JTY-GD-DG311联网型光电烟温复合火灾探测器(以下简称探测器)适用于商场、宾馆、商店 、仓库、电机房等民用及工业场所的火灾预报警。探测器具有灵敏度高、稳定可靠、耗电小、美观耐用、使用方便等特点,可与安防系统配套使用

一. 性能:

报警声音: ≥80dB

供电电源: DC9V~DC28V

电    流:  静态电流 ≤200uA

 报警电流 ≤45mA

工作温度: -10℃~+50℃

相对湿度: ≤95%RH(40℃±2℃)

输出形式: 声光报警/继电器无源触点(NO/NC可设置)输出

烟雾灵敏度:1.06±.26%FT.

温度报警级别:A1R

符合标准:GB4715-2005,GB4716-2005

二. 功能:

 自检:按下检测按钮,探测器LED常亮,同时发出报警音响(注:自检仅对于探测器本身内部功能进行检测,自检时无继电器信号输出)。

工作:正常情况下,探测器大约每隔6秒指示灯会闪亮一下。探测器自动检测周围环境中的烟雾浓度和温度变化,并根据使用环境状况进行灵敏度自动补偿。当烟雾浓度或温度接近报警值,探测器加快对烟雾浓度或温度趋势进行智能运算,同时报警指示灯开始闪亮。若运算结果达到或超过报警值,探测器开始声光报警,并启动继电器输出。当周围环境的烟雾浓度和温度降低到报警值以下时,探测器自动恢复正常工作状态。

输出:无源触点输出;触点容量24V/1A,可通过探测器内部的跳线,设置为常开或常闭触点输出。出厂时跳线默认设置触点为常闭。

General

YT142 Smoke Detector with sound and relay output, Operates by Advanced MCU Expert Algorithm Software.

Key Specifications/Special Features

  • They work perfectly with all conventional intelligent fire control panels
  • Advanced MCU Expert Algorithm Software.
  • Easy installation and maintenance
  • Durable sensor head, no need for replacement
  • SMD circuit board design-satisfactory quality and reliability guaranteed

The detectors are photo-electronic detector uses a state of-the-art
optical sensing chamber. This detector is designed to provide open
area protection and to be used with most security alarm control
panel.
Two LEDs on each detector provide local 360° visible alarm
indication. They flash every six seconds indicating that power is
applied and the detector is working properly. The LEDs latch on in
alarm. LEDs will be off when a trouble condition exists indicating
that the detector sensitivity is outside the listed limit. The alarm can
be reset only by a momentary power interruption.
The detector that initiated the alarm condition will have its red LED
and relays latched until reset by panel.
Heat detector and smoke & heat detector combine a photo
electronic sensing chamber and a temperature heat detector.
