JTW-ZD-620 wireless point-type heat sensing fire detector (hereinafter referred to as the detector) is a built-in wireless communication module for heat sensing fire detection. It can collect real-time field temperature information, detect the ambient temperature in case of fire, and report fire alarm signal to the controller through wireless communication. The detector is powered by two DC1.5V AA lithium iron batteries in series, with low power consumption and battery voltage detection circuit. In case of battery undervoltage, the detector can report to the controller. The detector is suitable for places where a lot of heat is generated when fire occurs, but not for places where a lot of smoke and a little heat are generated when fire occurs.
