Kidde Slick radio-interlinked (RF) smoke alarms are mains powered from the nearest light fitting and come with alkaline battery backup batteries. The units use radio technology to 'talk' to each other: when one alarm activates, all other units that are interlinked via radio-interlink begin to alarm within seconds. The RF technology negates the need for connection wire, making the installation simpler and cheaper.

Q. Why do your mains powered alarms have batteries?
All our mains powered alarms have a battery backup. Although mains powered alarms without this option do exist (BS5839 part 6 grade E), we regard them as far too dangerous, as a lot of fires are caused by electrical faults leaving the building unprotected against fire if the smoke alarms have no backup battery. With our mains powered alarms you will always be protected.
Q. How can we test the alarm to make sure it is working?
The manufacturer's recommendation is to test the alarm by pressing the test button. This will simulate a heat input at the heat sensor. You can also test it with a hair dryer but make sure that the hairdryer is kept away at a suitable distance from the alarm. Do not attempt to test the alarm by using open fire or excessive heat as this may damage the unit.
Q. Do you need an electrician to connect mains powered smoke alarms?
It is necessary that an electrician installs mains powered smoke alarms.
Q. Can I expand an existing system of Kidde Slick mains powered smoke alarms (with existing interlink through cable) with additional Slick RF smoke alarms as shown in http://www.safelincs.co.uk/kidde-slick-wireless-smoke-alarms/?
Yes, you need to add an RF base to just ONE of the existing smoke alarms. Make sure you connect the existing interconnect cable into the slot marked 'i' on the new RF base. Then you can add new RF slick smoke alarms to the system. Just make sure you go through the 'enrolment' process again to ensure all units recognise each other.
Q. What sort of smoke alarm system would I need to install for a HMO?
BS 5839-6 recommends that one or two storey HMOs with an individual floor area of no more than 200sqm (not the total of both floors) should have a Grade D smoke alarm system installed. Grade D refers to mains powered smoke alarms with a back up battery power supply. The alarms can be interlinked either by wire or by radio signal and the system does not require a separate fire alarm panel. For HMOs of 3 storey or higher, a Grade A panel system would need to be installed. This can cover the whole of the building, or can be used just for the communal areas with a separate Grade D system installed for the individual dwellings. For both applications, the level of cover should be a minimum of LD3 (in all escape routes) but this may change according to the fire risk assessment.
