Nittan OCM-AS3 Installation & Technical Manual

RELAY OUTPUT MODULE OCM-AS3
INTRODUCTION
DESCRIPTION
The OCM-AS3 forms part of the Nittan (UK)'s
SENSORTEC-ANALOGUE range of Analogue
Addressable Devices.
This module is designed to perform a loop powered,
control relay output function from the detection signal-
ling loop of an analogue-addressable fire detection
system.
The OCM-AS3 may be used for a variety of purposes
such as closing fire doors, shutting down plant machin-
ery and operating smoke extraction systems via this
loop powered device.
OPERATION
The fire alarm control equipment must be capable of
communicating with the OCM-AS3 relay output control
module. If in doubt, check with panel manufacturer.
The OCM-AS3 is a loop powered, two-wire signalling de-
vice, it is connected onto the detection signalling loop's
SIG+ and -S wires, exactly as any other 'AS' sensor or
device.
FEATURES
* A relay control output for the switching of external
equipment such as fire doors etc..
* Loop powered, no PSU requirements
OCM-AS3 Relay Output Contol Module
is made up as follows:-
1 x Metal enclosure c/w 20mm knockouts
1 x OCM-AS3 PCB c/w internal plastic PCB enclosure
with hinged lid.
1 x Earth point (on lid)
1 x Earth point (inside of enclosure)
1 x 200mm Earth Strap
1 x Label inside lid for product identification and
