Dual Sensor smoke Alarms : 20 results priced between £5.00 and £50.00

This Kidde smoke alarm units benefits from using both ionisation and optical technologies. Ionisation responds quickly to fast flaming fires whilst Photo Electric responds quickly to slow smouldering fires. Battery operated smoke alarm (alkaline battery included) 5 year warranty on alarm CE Marked UL approved Test / Hush button Low battery LED indicator and alert

Budget Kidde Smoke Alarm Dual sensor Ion/Photo cw hush Dual Sensor Smoke Alarm What is the best type of smoke alarm. Let’s start with the answer: Within the fire protection and prevention industry, it is recognized that neither sensor type, photoelectric nor ionization, is universally better at detecting all types of fires. Why? Each sensor operates on a different principle and therefore may respond differently to various conditions. Ionization sensors may respond slightly faster to flaming fires...

Dual-sensor smoke alarm features photoelectric and ionization sensors for the best overall protection. Ionization Sensor may detect invisible fire particles (associated with flaming fires) sooner than photoelectric alarms. Photoelectric Sensor may detect visible particles (associated with smoldering fires) sooner than ionization alarms. Hush feature temporarily silences nuisance alarms. Battery-operated smoke alarm provides continuous protection even during power outages. Easy-to-install smoke alarm...

The EV-DP dual wavelength photoelectric smoke sensor has two terminals for connection onto the two wire loop. The remaining terminals provide a switched current sink function which operates when the detector goes into alarm condition, suitable for the operation of an auxiliary function such as a remote indicator. Terminal 3 (RIL) is limited to 3mA. Terminal 2 (Base Control) is not current limited.

The Ei 2110 is a multi-sensor fire alarm that contains two separate sensing elements – optical and heat. As the unit monitors two different by-products of fires (smoke and temperature), its response to all fire types is vastly improved over traditional single sensor alarms. 230V hard-wired smoke and heat alarm Multiple sensor elements - optical and heat Unique dust compensation feature (the alarm automatically adjusts for any contamination within the optical sensor chamber) Kitemarked to BS EN 1...

The Ei428 RadioLINK Relay Module is powered by the 230VAC mains and has rechargeable back-up cells. As supplied the relay operates continuously (i.e. it switches when one of the smoke/heat alarms detects fire and switches back when the smoke clears). When the slide switch is removed to the pulse "P" position the relay will switch when fire is detected but will automatically switch back after 5 seconds. This is commonly used with warden call systems where only momentary short circuit signalling is...

It is designed for use with the EasiFit range of Mains Powered Smoke/Heat Alarms. The RadioLINK Base itself, is also mains powered and has rechargeable Lithium cells for back-up in the event of mains failure. The RadioLINK Base will normally be wired to the nearest mains circuit in the ceiling (usually the lighting circuit). The Smoke/Heat Alarm is then slid on to the RadioLINK Base rather than to its normal mounting plate. As many as 12 units can be interconnected in this way.
