Can monitor air and detect smoke with optical principles. When it reaches the maximum amount that the chamber can bear, it will alert.LED light flash indicator.Low battery indication.With a test button: can take analog alarm tests of the smoke alarm.
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,there by 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 1 year
Signal Lamp(LED):
A flashing small light( every 43s) signalises a failure-free operation.
Fully automatic test function;
Andvance electronics ensure the best possible operation readiness by means of an automatic self-test function.
Battery warning function:
By means of a warning sound repeated every 43 seconds( for up to one month),the smoke detector signalises that the power supply of the battery is insufficient and it needs to be replaced.
Control button:
Temporarily increases the detector\'s sensitivity to test the alarm function.
>>>Function:
Smoke caused by fire is very dangerous. especially because of today\'s widespread use of synthetic materials in modern homes that might generate poisonous vapours when burning .
The smoke alarm detects smoke caused by smouldering at an early stage and warns by means of a loud. vibrant sound.thereby waking inhabitants up at a point of time when a safe escape is still possible.
The smoke alarm operates according to the scattered light principle .A light source and a photocell are arranged so as to ensure that normally no light striked the photocell. The light source is activated in short intervals.
if the concentration of smoke particles in the enclosure reaches a certain level,the light is reflected and reaches the photocell this will set off a loud fire alarm.
