Visonic MCT-425 Installation Instructions Manual

MCT-425 MCT MCT MCT -425 -425 -425
Supervised Wireless PowerCode Smoke Detector
1. DESCRIPTION AND APPLICATIONS
The MCT-425 is photoelectric smoke detector designed to sense
smoke, but not gas, heat or flame and fitted with a Power-
Code-type UHF transmitter. It provides early warning of developing
fire by sounding an alarm with its built-in alarm horn, and by
transmitting a coded alarm signal to a PowerCode receiver or to a
compatible wireless alarm control panel.
It must be borne in mind, though, that effective pre-warning of fire
accidents is only possible if the detector is located, installed and
maintained properly as described in this manual.
WARNING: This smoke detector is designed for use in a single
residential unit only, which means that it should be used inside a
single family home or apartment. It is not meant to be used in
lobbies, hallways, basements or another apartment in multi-family
buildings, unless there are already working detectors in each
family unit. Smoke detectors, placed in common areas outside
the individual living unit, such as on porches or in hallways, may
not provide early warning to residents. In multi-family buildings,
each family living unit should obtain its own detector.

WARNING: This detector is not meant
to be used in non-residential buildings.
Warehouses, industrial or commercial
buildings and special purpose non-
residential buildings require special fire
detection and alarm systems. This
detector alone is not a suitable
substitute for complete fire detection
systems for places where many
people live or work, such as hotels or
motels. The
dormitories, hospitals, nursing homes
or group homes of any kind, even if
they were
once single family homes. Please refer to NFPA 101, the Life
Safety Code, NFPA71, 72A, 72B, 72C, 72D and 72E for smoke
detector requirements for fire protection in buildings not defined as
"households".
WARNING: This detector, if used as a stand-alone unit, will not
alert people who are hard of hearing.

2.3 Definitions of LED Light and Buzzer
The red and yellow LED light and buzzer turn on and/or off to
indicate various situations. There are several LED light and
buzzer operations.
A. When the red LED flashes every 30 seconds, this means
power on, i.e., the detector is energized.
B. When the red LED flashes and the buzzer beeps intermittently,
this means alarm for potential smoke hazard.
C. When the red LED flashes together with buzzer beeps for every
Default
30 seconds with temporal tone 0.5 second on and 0.5 second
ON
off intermittently, this means battery power is low.
D. The yellow LED turns on every time an RF signal is transmitted
ON
to the control panel.
