2 wire Conventional Heat Detector WT105C work with DC9-28V

1. GENERAL DESCRIPTION
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 conventional fire alarm 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.

3. INSTALLATION
NOTE: All wiring must conform to applicable local codes,
ordinances, and regulations.
INSTALL THE DETECTOR BASE
1. Open area smoke or heat detectors are intended for mounting on a ceiling or a wall in accordance with the fire
standard in your country.
2. Attach mounting base to ceiling or wall. The base of the detector can be mounted directly onto an electrical
junction box such as an octagonal (75mm, 90mm or 100mm), a round (75mm), or a square (100mm) box
without using any type of mechanical adapter.
3. Position all wires flat against terminals, and fasten the wires on the terminals,

4. Terminals functions description:
Terminal 2: IN+( Zone Input+)
Terminal 5: IN- (Zone Input- )
Terminal 6: IN+( Zone Output+)
Terminal 5: IN- (Zone Output- )
Terminal 6: Remote Indicator+
Terminal 3: Remote Indicator

多线型感温火灾探测器(以下简称探测器) )采用2线制工作模式，配合多线制火灾报警控制器使用，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。注：探测器报警时将其两端的电压钳位在5V～11V之间。至于电流的大小则取决于控制器的限流情况，不允许直接用24VDC供电，否则探测器会因无限流电阻而烧坏。正常使用时与多线报警主机或卷帘门控制箱等设备配套使用。探测器报警后，需要通过断电的方式复位。
