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 i
4
series module is designed to interface between compatible i
4
series
combination CO/smoke detectors (Model COSMO-2W and COSMO-4W) and
compatible security/fire panels. It can also be used to retrofit compatible i
4
series detectors into an existing loop of i
3
smoke detector models 2WTA-B or
4WTA-B, without adding wires. The module interprets signals and translates
them into a separate smoke zone and a separate CO zone, each with alarm
and trouble signals. When signaled by the panel, a module will synchronize
connected detector sounders in either Temporal 3 or Temporal 4 pattern. Local
status indication is provided by 4 LED’s and a 3 position DIP switch enables
user configuration.
The i
4
COSMOD2W, 2-wire interface module, offers additional functionality
including:
• Ability to query for a “need for maintenance” condition from 2-wire i
4
series model COSMO-2W and i
3
series model 2WTA-B smoke detectors
• One relay is available to indicate a multitude of maintenance conditions
at the control panel
• All conditions are displayed at the module and at the detector
• EZ Walk test mode allows the installer to easily verify that all detectors
on a loop are operational
• Allows 2-wire smoke detectors to be used on any compatible 4-wire
control panel and provides Style D wiring on the detector loop
fEATURES
• Compatible with System Sensor i
4
series combination CO/smoke detectors
and System Sensor i
3
Series smoke detectors models 2WTA-B or 4WTA-B.
• Allows up to 12 compatible devices including the i
4
series combination
CO/smoke detector to be integrated with a panel
