NOTICE: This manual should be left with the owner/user of this equipment.

IMPORTANT: The detector must be tested and maintained regularly following the proper authorities? requirements. The detector should be cleaned at least once a year.


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.

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 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-


1.Allof international expresses delivery is not allowed to send batteries, so the independent smoke, the encoder and panel are not included in the batteries. 2.For the free shipping products , I will choose one express I like and you donot hate.If you don’t like one of the international expresses, please tell us, we will choose another international express.

We produce a variety of independent sales distribution smoke detectors , combustible gas detectors, fire alarm systems, security alarm systems products among consumers enjoy a higher status . With many retailers and agents to establish a long-term stable cooperative relations .
