Model GCM-8
Graphics Control Module
Installation Instructions
INTRODUCTION The Model GCM-8 Graphics Control Module from
Siemens Industry, Inc. is a remotely located module. It
provides twenty-four outputs to drive eight pairs of
LEDs. Each pair contains one bicolor (red/green) and
one yellow LED. It also provides eight inputs to connect
to external momentary switches. The functions of the
switches and LEDs are programmed by inserting an
SCM-8 in the Zeus Tool (Refer to the Zeus Quick Start
Guide, P/N 315-033875). All LEDs can be programmed
ON, OFF or FLASHING.
The GCM-8 is used for manual control of the fire
system.
There is an additional input for a momentary lamp test.
OPERATION The GCM-8 interfaces to eight switches and eight pairs
of LEDs. Each switch is associated with a pair of LEDs.
Pressing any of the eight switches generates a unique
CAN message on the bus to the NIC-C or DAC-NET that
indicates which switch was pressed. A CAN message
from the NIC-C or DAC-NET to the GCM-8 produces a
preprogrammed output to the corresponding LED (ON,
FLASHING or OFF). An open collector is provided for
connection to the CAN Sounder Board (CSB), a separate
audio module. The CSB provides an audible feedback to
indicate that the switch closed properly and that
communication between the GCM-8 and NIC-C or
DAC-NET was successful. Refer to the CSB Installation
Instructions, P/N 315-033040, for more information.
By shorting terminals 1 and 2 of TB1, all LEDs will turn
on to confirm that they are working and automatically
will return to their normal state after a few seconds. The
lamp test switch on multiple GCM-8s can be connected
to a single switch.
