Kidde's Slick wireless optical smoke alarm 2SFW (previously 2SF23/9hi) has the unique fast fit base and screwless terminals (each alarm still needs connection to a local lighting circuit but interconnecting is wireless) and a simple fitting for the smoke alarm to slot-in fit. Installation or removal for maintenance takes a fraction of the time compared to a hard-wired alarm making the ideal for large housing projects, listed buildings or for those places where wiring is difficult. This 230V alarm becomes wireless with the simple addition of the wireless base. It can even be tested or hushed with the optional remote control.

Standard features include green and red LEDs as indicators, separate hush and test buttons, auto reset afer activation, latching LED to identify the initiating alarm and up to 6 months operation on the backup battery in the event of mains failure.

The Slick 2SFW (formerly 2SF23/9hi) is the optical smoke alarm version (or photoelectric) for detecting smouldering fires and is suitable for bedrooms, living rooms, offices, etc and is less prone to nuisance alarms from kitchens or bathrooms. The Slick wireless can be mixed with Kidde Slick, Kidde CO and Kidde Firex hard-wired alarms.
Optical alarms are suitable for smouldering fires and are to be used in hallways, bedrooms, and offices - a house should have a combination of optical and ionisation
Do not use in or too near to a kitchen or shower room
Fixing requires two little screws and wallplugs (included) to screw to ceiling and connection into a local lighting circuit with the screwless terminal blocks.

Inter-connecting the alarms is wireless when using the wireless base option for each alarm

    Good product, very comprehensive instructions. Standard pattern fixing screws with pozi 2 heads would be better.

    Not being in the trade I ran through the website working out what I needed. All the information was there. I rang to confirm that everything I needed was correct and this was confirmed. I ordered and was immediately called back to say that one of the parts wouldn't be available until the end of the week. This didn't matter to me. But before the end of the week everything arrived. Excellent service. It's not been installed yet but I'm sure it will be fine.
