Model JTY-GD-2151EIS is a conventional intrinsically safe photoelectric smoke detector uses state-of-the-art sensing chamber. The detector is designed to provide open area protection and is for use with 2-wire control panels via interface module.Each detector is equipped with two LEDs that provide a local, visual indication of detector status.
Once the detector senses a fire, it latches on in alarm and remains the state until it is reset by a momentary power interruption. The detector can be tested by activating an internal reed switch with a test magnet.
Model JTWB-BCD-5151EIS is a conventional 2- wire intrinsically safe thermal detector. This detector is designed to provide open area protection and is for use with 2-wire control panel via interface module. The detector utilizes a state-of-the-art thermistor sensing circuit for fast and accurate response. It can be used in various
environmental conditions and also has the simple maintenance and lower fault rate advantages. Two red LEDs blink in standby status each 5S and latch on in alarm, and stop blinking in fault. A built-in test switch is designed for product testing.
