Visonic MCT-425 - User Manual

D-301296 1
MCT-425, MCT-425C
Supervised Wireless PowerCode Smoke Detector
Installation Instructions
1. DESCRIPTION AND APPLICATIONS
The MCT-425 and MCT-425C are smoke-automatic fire detectors
with integral audible signal for open area protection, designed to
sense smoke (not gas, heat or flame) and fitted with a PowerCode
type UHF transmitter. MCT-425C is for CANADA only.
The smoke detector 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. For UL approved installation use only
PowerMax+ control panel.
It must be borne in mind, though that effective prewarning of fire
accidents is only possible if the detector is located, installed and
maintained as described here.

SMOKE DETECTOR
Alarm Sound Level: 85 dB at 3 m (10 feet)
TRANSMITTER AND CODING
Operating Frequency (MHz): 315, 433.92, 868.95, 869.2625 or
other frequency according to local requirements.
Transmitter's ID Code: 24-bit digital word, over 16 million
combinations, pulse width modulation.
Overall Message Length: 36 bits
Supervision: Automatic signaling at 60-minute intervals (315
MHz version), 15-minute interval (433.92, 868.95, 869.2625 MHz
versions) or according to the local standards.
Tamper Alerts: Tamper event (removal of the unit from its bracket)
is reported once. Tamper restore is reported when the tamper
switch is restored.
Transmission Indicator: Yellow LED lights upon transmission
(visible only when Switch SW-1 is ON).
ALARM REPORT:
Every 20 sec. for the first 3 minutes.
Every 3 min. for the next 27 minutes.
Alarm stops reporting after 30 min., or if the detector goes into
"alarm restore".
ELECTRICAL DATA
Power Source: 9 Volt alkaline or lithium.
Operation Voltage: From 7.2 V to 9 V.
Current Drain: 28 µA standby, 20 mA in operation
Smoke Density:
Europe: 0.15 – 0.2 dB/m
USA & CANADA: 0.61%/ft to 1.27%/ft
Cover Range: 50 cubic meters (1765.5 cubic ft.)
Battery Life Expectancy:

Lithium: at least 1 year (for typical use) for battery type
Ultralife # U9VL-V.
Battery Supervision: Automatic transmission of battery status
data as part of any transmitted message.
Audible and Visual Low Battery Warning: Built-in horn beeps
every 30 seconds simultaneously with red LED flashing (for up to
30 days when the battery voltage drops).
Audible and Visual Degraded Chamber Sensitivity Warning:
Built-in horn beeps every 30 seconds in the middle of red LED
flashing intervals – indicate that the sensor should be cleaned.
Clean Warning Transmission: A clean (maintenance) signal is
transmitted when the detector's chamber sensitivity becomes
degraded.
Note: This transmission applies to the PowerMax+ control panel only

3.2 Setting the Function Switch
The MCT-425 and MCT-425C have a 4-position DIP switch
function selector (see Figure 3). The switch levers are numbered 1
to 4, and each switch allows you to select one of two options.
Set the function switches as desired. The ON position is indicated
on the switch body.
