Wired INTERCONNECTED Smoke Detector for 12v Normally Opened (NO) Alarm Systems OR without Alarm System - 12 Volt

Detector Overview
This wired 12-volt interlink smoke detector will sound ALL smoke detectors in every room using a common interlink/alarm wire.  It runs on 12v and uses a normally open alarm circuit.  Only 3-wires are required.

It uses both ionization and photoelectric smoke sensors for higher performance. The photoelectric sensors are set to industry standards to help prevent false alarms like through cooking or using candles. They also respond faster to fires give you and your family more time to leave the house safely.

Interconnect System
When smoke is detected, ALL smoke detectors will sound an alarm. In addition, the smoke detector that detected smoke will display a solid red LED light.
Use With or Without an Alarm System
These interlinked smoke detectors can be used by themselves or they can be connected to any normally open (N/O) zone on an alarm alarm system. 12-Volt power supply is not included.

Wired Connections
This wired smoke detector uses 3 wired connections in total. 
Two connections are for power (+) and (-). 
One connection is used for the Normally Opened (N/O) circuit for the INTERLINK feature.  It is also a shared wire to connect them to an alarm system.

Features
Test button on smoke detector for easy testing.
Photoelectric detection to reduce false alarms (i.e. cooking in the kitchen)
Sensitivity control inside detector.
Automatic reset when smoke dissipates.
