Model JTY-GD-2151EIS is a conventionalintrinsically safe photoelectric smoke detector usesstate-of-the-art sensing chamber. The detector isdesigned to provide open area protection and is foruse with 2-wire control panels via interface module.Each detector is equipped with two LEDs thatprovide a local, visual indication of detector status.Once the detector senses a fire, it latches on inalarm and remains the state until it is reset by amomentary power interruption. The detector can betested by activating an internal reed switch with atest magnet.Model JTWB-BCD-5151EIS is a conventional 2-wire intrinsically safe thermal detector. Thisdetector is designed to provide open areaprotection and is for use with 2-wire control panelsvia interface module. The detector utilizes a stateof-the-art thermistor sensing circuit for fast andaccurate response. It can be used in variousenvironmental conditions and also has the simplemaintenance and lower fault rate advantages. Twored LEDs blink in standby status each 5S and latchon in alarm, and stop blinking in fault. A built-in testswitch is designed for product testing.§ Exia II CT6(JTY-GD-2151EIS, JTWB-BCD-5151EIS)§ 360° visible LED indicator§ Tamper-resistant design§ SEMS screws for easy wiring (B401)§ Low operating current§ 3-year warrantyFeatures
