wireless interlinkable smoke detector with lithium battery operated

Specifications 1.wireless interconnected smoke detector/sensors/alarm

2.Photoelectric sensor

3.Easy installation and maintenance

wireless interlinkable smoke detector  DP-05I      This detector has been design with both transmitter and receiver in the electronics.  Detectors could be wireless interlinkable with each other. Once one unit alarms, it will send alarm signal to trigger the other alarms.  It has a DIP switch for setting the detectors ID to avoid receiving other similar alarm signals.   Only detectors with the same ID can make up an interconnection group. Features:      * Infrared photoelectric sensor   * MCU processing * Auto-reset after smoke clears * Sound & flash alarm * LED indicator * Test & Hush button * Low battery indication * Dustproof, mothproof and anti-white light design     Techinical Parameters:
