Photo-electric Optical Smoke Alarm Wired with 9V Battery

This Photo-electric Optical Smoke Alarm uses the light scatter principle (which detects smoke particles entering the optical chamber of the alarm) to respond rapidly to a domestic fire. It has an Easi-Fit base that enables a quick installation and easy maintenance. The alam is wired with a replaceable 9V alkaline battery which may last for up to 4 years in standby mode or 2 years if unpowered from the mains. It has a high performance optical chamber with integral fixed insect screen to avoid false alarms. It also has a prominent Test/Hush button. This unit can connect with up to twelve alarms, where if any alarm is triggered, all alarms shall be activated. This product has a 5 year (limited) warranty. Sensor: Optical, uses light scatter from smoke particles. (Note: Sensing chamber meets the 25mm stand-off installation requirements of AS1670.1 and AS1670.6) Ambient Light: Chamber housing and compensation overcomes possible problems due to stray light Sensitivity: Complies with AS 3786 (Nominal 10%Obs/m) Source: Contains NO radioactive material Airspeed: Essentially immune to the effect of airspeed Test Facility: Simulates the effect of smoke and checks electronics and horn Automatic Self-Test: Smoke chamber is tested every 40 seconds and unit beeps (without LED flash) if the sensor is de-graded Insect Screen: 1mm diameter stainless steel mesh mitigates insect and debris entry into the smoke chamber Hush Facility: In “Hush” mode the alarm enters a ten minute period of reduced sensitivity to overcome false alarm conditions, and will then automatically reset itself Primary Supply: 230 Volts AC Power-On Indicator: Continuous Green LED Secondary Supply: 9 Volt Alkaline Battery Low Battery Warning: Beeps every 40 second when the stand-by battery reaches it depletion threshold Alarm Sounder: Integral electronic piezo horn Alarm Sounder Connection: Piezo contacts are soldered to prevent failure due to contact corrosion over time Alarm Sounder Output: 85dB (minimum) at 3m Alarm Status Indicator: Red LED flashes every second on device sensing fire. Temperature Range: 0 to 40°C Humidity Range: 15% to 95% Relative Humidity Interconnection: Up to 12 140 series smoke or heat alarms, along with one EIB128 relay base, may be interconnected. (but NOT to other manufacturer’s devices) Fixing: Easi-Fit mounting base Enclosure Material: UL94VO flame retardant Dimensions: 152mm diameter x 50mm depth Weight: 345 grams Warranty: 5 year (limited) warranty Approvals: Certified to AS3786 ActivFire afp 1578
