will either (i) alert the occupants; or
(ii) order the occupants to vacate the building.
(e) Ease of operation.
(f) Continuous operation under conditions of hazards.

SECTION 2. EMERGENCY WARNING SYSTEMS
2.1 GENERAL REQUIREMENTS.
2.1.1 Emergency control panels (ECPs).
2.1.1.1 Location. The master emergency control panel
(MECP) and any additional emergency control panels
(ECPs), that may be required, shall be installed in an

approved location complying with the following
requirements:
(a) The ECP area shall be secure and relatively isolated
acoustically. The ambient noise level at the ECPs
shall not exceed 70 dB(A).
NOTE: This Standard expects the ambient noise level to be
assessed taking into consideration the unusual circumstances of
an emergency. For example, during a fire, it is expected that a
fire brigade booster pump may be operating outside the building,
thereby increasing the noise level in the lobby area above 70
dB(A). The lobby area in this case, would be unsuitable for the
ECP, unless provisions are made for its isolation.

Licensed to LUU MINH LUAN on 25 Feb 2002. Single user licence only. Storage, distribution or use on network prohibited.

(b) Access to the ECPs shall not be obstructed, nor
shall any ECP obstruct the evacuation of the
building.
NOTES:
1. It is not recommended to locate any ECP in an area where
a high level of activity is expected during an emergency
evacuation.
2. In the event of an emergency, operators of the system, and
most particularly the house warden are expected to make a
series of decisions over a short time. It has been established
that a suitable environment, as well as a system that is easy
to operate, play an important role in the successful handling
of the emergency, and hence, the safety of occupants.
3. Safe manning should be possible under anticipated
conditions of hazard and emergency.

(c) ECPs shall be located so that visible indications
shall remain readily distinguishable, under all
ambient lighting conditions.
2.1.1.2 Physical working environment. The following
requirements shall apply:
(a) Lighting. Emergency lighting shall be provided as
required in accordance with AS 2293.1
(b) Ventilation. When batteries are located inside the
ECP cubicle, adequate ventilation in accordance
with AS 2676 shall be provided.
(c) Workspace. The personnel workspace shall be
arranged so as to minimize distraction by peripheral
activities, and its plan dimensions shall be not less
than those specified in Figure 2.1.

2.1.2 Additional facilities. A notice shall be provided
at every ECP location, giving essential instructions
necessary to ensure the correct use of the equipment, the
terminology being understandable by non-technical
personnel.
NOTE: It is recommended that a telephone be provided in the
vicinity of the MECP.

2.1.3 Interconnection of alarm systems. The main
equipment shall be interconnected with the fire indicator
panel (FIP) where provided. An isolation facility shall be
incorporated, to prevent automatic actuation of the
emergency warning system under test conditions. Any
other alarm system connected to the emergency warning

system shall have a similar facility.
Isolation of alarm-initiating signalling lines shall raise a
fault indication as specified in AS 2220.1.
2.2 FUNCTIONAL REQUIREMENTS.
2.2.1 Generation of audible signals. The audible
signal pattern shall comply with AS 2220.1.
2.2.2 Distribution of audible signals. The audible
warning signals shall be distributed throughout the
appropriate evacuation zone by a system of
loud-speakers.
NOTES:
1. It is recommended that at least one power amplifier per
evacuation zone be provided.
2. Consideration is recommended to the distribution of warning
signals through induction loop systems for those with impaired
hearing. (See AS 1088.4.)

2.2.3 Output of loudspeakers. At any location within
the signal reception area, the A-weighted sound pressure
level of the audible signals, measured with the time
weighting ‘F’ (fast), shall exceed by a minimum of 10
dB the noisiest background sound pressure level
averaged over a period of 60 s. This level shall be not
less than 65 dB and not more than 105 dB. These values
are to be determined in accordance with AS 1259.
For audible signals intended to arouse sleeping
occupants, the sound pressure level signals shall be not
less than 75 dB when measured at the sleeping position
(see Note).
The sound pressure level shall not fall by more than 6

dB when tested under battery-powered operation (see
Clause 4.3.2).

Loudspeakers installed within the vicinity of any ECP or
WIP shall not inhibit the normal operation of the system.

Both red and white devices shall not be present within
the same evacuation zone.

NOTE: The 75 dB signal level may not be adequate to wake all
sleeping occupants.

NOTE: The regulatory authority may have specific requirements
which could limit the number of alarm initiating devices which can
be installed within one evacuation zone.

2.2.4
Visible signals.
Where the background
A-weighted noise level exceeds 95 dB, visible signals
shall be installed. The number and disposition of visible

signalling devices, shall be such as to ensure visibility in
the required areas, and the intensity of the visible signals
shall ensure perception by the occupants. They shall
comply with the requirements for visible signals in AS
2220.1.
Visible signalling devices shall be provided with suitable
identification, e.g. signs or symbols giving the
appropriate instructions.

AS 2220.2—1989

2.3 OPERATIONAL REQUIREMENTS.
2.3.1 Initiation. In addition to manual operation from
an ECP and any automatic activation, provision shall be
made to manually actuate the EWS from within each
evacuation zone. This shall be achieved by either (a) one or more red manual call points, complying with
AS 1603.5, as part of the fire alarm system; or
(b) one or more white emergency alarm initiating
devices, complying with AS 2220.1.

2.3.2 Duration of alert signal. The alert signal shall
continue on until manual control of the system is taken
or, if not responded to within a prescribed time from
initiation, the signal shall be automatically replaced by an
evacuation signal. The prescribed time shall be
established to suit the particular building but it shall not
exceed 10 min. For buildings with 6 or more evacuation
zones, the automatic execution of the evacuation shall be

arranged, so that the affected evacuation zones are
evacuated first and the other evacuation zones are
evacuated in a logical order of priority.
2.3.3 Use of the system for non-emergency purposes.
The emergency warning system may be used as a
paging-background music system under non-emergency
conditions, provided that (a) the equipment is designed to override ancilliary
functions under emergency conditions as specified
in AS 2220.1;
(b) the capacity of the battery charger as specified in
AS 2220.1 will provide sufficient current to
accommodate the additional load; and
(c) the system integrity is maintained.

SECTION 3. EMERGENCY INTERCOMMUNICATION SYSTEM
3.1
SE P ARAT ION.
T he emergency
intercommunication system shall be separate from the
Telecom Australia system and from any other
communication system.
3.2
LOCATION OF WARDEN INTERCOMMUNICATION POINT (WIP). A WIP shall be

located on each level, or, where a floor is divided into
two or more evacuation zones, in each evacuation zone.
The requirements for the position of each point are
similar to those given in Clause 2.1.1.1 for the ECP,
with the additional requirements that it

shall be convenient to a fire-isolated escape route, or
means of egress, and in a position in the level or
evacuation zone, that will permit control of and egress
from the associated area.
If the WIP handset is enclosed within any other cabinet,
it must be assured that the 80 db(A), audible signal,
when measured at 1 m from the apparatus is maintained
as specified in AS 2220.1.
WIPs shall be mounted at a height between 1200 mm
and 1800 mm above floor level.

SECTION 4. POWER SUPPLY
4.1 GENERAL. The system shall be energized from a
reliable source of supply and shall be connected in
accordance with AS 3000. The power source shall be—
(a) an a.c. supply from an electricity authority or a
source equal in quality and reliability; and
(b) batteries, as specified in Clause 4.3, which shall
supply the necessary power to the system in the
event of mains input power failure.
4.2 POWER SUPPLY CONNECTION. The system
shall be directly connected to the line side of the nearest

electrical distribution board and it shall be separately
protected by a circuit breaker or fuse. The circuit breaker
or fuse shall be clearly labelled, to indicate that it
con t r ol s th e emer gen cy war n in g ( and
intercommunication) system. No other load or equipment
shall be connected to the circuit.
4.3 BATTERIES.
4.3.1 General. Batteries shall be of a type specially
designed for continuous float charging conditions, and
shall comply with the performance requirements of one
or more of the following, as appropriate:
(a) Lead-acid pasted type batteries (see AS 1981).
(b) Lead-acid Plante positive plate type batteries (see
AS 2191).
(c) Sealed batteries (see Appendix C).
Sealed batteries which cannot be recharged after a total
discharge to zero volts are not acceptable.
Cells which require the addition of electrolyte during
service shall be provided with means of visual inspection
of the electrolyte for maximum and minimum levels, and
low electrolyte alarm indication.

NOTES:
1. Batteries which have a memory effect or cyclic discharge/charge
requirements are considered unsuitable.
2. For requirements on the installation, of batteries, see Section 5.

4.3.2 Battery capacity. The capacity of the batteries
shall be, in the event of mains input power failure,
capable of maintaining the system in normal working

(quiescent) condition for at least 8 h. After which,
sufficient capacity shall remain to operate the emergency
warning and intercommunication system including all
audible and visible signals at the specified outputs, for a
period not less than 90 min and within the temperature
range specified in AS 2220.1.
NOTE: When calculating the capacity of the battery required to
power the system, consideration needs to be given to:
(a)
The available capacity of the battery at the beginning and at
its end of life.
(b)
The reduction in capacity due to low ambient temperature.
(c)
The reduction in capacity when discharging at the 1.5-hour
rate compared to the 10-hour rate.

The above considerations will lead to a required capacity
of between 1.5 and 2 times the capacity at the 10-hour
rate.
4.3.3 Battery connections. The connecting leads to the
battery shall be clearly labelled to reduce the possibility
of reverse connections to the battery.
Two types of external connections are acceptable:
(a) Bolted lugs for centrally located battery supplies; or
(b) Quick connector type connectors for distributed
battery supply.
(See also AS 2220.1 for requirements for
battery protection.)

APPENDIX B

TYPICAL METHOD OF OPERATION AND RESPONSE OF PERSONNEL
(This Appendix does not form an integral part of this Standard)
B1
GENERAL.
The method of operation of the emergency warning and
intercommunication system and the response of personnel may vary according to the nature
of the establishment.
A plan should be drawn up to allow for normal occupancy, (i.e. during hours prescribed in
fire or emergency orders for the building), and for alternative action during other hours.
B2 TYPICAL PLAN.
B2.1 Normal occupancy.
(a) Initiation. Initiation should be as follows:
(i)
In the event of an alarm originating from the fire alarm system or other
emergency alarm system in the building, the emergency warning system
should automatically actuate the alert signal mode on the ground floor (or
other floor as appropriate to alert the house warden or a deputy on duty) and
on the appropriate floors to alert the zone wardens.

Licensed to LUU MINH LUAN on 25 Feb 2002. Single user licence only. Storage, distribution or use on network prohibited.

NOTE: The ‘appropriate’ floor(s) would be determined from the size, nature and occupancy of
the building and could comprise only that floor from which the alarm originated, or a
predetermined group of floors of which the floor in alarm is a member, or all floors (the latter
is recommended).

(ii)

In the event of an alarm being received by the house warden (e.g. by
telephone or messenger) the house warden should arrange for the actuation of

the alert signal on appropriate floors.
(b) On hearing the alert signal, all zone wardens on the signalled evacuation zones should
report to their respective WIPs. On arrival at their respective WIPs, zone wardens
should immediately call the controlling ECP (to indicate that they have responded).
(c) Other occupants of the building, although alerted by the signal, should continue normal
duty or commence to take actions prescribed by fire or emergency orders.
(d) On arrival at the ECP, the house warden should ascertain the alarm-originating floors
from the FIP and obtain reports from the zone warden from the alarm-originating floor
(and perhaps some other floors).
NOTE: A predetermined period should elapse before manual switching-off of the alert signal by the house
warden.

(e) On receipt of information from the floor in alarm, the house warden should assess the
situation, call the appropriate emergency service and decide whether automatic
evacuation should continue or the system be placed under manual control.
(f) If communication with wardens in evacuation zones other than those previously alerted
is necessary, the house warden may sound the alert signal in the appropriate evacuation
zones or use the emergency communication system to summon the zone wardens to
their stations.
(g) When under manual control, the evacuation of an evacuation zone or zones is
necessary, the house warden should issue the appropriate orders or sound the
evacuation signal, or both.
(h) All zone wardens should stand by until dismissed by the house warden.
(i) The house warden should be ready to assist the fire brigade or other emergency service
responding to the emergency conditions.
B2.2 Out-of-normal hours. The sounding of the alert signal outside of the prescribed
hours for normal occupancy, is an indication to any occupant that action should be taken
as prescribed in fire orders, and if no action is required, the occupant should leave the
building.
