Description

2 wire conventional smoke detector en54-7 smoke alarm sensor

General Description

The device is photoelectronic 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 control
panel.
Two LEDs on each detector provide local 360° visible alarm indication. They flash every 3~5 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 detector can be reset only by a momentary power interruption  

Features and Benefits
Compatible with all the conventional fire alarm control panel Unpolarized wire input. Wide range of operating voltages. Unique optical sensing chamber. Built in microprocessor intelligent software. Two LEDs blink standby, provide 360° visibility. Insect-resistant screening. Twist-on mounting base with tamper lock. Drift compensation and smoothing algorithms. Remote Indicator LED can be connected.
