86rac manual

I have two BRK 86RAC Ionisation type smoke detector, one in the Hall and the other on the upstairs Landing, these were installed by the builder and in I added a heat detector MBX in the garage, all three devices are mains powered with battery backup and are interlinked so that they all alert to a detection.

Checking the batteries in the smoke detector I noticed the unit has a life of 10 years from date of manufacture which was 21 June , as the date of noticing this was 4 March , they are well overdue for replacement!

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 from the base to allow me to take photographs of the wiring.

Once the cable colours were recorded, the detector was unpluged and the base completely disconnected to allow the replacement of the new base, once this was screwed into place, the connections were remade. The wiring in the base looks more complicated than it should due to the change of cable colours, the existing 1mm CSA 3 core and earth used the pre EU harmonisation wire colour convention of Red, Yellow and Blue, the cable to the new additional detectors which I have installed are in the office and IT cupboard, uses harmonised colours of Brown, Black and Grey, as the installation has mixed wire colouring, a warning notice to this effect is fixed 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 in the base, this is a safety feature. After making the connections, the detector base was fixed to the surface fitting by two supplied screws, the cardboard sealing gasket was then pressed into place covering the detector base fixing holes, the next step was to plug the lead into the base of the detector and lastly twist the detector into the base.

Within the baseplate of the detector is a small plastic extrusion which can be removed, this is used once the detector is installed as a locking clip preventing the detector being removed from the base with the clip in place.

With all detectors connected and new ones installed, mains power was turned back on, and each detector was then checked that it showed a continuous green LED for power healthy and a flashing red LED every 60 seconds to show the detector is functioning. The center test button on each detector was pressed and held, this caused the local unit to sound, followed a moment later by all the other interconnected heads.

I've removed all of the units, and there is still beeping happening apparently from the wiring, even though that doesn't make any sense. Interconnected units may provide earlier warning than stand-alone units since all units alarm when one detects smoke. Ionization smoke alarms are generally more effective at detecting flaming fires which consume combustible materials rapidly and spread quickly.

Sources of these fires may include paper burning in a wastebasket, or a grease fire in the kitchen. Photoelectric smoke alarms are generally more effective at detecting smoldering fires which smolder for hours before bursting into flame. Sources of these fires may include cigarettes burning in couches or bedding.

If you are installing this smoke alarm for use by others, you must leave this manual—or a copy of it—with the end user.
