T-GEN 50
24V Alert & Evacuate Tone Generator
INSTALLATION AND OPERATING INSTRUCTIONS
The VIGILANT T-GEN 50 is a self-contained AS 2220 and ISO 8201 Alert and Evacuate tone generator, with speaker
line supervision and speech. It has been designed to connect directly to fire alarm panels, but may be connected to other
suitable digitised equipment.
T-GEN 50 is available in 2 versions (see page 8 for a full list of available items and accessories):
PA0766
Tones, fault supervision and speech. Contains (SF0341)
–
Speech IC with 4 pre-recorded messages
that are inserted into the Alert and Evacuate tones. A microphone input is also provided for
emergency public address and for recording messages different to the standard messages supplied.
A suitable microphone is Part Number ME0290.
PA0886
Same as PA0766 except fitted with SF0309 software and SF0342 speech IC in which the alert
message is a recorded bell sound. Alert and evacuate tones may separately be disabled so only the
recorded messages are played. DIP switches 5-8 select different functions.

OPERATION
Operation of T-GEN is controlled by the Auto/Isol/Evac (AIE-
) input. In the “Auto” position the Alar
m input (ALM-) is
enabled. In the “Isol” (Isolate) position the Alarm input is disabled and any latched fault or alarm conditions are reset. In
the “Evac” position the Evacuate tone is generated.
In Auto mode activation of the Alarm input starts a six stage rising amplitude Alert tone. This continues until one of the
following occurs:
- the Alarm input returns to normal (Alarm input in non-latching mode), or
- the AIE- input is changed to Isol, or
- the AIE- input is changed to Evac, or
- the Alert to Evacuate change-over time is reached.
If the Alert to Evacuate change-over time is set to 0 sec, then no Alert tone is generated and the Evacuate tone is
generated immediately. If the change-over time is set to Alert only, no Evacuate tone is generated and must be initiated
