NAM-AS3 LOOP POWERED
INPUT MODULE
INSTALLATION & TECHNICAL
MANUAL
INTRODUCTION
DESCRIPTION
The NAM-AS3 forms part of the Nittan (UK)'s
SENSORTEC-ANALOGUE range of Analogue
Addressable Devices.
This module is designed to perform a loop powered,
addressable input module function from the detection
signalling loop of an analogue-addressable fire detec-
tion system.
The NAM-AS3 may be used for a variety of purposes
such as monitoring a 'relay contact input' or monitor the
operation of a 'sprinkler flow monitoring switch'.
OPERATION
The fire alarm control equipment must be capable of
communicating with the NAM-AS3 input module. If in
doubt, check with panel manufacturer.
The NAM-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
* Monitoring a relay contact input.
* Monitoring the operation of a sprinkler flow switch.
NAM-AS3 Input Module is made up as
follows:-
1 x Metal enclosure c/w 20mm knockouts
1 x NAM-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
device address identification.
