2 Wire - 4 Wire Smoke Detector

Smoke alarms sound their alarm horn when they detect smoke.Everything preventing the smoke from reaching the alarm obstructs an early alarm.
A single smoke detector provides only limited security.Fire in another room will only be detected after smoke reaches the alarm.It is therefore recommended to install a smoke alarm on every level of the home if not in every room.Inform yourself about fire safety rules and proper behaviour in case of a fire at your fire brigade!

Product characteristics
Photoelectric effect
This recently developed photoelectric sensor-camber is insensitive to interfering influences.Every device is separately calibrated in order to avoid false alarms due to,e.g.cigarette smoke.The power supply is electronically regulated,thereby maintaining a constant sensitivity of the alarm.
Battery operation
The functioning of the detector is maintained even in case of a power failure.On an average the battery's(standard 9V battery)service life is 1year.
Signal lamp(LED)
A flashing small light(every 43s)signalises a failure-free operation
