DESCRIPTION
MCT-425 is photoelectric smoke detector fitted with a PowerCode™ fully supervised UHF transmitter. It is designed to sense smoke, but not gas, heat or flame. The detector provides early warning of developing fires by sounding an alarm with its built-in alarm horn, and by transmitting a coded alarm signal to a wireless alarm control panel. The fire alarm initiated by the MCT-425 allows people present within the protected area to escape before the fire spreads or to put out the fire.



SPECIFICATIONS

SMOKE DETECTOR
Detection Sensitivity: 2.3 ±1.2 %/ft 
Alarm Sound Level: 85 dB at 3 m (10 ft)
Audible and Visual Degraded Chamber Sensitivity Warning: Built in horn beeps every 30 seconds in the middle of the red LED flashing intervals. This indicates that the sensor should be cleaned
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)

TRANSMITTER AND CODING
Operating Frequency (MHz): 315, 404, 418, 433.92 or other frequencies according to local requirements
Transmitter ID Code: 24-bit digital word, over 16 million combinations, pulse width modulation
Overall Message Length: 36 bits
Alarm Reporting: Every 20 sec. for the first 3 minutes, then every 3 min. for the next 27 minutes. Alarms stop reporting after 30 min., or if the detector goes into "alarm restore".
Supervision: Automatic signaling at 60-minute intervals
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 with SW-1 set to ON)
