Product overview
1.1
JTW-ZD-A20KE point-type heat fire detector (detector hereunder) is a two-wire switch-type
temperature detector. The detector adopts a non-polarity two-wire connection, which can
be applied in the compatible conventional switch quantity alarm control system and
monitoring alarm system, and it can also be connected to the intelligent fire alarm control
system through the input module. The detector monitors the temperature of the working
site in real-time. When the detector is in the monitoring status, the red indicator light
flashes and the working current is small. When the field temperature exceeds the set alarm
threshold, the detector enters the alarm status, the red light is steady, and the loop current
increases rapidly. The alarm signal of the detector is transmitted in the form of a loop
current change and has the alarm locking function, and the reset of the alarm can only be
realized by a short power failure.
1.2
The detector is suitable for places where a lot of heat is generated when a fire occurs, such as kitchens, boiler rooms,
generator rooms, drying workshops, smoking rooms and other industrial and civil buildings. It is not suitable for places
where a large amount of smoke and a small amount of heat are generated when a fire occurs.
