Smoke Detector EN54 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 alarm 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. SPECIFICATIONS Operating Voltage Range: 9 to 28VDC Volts Non-polarized Standby Current: ≤*DC Maximum Alarm Current (LED on: ) ≤*DC Operating Humidity Range: 10% to 93% Relative Humidity, Non-condensing Operating Temperature Range: 14°F to 122°F (-10°C to50°C) Adjustable Sensitivity: 0.15～0.3dB/m Height: 2.2˝ (55 mm) installed in Base Diameter: 4.0˝ (103 mm) Weight: 5.5 oz. (155 g)
