Product Description

WT105 Conventional Heat Detector

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,
