MCT-442
Supervised Indoor Wireless CO Gas Detector
1. INTRODUCTION
The carbon monoxide (CO) detector is designed to monitor the
CO gas level in residential dwellings and give early warning
before potentially dangerous levels exist. The CO alarm is
transmitted to the PowerMax+ (version F and up) or PowerMax
Pro and presented on its display.
The CO gas is considered to be a highly dangerous poisonous
gas because it is colorless, odorless, tasteless and very toxic.
Presence of CO gas inhibits the blood's capacity to transport
oxygen throughout the body, which can eventually lead to brain
damage. CO gas is produced by incomplete combustion of fuels
(such as natural gas, propane, heating oil, kerosene, coal,
charcoal, gasoline or wood) that can occur in any device that
depends on burning for energy and heat (such as furnaces,
boilers, room heaters, hot water heaters, stoves, grills and in any
gasoline powered vehicle or engine).
Before CO harmful level is reached, the detector's internal buzzer
beeps sound periodically and the detector's red LED flashes. In
this condition, the buzzer sound can be stopped for 6 minutes by
pressing the TEST/MUTE switch. It will not correct the CO gas
problem, but will temporarily silence the buzzer while you correct
the problem. After 6 minutes, the detector restarts alarm if the CO
level remains high.

Installation Instructions

The detector provides
low battery and detector
end-of-life indications.
Caution: The detector
expiry date is stamped
on the detector. After
the expiry date, the
detector should not be
used - do not wait for
end-of-life indication!!
The detector is continuously self-tested and has a TEST button
that enables the user to test the detector anytime.
Note: The TEST/MUTE switch functions as TEST switch (in
normal operation) or as MUTE switch (in alarm condition).
The tamper switch actuator (fig. 3), is pressed against the bracket
when the unit is attached to the bracket. Removal of the unit from
the bracket causes the switch contacts to open, creating a tamper
event, which is reported by the transmitter to the alarm system
control panel.

the first 4 minutes.
** After 6 minutes, the detector restarts alarm if the CO level
remains high.
Note: Long period of low battery condition may cause improper
function. In case of End-of-Life/Fault indication, replace the
battery and check if the End-of-Life/Fault indication still exists. If it
still exists, stop using the detector.
