We recommend the use of 6243Y 3 core and earth PVC insulated cable to BS6004 standard. Building Regulations and BS 5839: Pt 6 state that mains only alarms with back-up, can be wired from a dedicated circuit at the distribution board, or they can be wired from a regularly used lighting circuit. In both cases, all hard wired alarms should be on a single final circuit.Aico Ei140 and Aico Ei160 series Smoke and Heat Alarms have an Easi-fit mounting plate,which incorporates an enclosure for the electrical connections, so no back box or mounting kit would normally be required.
20. Can I fit the Aico Smoke or the Aico Heat Alarm on the wall?All of the Aico Ei alarms are designed for ceiling mounting and will under most circumstances perform better if sited in this position. If it really is not practical to mount them on the ceiling, a Smoke Alarm can be wall mounted with the top edge 15-30cm from the ceiling. Ensure that it is 30cm away from any corner or obstruction which may impede the movement of smoke to the alarm. Do not wall mount heat alarms. Smoke and Heat Alarms should only be interconnected within the confines of a single family dwelling. If they are connected between different units, there may be excessive nuisance alarms and it can be difficult to locate and silence the unit causing the alarm. However, there is no technical reason why up to 20 alarms cannot be interconnected in a single system that encompasses a number of individual dwellings - such as may be required in an HMO, for instance. In circumstances such as these, a very high level of system design, management and maintenance is necessary to reduce the level of nuisance alarm.
The minimum requirement should be to install a System Remote Control Switch Ei1529RC on each floor of the property. By pressing the locate switch, all alarms in the system are silenced, for a period of approx. 8 - 10 minutes, except for the unit initiating the alarm state. This allows time to rectify the problem before the system is automatically reinstated to full working order.Aico 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. In addition, there are relays available with a battery back-up for use with devices that will operate even in the event of a mains failure, such as Warden Call Systems. The relay can be mounted under an alarm, or can be remotely sited using the optional cover for electrical safety. BS 5839: Pt 1 it may not meet all the requirements. For example, it is not possible to silence the sounder in the smoke alarm from the control panel. Many regulatory bodies now recognise that a dual system (smoke/heat alarms in the individual occupancies and a Pt.1 system in the communal areas) in HMOs can be an extremely effective means of reducing the incidence of false alarms. In this instance, subject to approval, it could be an advantage to have this link. BS 5839: Pt.6: 2004 recommends that a smoke/heat test is preformed when the system is commissioned. Pressing the test button checks the electronics, interconnect and the horn are operational, so it is our view that it is not necessary to test with smoke or heat and a ‘variation’ can be invoked in order to comply with the standard. However, if it is considered that testing of smoke alarms is a necessity, we would only recommend the use of special purpose built equipment such as the SAT332 Smoke Alarm Tester with the SAA300 Synthetic Smoke Aerosol. This device ensures that sufficient synthetic ”smoke” enters the sensor chamber and remains long enough for the Smoke Alarm to respond. Other methods of smoke testing, e.g. a lighted taper or smoke pellets, can give misleading results. Testers for Heat Alarms are also available. Do Not test with a flame - this can be a hazard in itself. Smoke Alarms and Heat Alarms are suitable for use in Grades D, E and F systems as defined in the British Standard which covers alarm systems in domestic dwellings, BS 5839: Pt6: 2004. It states that these alarms “should be cleaned periodically in accordance with the manufacturers instructions”. Our recommendations are as follows:
- Regularly check to see that the green mains power light is on.
- Press the test button weekly to check all alarms in the system.
- Regularly check that the red light under the test button or on the cover flashes approx. every 40 seconds.
- Clean the cover of the alarm regularly using a barely damp, lint free cloth.
- On a monthly basis (at least) check the alarm for signs of contamination from dust, cobwebs or insects. Use a vacuum cleaner around the cover of the alarm to remove contamination.
- Check (at least annually) that the alarm will operate on back-up battery power only by switching off the mains supply and pressing the test button.
31. What is the radiation risk from Ionisation Smoke Alarms?The National Radiological Protection Board (NRPB), UK have carried out extensive tests on Aico Ei professional Ionisation Smoke Alarms and have concluded that they are radiologically safe. They estimate that we receive 10,000 times as much radiation from our surroundings as we would from an ionisation alarm in normal use. Aico / Ei Electronics take their responsibilities to the environment seriously, and will accept redundant Ei product back for recycling/disposal. The Aico Ei140 and Aico Ei160 series do not contain NiCAd batteries, so are not subject to disposal restrictions.
34. Why choose Ei Professional/Aico Ei Smoke Alarms?Ei Professional Alarms are designed and manufactured by Europe’s largest producer of Smoke and Heat Alarms, with over 30 years experience in producing quality life safety devices.
