Model OCM-16

Output Control Module

Installation Instructions

INTRODUCTION The SIEMENS Model OCM-16 Output Control Module

is a re otely located, general purpose output odule. It

provides sixteen open collector outputs to drive LEDs,

incandescent la ps, or external relays. There is an

additional output for a local audible and two inputs for

o entary la p test and local audible silence switches.

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

otely located fro the Main Panel. Co unication

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

essages received fro the NIC-C over the CAN.

A CAN essage can activate any or all of the 16 outputs

to drive LEDs, incandescent 24 Volt la ps or relays.

Whenever any of the outputs is activated, (LEDs, la ps

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 alar

(local audible) is acknowledged, the alar (local

audible) will cease to sound.

By shorting ter inals 17 and 18, all LEDs or la ps will

turn on to confir that they are working and auto ati-

cally will return to their nor al state after a few sec-

onds. Both the la p test and local audible silence

switch on ultiple OCM-16s can be connected to a

single switch, one for each function. A single audible

can also be used with ultiple 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 ust be a sub-address of the NIC-C and ust be the sa e as the ad-

dresses assigned in the Zeus Progra ing 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 li iting resistor of 2.7K

oh s to each LED.

 When incandescent la ps or relays are used, close corresponding

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

li iting resistors.

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

OCM-16 in one odule 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/REMBOX4-

MP 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 odule 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 odules, in any co bination, can be connected to the CAN

bus of each NIC-C.

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

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