Technical
Specifications
SCR25A
The call-in module shall be a Bogen Model SCR25A,
or approved equivalent, and shall operate with room
selector panels in Bogen Multi-Graphic systems.The
module shall provide annunciator latching capacity
for up to 25 circuits.
The module shall provide 25 silicon controlled recti-
fiers and shall permit the use of momentary switch-
es without SCRs for call-in to a central console.
Connection to the room selector panel shall be via
simple plug-in method. Support brackets shall be sup-
plied. Termination shall be via centerline pins. The
module shall measure 16-
3
/4" W x
3
/4" H x 3-
1
/2" D, and
shall weigh 8 ounces.
TZMA
The Time Zone Module shall be a Bogen Model
TZMA, or approved equivalent, and shall operate
with room selector panels in Bogen Multi-Graphic
systems.The unit shall provide six (6) zones of time
signaling. Assignment of any circuit to any zone shall
be via DIP switches located on the module.
Relays shall be ultra-reliable and designed to provide
over 1,000,000 operations. Each relay shall be sealed
to be impervious to failure caused by contact conta-
mination.
The module shall draw power for operation from the
Bogen Model PRS312 Power Supply. Tones shall be
generated by the Bogen Model TG4C Tone
Generator Module. Tones shall be distributed to
zones via a Bogen booster amplifier.
The module shall connect to the room selector panel
with a simple plug-in method. Support brackets shall
be supplied. Termination shall be via centerline pins.
The module shall measure 16-
