BEFORE INSTALLATION
This information is included as a quick reference installation guide. Refer to
the control panel installation manual for detailed system information. If the
module will be installed in an existing operational system, inform the operator
and local authority that the system will be temporarily out of service. Discon-
nect power to the control panel before installing the module.
Notice: This manual should be left with the owner/user of this equipment.
This product is intended for use in ordinary indoor locations.
GENERAL DESCRIPTION
The MOD2W allows a control panel to receive a “need for maintenance” sig-
nal from two–wire i
3 series smoke detectors, model numbers 2W–B, 2WT–B
and one 2WTR-B. The module uses a form C zone relay to initiate “out of sen-
sitivity” and “freeze trouble”, a form A zone alarm relay and a second form
A zone relay to indicate loop fault. An EZ Walk Test puts all detectors on the
loop into a Walk Test mode for easy verification of detector loop wiring. The
module allows 2-wire smoke detectors to be used on any compatible 4-wire
control panel and provides Style D wiring on the detector loop.
VISIBLE ANNUNCIATON
The MOD2W has three visible LED’s: The green LED is a supervisory LED; it
blinks during power on, reset, and during normal operation. The yellow LED
is used to indicate a loop wiring fault and will blink when it is in EZ Walk test
mode. The red LED signals smoke events; it blinks during smoke maintenance
events and lights constantly during smoke alarm events.
