2 Wire smoke alarm DC9-25V smoke detectors work with Conventional panel

1. GENERAL DESCRIPTION

TPRODUCT INTRODUCTION

This product named Photoelectric smoke detector(hereinafter called detector) detects the smoke by a couple of infrared diodes. The principle of detecting is granule in the smoke can reflect infrared light. Infrared diodes are placed in the special chamber. The chamber can shield external light, but doesn’t affect the smoke into it. While there is no smoke, the diode can receive very weak infrared light. When the smoke entering the chamber,diode can receive more and more light,and the detector can give out alarm signal when the smoke attains the certain density. In order to reduce the interference and lower power consumption, the emitting circuit adopts the pulse signal.

Dear Friends, Please kindly Note:

1. Please understand the relationships between the value of Invoice declaration(for custom clearance) and the risk in your country, such as Brazil. Much lower value declaration may cause problem/risk during custom clearance. 2. Please leave a tax number under your order for delivery requirement. 3. All international expresses delivery are not allowed to send battery, so Batteries are not included in the independent smoke, the encoder and panel shipments. 4. For the free shipping products , we will choose one express which is convenient for both of us .If you don’t like any specific international express, please feel free to tell us, we will change to another.

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 .
