Installation Instructions
Model OCM-16

Output Control Module

INTRODUCTION The SIEMENS Model OCM-16 Output Control Module

is a remotely located, general purpose output module. It
provides sixteen open collector outputs to drive LEDs,
incandescent lamps, or external relays. There is an
additional output for a local audible and two inputs for
momentary lamp test and local audible silence switches.

OPERATION The OCM-16 is mounted in an enclosure that is re-

motely located from the Main Panel. Communication
between the OCM and the NIC-C is through the Control
Area Network (CAN) bus. Each OCM-16 has two 10
position rotary switches that are used to set the board
address on the CAN which is a sub-address of the
NIC-C. The 16 outputs of the OCM-16 are controlled by
messages received from the NIC-C over the CAN.

A CAN message can activate any or all of the 16 outputs
to drive LEDs, incandescent 24 Volt lamps or relays.

Whenever any of the outputs is activated, (LEDs, lamps
or relays ON) the local audible (if installed) will sound
until it is acknowledged by shorting position 19 and 20
on TB2. If the outputs are deactivated before the alarm
(local audible) is acknowledged, the alarm (local
audible) will cease to sound.

By shorting terminals 17 and 18, all LEDs or lamps will
turn on to confirm that they are working and automati­cally will return to their normal state after a few sec­onds. Both the lamp test and local audible silence
switch on multiple OCM-16s can be connected to a
single switch, one for each function. A single audible
can also be used with multiple OCM-16s.

PRE-INSTALLATION Rotary Address Switches - Set the board address for each OCM-16 using both of

the ten-position rotary switches located on the board (See Figure 2). Each of these
addresses must be a sub-address of the NIC-C and must be the same as the ad­dresses assigned in the Zeus Programming Tool.

S1/S2 LED, Incandescent/Relay Select Switches

 When LEDs are used, open corresponding dipswitches on S1 and S2 (Refer

to OCM-16 Switches Table) to provide a current limiting resistor of 2.7K
ohms to each LED.

 When incandescent lamps or relays are used, close corresponding

dipswitches on S1 and S2 (Refer to OCM-16 Switches Table) to bypass the
limiting resistors.

INSTALLATION An OCM-16 may be installed in a REMBOX. When using REMBOX 2 or 4, mount the

OCM-16 in one module space on a REMBOX2-MP, P/N 500-634211 or REMBOX4-MP,
P/N 500-634212 using the four screws provided. (Refer to REMBOX2-MP/REMBOX4­MP Installation Instructions, P/N 315-034211.) Up to 4 OCM-16s will fit in a
REMBOX2; up to 8 OCM-16s will fit in a REMBOX4.

WIRING

Disconnect BATTERY and AC prior to working on equipment.

 Each OCM-16 module is a node in the CAN bus.

 The OCM-16 can be installed with or without an RNI. Connect 24V and

CAN bus as shown in Figures 2 and 3.

 Up to 99 CAN modules, in any combination, can be connected to the CAN

bus of each NIC-C.

 Each OCM-16 module is shipped with one CCS cable.

 Cable connections for OCM-16 modules are shown in the following table:
