Installation

For full Installation and Siting Instructions please refer to the Installation Instructions and User Instructions

Ideally install in the centre of ceiling at least 300mm(12”) from light fittings. Interconnect all alarms

Ensure live mains is correctly connected to brown Smoke Alarm wire on the interconnected alarms – otherwise units will be damaged

Do not fit actual alarm until all building work is completed to avoid contamination. After checking operation, cover smoke alarm with dust cover until required for use

Don’t megger the alarm. Disconnect the alarm before applying high voltage to house wiring

Trouble Shooting

Frequent nuisance Alarms occur:

Close kitchen/bathroom door when in use

Ensure that the alarm is sited at least 6m away from sources of fumes

Contamination from insects, paint or paint fumes may have occured. Clean the alarm

If the problem persists, resiting of the unit should be considered. Alternatively, replace the unit with an Optical unit, assuming that the problem is with an Ionisation type alarm

Alarm sounds for no apparent reason:

Identify the alarm source. On all interconnected units, the red light under the test button or on the cover will flash rapidly only on the unit which is the source of the alarm

Check for fumes, steam etc. from the kitchen or bathroom. Paint and other fumes can cause nuisance alarms

Press the hush button on the Ei151TL and Ei150. On the Ei151TLH and Ei155H press the combined test/hush button

If the alarm does not stop, switch off mains and remove unit.(only remove alarm with red light flashing, the others are probably satisfactory)

Alarms beeps continuously:

Alarms may be in ‘hush mode’. Press the test button for 10 seconds to reset the unit (Ei151TL or Ei150 only)

Cells may be flat due to mains failure (Ei151TL, 154TL, 156TLH only). Check the green mains light is on. If not, check fuse, circuit breakers and wiring connections

If the above fails to turn on the green light, a fault may exist. Switch off mains and remove the unit, or press the hush button on the Ei151TL/150 or press the combined test/hush button on the Ei156TLH/155H

If the green mains light is on and the action in (bullet point 1) above has not silenced the beeping, a fault may exist. Remove the unit

Interconnected Alarms do not all sound:

Hold test button for 10 seconds after first alarm has sounded to ensure signal is transmitted to all units

Switch off mains and check that live, neutral and interconnect cables have been correctly connected and that connections are tight
