Wiring Instructions for the CMD-4M(R)
Follow all applicable codes and regulations for wiring. Use at least 18 AWG, UL
Listed, stranded wire that can be found at your local hardware store for all
connections. Connect the red wire to a 12V source (battery preferred) and the
black wire to Ground.

CONTINUOUS OPERATION IS PREFERRED.
If your power is unlimited, it is
recommended that the CO Sentinel be operated continuously day and night. The CO
Sentinel was designed to minimize current draw in order to allow for direct wiring to a
battery. This is the “healthiest” condition for solid state devices. In addition, it provides
advance warning when entering an area where a hazard may exist.
NOTE: For installations differing from those outlined above, please contact the
engineering department of FIREBOY-XINTEX for application and suitability information.
Wiring for CMD-4M(R)-RLY (Relay/Interconnect Version)
Interconnect wiring
To interconnect multiple units the yellow and brown wires (4-wire harness) need to be
tied in parallel (see below). In this mode of operation only the unit detecting CO will go
into a true alarm and actuate its relay opening the contacts. Interconnected units will
produce an audible and visual alarm but will not open their relay contacts.
Relay wiring
This unit is designed with a relay for generator shutdown. The relay contacts are closed
when the unit is powered and in normal operation and open during alarm or when the
test/silence button is pressed. Because the only unit that opens the relay contacts is the
unit that detects the CO it is necessary to wire all relay contacts in series so that any unit
detecting CO has the ability to shutdown the generator.
