MCT-442
Supervised Indoor Wireless CO Gas Detector
for UL Installation
Installation Instructions
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
P (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.
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!!

- General View
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.
