Product Overview

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. Please could you tell me how long it takes to charge up the battery on the Kidde radio interlinked bases?
A.

Hello, it takes 24 hours to fully charge the back up battery on the Kidde radio interlinked bases.

Q. I installed several KE1SFWRF, KE2SFWRF and KE3SFWRF wireless mains-powered smoke alarms. After installation of the 'master' and the 'slaves' the alarms flash every ten seconds. Is this correct?

Also, when carrying out a test pressing the 'master' test button, the 'slaves' beep for varying periods and sometimes seemingly endless. Pressing the hush button does not silence them quickly.
A.

Flashing lights:
The RF bases have visual LED lights on the sides which show the status of the bases. The green LED on the Master RF base will go out for a second once every ten seconds and the Remote RF base green LED goes out for only half a second every ten seconds. This shows normal operation.

The smoke or heat alarms themselves have a green LED light which is constantly on when the mains power is connected. They also have a flashing red LED which shows normal operation. This typical flashes once every 30 to 35 seconds showing normal operation or flashes rapidly when in alarm state.

Testing and silencing the 'slaves':
The hush button on the 'slaves' only reduces sensitivity of the alarms (eg if you have burned some toast and the alarm goes off). It does not switch off the test sequence of the 'slaves' after you pressed the 'master' test button. This test sequence will continue for differing periods, which can be several alarm cycles long.

Q. Does this alarm conform to BS 5446 part 1 as recommended by the Fire Service?
A.

This recommendation has been superseded by BS 14604:2005. All of our smoke and heat alarms conform to this standard in accordance with the Kitemark.

Q. My ceiling light is on a dimmer switch. Can I still power my radio-interlinked mains smoke alarms from this lighting supply?
A.

In modern housing the lighting circuit will travel around your house with the lights being fed from it. Between the circuit and the light will be a switch (or in this case a dimmer) which will control the light. Your mains powered alarms are connected directly to the circuit and have constant power, so are not affected by switches or dimmers.
In older homes that have not had the electrics updated this may not be the case so it is advisable to consult an electrician.

Q. Can the mains powered smoke alarm range be connected to mains power via the lighting circuit?
A.

Yes, hard-wired mains powered alarms can be wired to the unswitched live feed of the nearest frequently used lighting circuit.
