TPC2879-206 PSU PCB
PSU (+ -)
Monitored 29.5VDC input from power supply module.
28V/0V (+ -)
28V output, fused at 500mA.
CC (-IP)
Class Change switch (
–
ve)
inputs, which cause the common sounder outputs to operate.
Note:
Stage sounders will not be affected unless programmed to do so (see program details).
PUL (-IP)
Pulse switch (
–
ve) inputs, which cause the common sounder and loop sounders outputs to pulse.PBUS
(+ -)
Note:
Stage sounders will not be affected unless programmed to do so (see program details).
PBUS
Input for RS-485 Peripheral BUS (PBUS) circuit, for remote control call points. The PBUS circuit is not
intended for repeaters or networking.
SNDR 1 (+ -)/SNDR 2 (+ -)
Two 24VDC programmable and monitored sounder outputs, configurable as FARE and FFRE (Fire
and Fault routing).
•
They can be programmed to turn OFF or ON in Continuously mode or in Pulsing mode (1s ON
and 1s OFF).
•
The sounders can be configured to be non-silencing or silencing.
FAULT (C NC NO)
Common fault signal changeover relay contacts. Normally energised (failsafe) contacts, change over
when any fault is active on the panel or in the event of total power loss. Unfused, Max 3A at 30VDC.
FIRE (C NC NO)
Common alarm changeover relay contacts. Activate when an alarm condition (470R) exists on the input
or ZONE circuit. Unfused, Max 3A at 30VDC.
