Conventional

JTW-ZD-920KE point-type fixed temperature heat detector (Detector hereunder) is a two-wire switch-type temperature-sensing detector. As a non-polar two-wire connection is adopted in the detector,it is compatible in conventional switch-type alarm control systems and monitoring alarm systems. The detector can also be connected with intelligent bus fire alarm control systems via a interface module. The detector monitors temperature in the workplace in real time. While monitoring, the red indicator blinks and the working current is low. When the work site temperature has exceeded the preset alarm threshold, the alarm detectors and the red indicator remain on, while the loop current is increased. The detector’s alarm signal can be locked and is displayed by changes in the loop current. The alarm can only be reset by the instant power disconnection.

The detector is applicable in places where fire might generate volume heat, i.e. in industrial and civil buildings such as in the kitchen, boiler room, generator room, drying plant, and smoking room. However,it is not suitable for places where volume smoke and low heat is generated during a fire, or a place where a smoldering fire might occur.
