Interconnections Up to 18 units of First Alarm or BRK Smoke, CO and Heat Alarm. Maximum of 12 smoke detectors. See the manual for details. I have two BRK 86RAC ionization smoke detectors, one in the hall and the other on the landing, they were installed by the builder and in 2008 I added a heat detector (690MBX) in the garage, all three devices. are battery operated -Backup powered and connected so all alert on detection.

Checking the batteries in the smoke detector, I noticed that the unit has a life of 10 years from the date of manufacture which was June 21, 2002, as the date to note was March 4, 2002. 2018, I am long for the replacement!

Checked my local Screwfix had BRK ionization smoke detectors (part number 81969) for £12.99 and the surface kit (part number 30152) for £2.99, I thought I’d added two more to my system so bought four of everything

When I opened the boxes I didn’t realize that the detectors come with 9v PP3 type batteries so £6.00 was lost to buy and the other thing was that they are not a direct replacement, the 86RAC is basically a smaller size and the extra. Connector is another style.

In the box are the above instructions, a sticker for the consumer unit and a protective detector cover, no fixing screws are provided.

The first job was to isolate the mains supply to the existing detectors which are on their own dedicated circuit, once this was done I twisted the detectors off the base so I could take pictures of the wiring.

The existing wire was Black to Neutral, Brown to Vivid and Orange striped is the interconnect wire, 670MBX uses Blue for Neutral, Brown to Vivid and Gray for interconnect, the existing detector had a ferrite coil going through each wire of detector, while the new model does not have, decided to use these on the spare unit.

After recording the colors of the cable, the detector was removed and the base completely separated to allow the replacement of the new base, once this was screwed into place, the connections were redone.

The wiring in the base looks more complicated than it should due to the change in cable colors, the existing 1mm CSA 3 core and ground uses the pre-EU harmonized wire color convention of Red, Yellow and Blue , the cable to the new additional detectors. that I installed in the office and the IT cabinet, using harmonized colors of brown, black and gray, because the installation has a mixed wire color, a notice for this purpose is attached to the consumer unit.

While the new detector was on the desk, the battery was dated and connected, without a battery installed, the detector will not engage the base, this is a safety feature.

After the connections were made, the base of the detector was attached to the surface of the surface with two screws provided, the cardboard gasket was pushed into place covering the fixing holes of the base of the detector, the next step was the lead in the base that inserted the detector and finally. twist the detector into the base.

Inside the base of the detector base is a small plastic extrusion that can be removed, this is used after the detector is installed as a locking clip that prevents the detector from being removed from the base with the clip in the location

With all the detectors connected and set up again, the network was back on, and each detector was checked for a continuous green LED for full power and a flashing red LED every 60 seconds to show that the detector is working.

The central test button on each detector was pressed and held, this adds the local unit, followed a moment later by all the other heads connected.

I have already sealed the cables through the ceiling, the last work was to seal the base to the ceiling and paint the exposed part of the ceiling as the base is smaller than the original.

One point to note was that I used dry and circular power boxes to make the connections and hold the base, this would make the smoke detector fit closer to the ceiling, but it meant making a big hole, so I decided against it .
