Frequently asked Questions Mains Powered Smoke, Heat and RF Alarms
DESCRIPTION OF MAJOR FEATURES 1. What types of Smoke Alarms are available? Smoke alarms incorporating either an Ionisation or an Optical sensor are available in mains only, mains with Alkaline battery back-up, or mains with rechargeable Lithium back-up formats. Heat Alarms are also available in these ranges, but these only sense heat, not smoke. A comprehensive Fire Alarm system will contain all 3 elements of detection. 2.
cause of ignition of furniture or bedding is by a cigarette. Ionisation types are considered to be more suited for use in rooms where a fast flaming fire may present a greater danger, dining rooms and bedrooms being possibilities. The standard now recommends that in new build properties heat alarms should be installed in kitchens and the 'Principal habitable room' eg the living room; in addition to any smoke alarms used in the escape routes.
10. Will they always work? The only restrictions to the correct operation of a Smoke Alarm system in a fire situation are: that there are a sufficient number of alarms in the system, sufficient smoke reaches the alarms, they are correctly installed and sited, and that they are regularly maintained and tested for correct operation. If all of these factors are right, there is a very high probability that sufficient warning will be given in life-threatening situations caused by a fire. FITTING 11.
16. Can I use a relay to signal other devices? There are a number of options available for using a relay with Ei Smoke and Heat Alarms. All the relays have volt-free output contacts rated at up to 240V and have both Normally Open and Normally Closed connections. There are relay options available for use with mains operated devices such as bells, sounders and door closers.
21. How long will the battery last? This will depend on a number of factors that will differ slightly according to the type of alarm in use. The 140 series alarms are supplied with an Alkaline battery which, dependent on conditions, can provide up to 4 years standby supply, up to 2 years without mains power. The 150 series and the 160 series alarms are fitted with rechargeable Lithium power cells which are continuously charged by the alarm circuitry.
25. What is the radiation risk from Ionisation Smoke Alarms? The National Radiological Protection Board (NRPB), UK have carried out extensive tests on Ei professional Ionisation Smoke Alarms and have concluded that they are radiologically safe. They estimate that we recieve 10,000 times as much radiation from our surroundings as we would from an ionisation alarm in normal use. 26.
RADIOLINK - FREQUENTLY ASKED QUESTIONS 1. What is RadioLINK? It is a totally new concept enabling smoke alarm systems to be interconnected without the need for cabling between the alarms. Instead, a radio signal is used to trigger all the alarms in the system. 2. Which alarms can be used with radioLINK? The Ei141, Ei144, Ei146, Ei161, Ei161R, Ei164, Ei164R, Ei166 and Ei166R smoke and heat alarms can all be used with an Ei168 base to make a RadioLINK system. These all require a mains supply to them.
7. Will security systems and car alarms affect the smoke alarm system? Security systems may use the same frequency as the RadioLINK but they will normally be on a different band and/or be restricted to using the channel for 1% of the time, for a maximum of 4 seconds at any one time. Also, the unique code used by RadioLINK units means that interference is a very remote possibility. Car alarms and mobile phones use a completely different frequency so interference is not possible from either of these.
12. Are the RadioLINK units kitemarked to BS 5446:Pt.1? BS 5446: Pt.1 is the standard that smoke alarms should be Kitemarked to. As the Ei405 and Ei405TY are smoke alarms, they have been 3rd Party tested and Kitemarked to this standard. The Ei168 RadioLINK base is not a smoke alarm; it is a base that a smoke alarm is attached to. Consequently, this standard is not applicable to the Ei168. 13.
17. Is there any method of controlling a RadioLINK system? A fixed wall switch, Ei411, is available. This allows Test and Locate features to be incorporated into a RadioLINK system without having to reach up to the alarms. The switch is the same size as a normal light switch and is powered by Lithium cells having a realistic 10 year life. This means that the switch is easily installed, as it does not require any wiring, the signals to the alarms being transmitted by a radio link.
