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.

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

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.)

shall be of copper or copper alloy and suitable for the
application. Terminals shall be designed and
proportioned so that a connection made will not slacken
off or overheat under normal conditions of use. Clamp
type terminals shall be designed so that the conductors
can be rigidly and effectively clamped between metal
surfaces. Clamping devices with screws, which screw
directly into conductors, shall not be used.
5.3.3 Stress on conductor terminals. Conductors shall
be so supported and connected that there will be no
undue mechanical stress on either the conductors or the
terminals to which they are connected.
5.4 EQUIPMENT PROTECTION.

located in a secure, fire-isolated area within the building.
The area shall be free of stored combustible material and
ignition sources, i.e., areas such as electrical switch
rooms, store rooms and similar, are not acceptable.
In existing buildings without fire compartments the main
equipment shall be located in an area presenting the least
risk to the continued operation of the equipment in an
emergency.
5.4.2 Distributed equipment. Equipment installed in
a fire compartment or evacuation zone, servicing other
than the installed fire compartment or evacuation zone,
is not acceptable, except where the distributed equipment
is installed in a fire compartment in accordance with the
requirements for main equipment.

from unauthorized persons by a locked door. The key
shall be identical with other keys required for access to
control and indication equipment as specified in
AS 2220.1.
Non-sealed batteries shall be located in a separate
enclosure sealed from other parts of the equipment. The
enclosure shall be protected against corrosion adequately
ventilated, and be of such a size as will permit easy
access for battery inspection and maintenance without
need to disconnect individual cells or batteries.
5.6 EMERGENCY NOTICES. Notices providing
instructions to be followed in case of emergency, shall
be positioned adjacent to each ECP and WIP.
NOTE: The text of the notice is not specified in this Standard as this
depends on the type of building, type of system, and evacuation
procedures.
