Product features

•Battery-operated stand-alone Home Smoke Detector working on photoelectric principle.

•Automatic self-test for smoke-sensing electronics, therefore extremely reliable and immune to

interference.

•Option of operating as a wireless network with radio transmitter modules and a wireless alarm unit

(available as extras).

•

Loud pulsating warning tone if sm

oke detected, approx. 85 dB (A).

•Battery low-power monitor (LED and short beeps at intervals) warns that battery voltage is

growing weaker, for up to about 30 days.

•Contamination/fault warning function with LED and short beep.

•Option of operating as a wired network with relay modules (available as extras). Up to 40 smoke

detectors can be linked together. If one smoke detector identifies a fire, the alarm is relayed all the

other smoke detectors in the network.

•

Integrated test button: if the smoke detector

emits its warning tone when the test button is

pressed, it is in good working order.

•Simple mechanical safeguard prevents smoke detector clicking into place in its base if no battery

is fitted.

•

Damage to the detector is not possible if the

battery is installed with the wrong polarity.

Operating principle

The smoke detector is an early warning device for smouldering fires as well as flaming fires that

develop smoke. It operates on the proven light scatter principle. lnside the sensing chamber a light

source and a light sensor are arranged so that light normally does not fall on the sensor. It is only

when airborne particles enter the chamber that light is scattered onto the sensor (Tyndall effect) to

produce an electrical signal. This design means that no radioactive source is required. Smouldering

fires in particular are quickly identified by the smoke detector and the alarm given.

If smoke enters the sensing chamber, the built-in sounder is triggered. A logic circuit to eliminate false

alarms delays the alarm signal and resetting by up to 30 seconds.

This product has been approved by the Schadenverhütung GmbH in Cologne (VdS). Only security

products meeting the high quality demands of the prEN 12239 receive this approval.

Important test criteria are:

•reliable smoke detection characteristics

•good smoke entry

•immunity to electrostatically discharge

•functional check and battery presence control

• Test button
