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.

  • Mains Powered with alkaline back-up battery
  • Suitable for installations complying to BS 5839-6: 2019 Grade D2

FAQs (8)
Q. How can we test the alarm to make sure it is working?
A.

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?
A.

It is necessary that an electrician installs mains powered smoke alarms.

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

BS 5446-1:2000 was withdrawn in 2008 and replaced by BS EN 14604:2005 to conform with European standards. All of our alarms containing a smoke detector (smoke only, smoke & heat, smoke & CO) are fully compliant with BS EN 14604:2005. They also comply with any other relevant standards relating to their other detection capabilities.

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.
