2.3 System Overview
The Ampac EV3000 Occupant Warning and Intercommunication System is a microprocessor based
OWIS system that complies with Australian Standards AS2220.1 and produces Alert and Evacuation
signals compliant with AS1670.4
The OWIS comprises of two sub-systems,
1. Occupant Warning System (OWS)
The prime function of an OWS is to transmit via speakers in evacuation zones, alert signals,
evacuation signals and public address clearly and reliably.
The OWS can automatically initiate evacuation procedures or be manually operated as well
being used for non-emergency functions, e.g. background music and general PA facilities.
2. Occupant Intercommunication System (OIS).
The OIS is a totally independent intercommunication system provided to communicate on a
one to one basis from the Master Emergency Control Panel (MECP) to the individual Warden
Intercommunication Points (WIP’s) within the evacuation zones.
The OWS and OIS are collectively referred to as the Occupant Warning and Intercommunication
System (OWIS).

12 Appendix E Maintenance Logs
12.1 E1 Monthly Test Log Book
To complete the Monthly Test Log follow the procedure below.
1. Visually inspect the installation for damage, eg. all speakers, warden intercom points, visual
alarms, control panels etc.
2. Make an announcement to all occupants that the Emergency Warning System is to be
tested. This is done by selecting the 'Auto, Manual, Isolate' keyswitch to 'Manual", selecting
the 'All Call' All PA button, pressing the PTT button on the microphone and then speaking
into the microphone. At the end of the announcement select 'All Call' All Off and return the
keyswitch to the 'Auto' position
3. Isolate the Brigade calling interface at the Fire Indication Panel, then simulate an alarm at
the Fire Indicator Panel. An alert tone will sound; check that the alert indicator is illuminated
for that zone at each ECP and the buzzer is on.
4. To reset the system, reset the FIP then turn the ECP Auto, Manual, Isolate keyswitch to
Manual press the buzzer mute switch, followed by the Master Reset switch.
5. With the keyswitch in the Manual position select P.A. for the first zone and make an
announcement, then select Alert, then Evac and finally cancel, (Ref Fig 2 Page 8 EWS
Control Panel) verify that the announcement and tones were audible and correct. Repeat
this procedure for each zone and for each Emergency Control Panel. Make sure that when
each Emergency Control Panel is tested its keyswitch is returned to 'Auto'.
6. Test the operation of the Emergency Intercommunication System at each Emergency
Control Panel using the following guidelines.
Warden Intercom Point Calling Emergency Control Panel
The following is the procedure when initiating a call from a WIP to the ECP:
1. Remove the handset from the cradle at the WIP. This will cause the appropriate WIP call
indicator to flash at all ECP's and the WIP call buzzer to sound at all ECP's
2. A confidence tone can be heard at the WIP
3. The ECP which responds to the call is referred to as the controlling ECP. The call is
answered at the ECP by removing the handset from the cradle and pressing the WIP call
switch which corresponds to that WIP.
Completing The Call By The Warden Intercom Point
If the WIP handset is placed back onto its cradle after the call is connected, the handset at the
controlling ECP will go silent and WIP call indicator will switch off, completing the call.
Emergency Control Panel Calling Warden Intercom Point
The following is the procedure when initiating a call from the ECP to a WIP:
1. The confidence tone can be heard in the handset at the controlling ECP
2. The WIP call switch corresponding to the WIP to be called is pressed, this causes the WIP
call indicator at the ECP's to flash, and the buzzer to sound at the WIP. Up to 5 WIP's can
be called using this procedure
3. When the handset is picked up at the WIP the connection is established and the WIP select
indicator becomes steady
4. If the ECP is calling more than one WIP, the status of the calls, ie. WIP answering is
reflected in the WIP select indicators
Completing The Call By The Emergency Control Panel
The call can be completed at the ECP in two ways. By placing the handset on the cradle, which will
cause the earpiece at the WIP to go silent, i.e. no confidence tone, OR by pressing the WIP call
switch which will also cause the earpiece at the WIP to go silent, i.e. no confidence tone. In both
cases the handset at the WIP must be replaced on the cradle and then removed to reinstate the
confidence tone in the WIP earpiece.

16
EV3000 COMMISSIONING LOG BOOK
Final Checks
1. Press the Lamp Test switch at each Emergency Control Panel (Ref Fig 1
Page 7 Master Control Panel Layout). For a period of 6 seconds the buzzer will sound
intermittently and all indicators will illuminate and flash, except system on batteries, charger
fault, battery fault, battery isolate and power on.
2. Check each Emergency Control Panel that the keyswitch is in 'Auto' and all other switches
are off.
3. Check the electrolyte level of the batteries if applicable.
4. Check the batteries for any damage.
5. Record all faults and relevant comments in the space provided.
6. Date and sign the report.
7. Contact the service agents if any faults need to be attended to.

12.3 E3 Battery Capacity Test
This test may be performed away from the system.
Disconnect the system batteries and replace with substitute batteries.
Discharge the system batteries at current of Idis , the formulae for the calculation of Idis can be
found in section 6 ( record the value in section 6 ).
Measure the voltage across the battery terminals. Discharge the batteries until the voltage across
them reaches the discharged terminal voltage obtained from the battery manufacturer (this should
also be recorded in Section 6) Record the time taken to reach this voltage in the log book. If the time
taken is less than 30 mins take any necessary corrective action.
Recharge the system batteries to a capacity greater than 95% of maximum using a battery charger,
the system should not be used to achieve this.
Remove substitute batteries from the system and replace with the system batteries.
