1. Overview of JTY-GD-G3T point-type photoinductor fire detector:
JTY-GD-G3T point-type photoinductor fire detector (hereinafter referred to as the detector) is a point-type photoinductor fire detector developed using the principle of infrared scattering.The JTY-GD-G3 detector has a novel structure, beautiful appearance, stable and reliable performance, and strong moisture resistance. It is suitable for hotels, hotels, office buildings, teaching buildings, banks, warehouses, libraries, computer rooms and distribution rooms.
2. Features of JTY-GD-G3T point-type photoinductor fire detector:
1. The address encoding can be written in advance by the electronic encoder or directly changed by the controller, making engineering debugging simple and reliable.
2. The microcontroller can sample and process data in real time, and can save 14 historical data, and the curve display tracks the on-site situation.
3. It has temperature and humidity drift compensation, dust accumulation degree and fault detection functions.
4. Polarity-free two-bus signal.
3. Technical characteristics of JTY-GD-G3T point-type photoinductor fire detector:
1.JTY-GD-G3T smoke sensor probe working voltage: signal bus voltage: bus 24V A allowable range: 16V ～ 28V
2.JTY-GD-G3T working current: monitoring current≤0.8mA Alarm current≤1.8mA
3. Indicator light: alarm confirmation light, red, flashes during patrol, always on when alarm is called
