PA0766 PCB Assy,1955-1-3,T-GEN,Tones,Flt Mon, PA Speech
Standard model of T-GEN with SF0341 speech IC pre-recorded messages for Australia and New Zealand.
PA0886 PCB Assy, 1955-1-3, T-GEN, NZ Bells and Speech, Flt Mon, PA
Similar to PA0766, but has SF0342 speech IC with a bell sound recorded instead of the alert message and has different
software to support playing the messages only (no tones). Hee-Haw tone is not supported, and the Wail and RH3 tones
cannot have the Evacuate message inserted.
FP0698 FP, T-GEN, 3U Rack Mtg Panel, C/W PCB & Mic
A 3U 19” rack mounting module complete with a PA0766 T
-GEN 50 mounted on the back of it. A microphone and front
panel label are supplied fitted to provide a complete functional unit. A loom for power, control and monitoring is factory
fitted. The loom is connectorised for direct use with
MX1
. The connector can be removed and the loom wired into other
panels if required. An Auto/Isolate/Evacuate keyswitch is included loose for fitting if required. Wiring to the 100V
speaker line is also required to make it operational.
ME0289 Mech Assy, 1955-16, T-GEN, 1U Rack Mtg, A/I/E Control Panel
A 1U 19” rack mounting module that has a 3 way rotary switch and Auto/Isolate/ Evacuate label on it, wired so that it can
be connected to T-GEN. No T-GEN is included.
ME0290 Mech Assy, 1955-3, T-GEN/MVAC Dynamic Microphone
ME0490 Mech Assy, 1955-44, T-GEN 50, Dynamic Microphone
A noise-cancelling dynamic microphone suitable for plugging onto the T-GEN to provide emergency PA or for field
recording of the digitised speech message(s). ME0290 has a 1m coiled cord. ME0490 has a 1m extension to this coiled
cord, suitable for internal routing in the cabinet, if required.
ME0291 Mech Assy, 1955-24, T-GEN A/I/E Switch Kit
A small metal bracket containing a 3 position rotary switch, labelled and wired for connection to the T-GEN A/I/E- input.
This allows control of T-
GEN’s operation through selection of the Auto, Isolate and Evacuate positions. The bracket can
be mounted in most fire alarm panels.
ME0292 Mech Assy, 1955-25, T-GEN Empty Box, Keyed 003
A 240W x 295H x 85D, cream wrinkle coloured, locked, metal box suitable for mounting the T-GEN (not included) inside.
A standalone tone generator and PA announcement system can be constructed by using the T-GEN mounted in a
cabinet (e.g., ME0292), together with the ME0291 Auto/Isolate/Evacuate switch, and the ME0290 microphone. A
suitable power supply is also required, (e.g. Series 1948 24V 2A (FP0766) and 2 x 6.5Ah hour batteries - this is the
same size as the T-GEN box).
