DC Powered 4-Wire Smoke / Smoke Detector with Relay Output
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 5-6 seconds indicating that power is applied and the detector is working properly. The LEDs latch on in alarm, will be off when a trouble condition exists indicating that the detector sensitivity is outside the listed limit. The detector can be restored to normal status automatically when the ambient smoke or temperature below the alarm value.
Heat detector and smoke & heat detector combine a photo electronic sensing chamber and a temperature heat detector.

NOTE: All wiring must conform to applicable local codes, ordinances, and regulations.
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, See Figure 1.
4. Terminals function description:
Terminal 1: Relay Output -COM
Terminal 2: Relay Output NO/NC (default NO)
Terminal 3: DC Power
Terminal 4: DC Power +
