2W-MOD2
2-wire loop test/maintenance module
for 2-wire i3 series standard, sounder,
and Form C relay models
(Replaces Model No. 2W-MOD)
Product Overview
Allows all 2-wire i3™ detectors to be
used on any compatible 2- or 4-wire fire
alarm control panel
Interprets the i3 remote maintenance
signal
Provides visual indication and an out-
put relay when a detector on the loop
requires cleaning
Initiates the EZ Walk loop test
Provides Style D wiring on IDC loops
Green, red, and yellow LEDs indicate
– Loop communication status
– Maintenance alert
– Freeze trouble
– Alarm
– EZ Walk test enabled
– Wiring fault
System Sensor’s 2W-MOD2 two-wire loop test/maintenance module maximizes the
benefits of the i3™ series smoke detectors, by offering detector remote mainte-
nance signaling and EZ Walk loop testing capabilities.
Installation ease. The 2W-MOD2 mounts to a 4″-square back box for quick and
easy installation. Terminal blocks with durable SEMS screws assure a reliable
connection.
Intelligence. The 2W-MOD2 allows communication to 2-wire i3 detectors with
any listed fire alarm control panel. This in turn enables i3 detectors to initiate
a remote maintenance signal when they are in need of cleaning, and to provide
a visual indication of this condition at the module and at the panel. The 2W-
MOD2 also features the EZ Walk loop test for 2-wire i3 series detectors. This
function verifies the entire initiating loop wiring with just the press of a button.
Instant inspection. The 2W-MOD2 includes three LEDs — green, red, and
yellow — that provide status indication for the loop. These LEDs indicate the
following:
– Loop communication status
– Maintenance alert
– Alarm
– Freeze trouble
– EZ Walk test enabled
– Wiring fault
