manually. On the PA0766 model Alert and Evacuate voice messages are automatically inserted in the Alert and Evac 
tone sequences respectively. Messages shorter than 0.5 seconds are not inserted. 
 
Generally the AIE- is left open (Auto) and operation of the T-GEN is controlled via the ALM- input from the fire panel.  A 
switch for the Isolate and Evacuation positions should be fitted only when there is no other warning system isolation 
facility (e.g., on older AS1603.4 panels).  For this arrangement, consideration should be given to indicating the isolate 
position via a hard-wired yellow LED or fault condition on the fire panel (see Section 3.1). 
   
If the 100V line is over-loaded (e.g. short circuit), T-GEN will shut down its amplifier output until the fault is removed. 
 
A test mode is provided for testing the 100V line and speakers. To activate this put T-GEN in Auto and fit the Test Link 
(LK4). T-GEN will produce a short 500Hz tone burst every 4 seconds at low volume (-30dB).  (Excludes Wail and Hee 
Haw for PA0766 and AS2220 for PA0886). 
 
PA0886 may be used for voice only applications (disable tone generation).  Operating the ALM- input will activate the 
alert message, operating the A/I/E- input will activate the evacuate message. 

 
Slave Mode 

In slave mode T-GEN does not produce its own tones but connects to a Master T-GEN via the SIG terminals. When 
connecting T-GENs together there must be only one Master T-GEN. Note that only the Master generates the tones and 
background music, and is connected to the panel Alarm output and Auto/Isol/Evac switch.  All slaves (max 20) and the 
Master T-GEN must be co-located and share the same 0V. 

 

Fault Monitoring  

If Alarm input fault supervision is enabled, then an open circuit on the ALM- input will cause a fault condition. Detection 
of an open or short circuit on the 100V line output (Master or Slave mode) or the SIG input (Slave mode only)  will also 
cause a fault condition. A fault condition will turn on the Fault LED and depending on Link 7 activate the Fault Relay or 
the DEF- output.  Note that the 100V line is not supervised for the first 60 seconds after power up to allow the monitoring 
capacitors to charge up. 
 
Note that the fault output is disabled when the T-

GEN is in “Isol”.

 

 

Public Address  

The operator may use the PA microphone (part number ME0290) for emergency public address. This is activated when 

the microphone’s PTT button is pressed while the A/I/E switch is in the Auto or Evac position. Public address overrides 

Alert and Evac tones. 
 
A remote microphone can be connected to the T-GEN for general paging by using the PA0688 microphone preamp.  
Details are contained in the PA0688 Microphone Pre-Amplifier Module User Manual (LT0371). 
 

Evacuation Messages 

The four messages are defined as Msg1, Msg2, Alert and ISO8201 keywords. Refer to the table for the actual pre-
recorded phrases. PA0766 will play the alert message during alert, Msg1 (or Msg1 + Msg2 if recording is longer than 4 
seconds) during AS2220 or ISO8201 Evac if SW8 is off, Msg2 during AS2220 if SW8 is on, and just the ISO8201 
keywords during ISO8201 if SW8 is on. 
 
PA0886 will play a bell sound instead of the Alert tone and alert message. It will play Msg1 (or Msg1 + Msg2 if recording 
is longer than 4 seconds) during AS2220 Evac (SW6 and SW8 OFF) if LK4 is OFF and just Msg2 if LK4 is ON (TEST 
Mode is not available in AS2220 Mode). In ISO8201, Msg1 (or Msg1 + Msg2 if recording is longer than 4 seconds) will 
be played back after the second keyword. If no Evac message is present, PA0886 will play ISO8201 with keywords only. 
 

Recording Messages  

The T-GEN supports 2 recordable messages, Alert and Evac. Alert can be up to 4 seconds duration. Evac consists of 
two factory-programmed messages (Msg1 and Msg2) that can be up to 7.2 seconds in total length.  The Alert and Evac 
messages can be re-recorded using an ME0290 PA microphone.  
 
To record a message use the following steps (when T-GEN is not in alarm or evacuate or test mode): 
 
1. 

Fit link  LK3 - REC EN on the PCB. This enables the recording and playback of messages. 

2. 

Select the message to be recorded (played) using switch 2 - T1 as follows: 

 

T1 Off  - Evac message   

T1 On   - Alert message 

3. 

Press the microphone button to start recording. Recording will continue until either the button is released or the 
maximum message length has been reached. (See NOTE). 

4. 

The recorded message can be played back using the Play button. Note that if the A/I/E switch is not in the 
Isolate position the played back message will be broadcast over the speaker system. Recording is not 
broadcast. 

5. 

When recording has been completed, re-set T1 to its original position and remove Link LK3 to disable the 
record function. 

 

NOTE:  Messages less than 0.5 seconds will not be broadcast (this can be used to delete an unwanted message). Note 

that if Evac Msg1 is replaced with a message of more than 4 seconds duration, Evac Msg2 will also be 
overwritten.
