Power Up
The Multipoint detector requires approximately one minute on power up to boot up its processor and settle down to
normal operation. Do not test the detector during this time. Ensure that the Detector Head is installed when the
system is powered up otherwise a fault condition will be present.
Head Contamination Warnings
If a smoke detector becomes dusty
,
its operation is affected, either making it more prone to false alarms, or in rare
cases reducing its sensitivity. The Multipoint LED will flash once approximately every 1.3 seconds. At the control
panel, the common ‘Fault’ LED will flash, the buzzer will sound and the relevant ‘Zone Fault’ LED will flash at
approximately twice the rate of the buzzer.
Replacing Contaminated Detector Head
The Detector Head contains the optical chamber. When an optical chamber becomes contaminated we recommend
replacing it with a new item. Cleaning an old chamber will not give satisfactory results. Firstly investigate the control
panel indications as above, then check the devices in the relevant zone to locate the Multipoint detector indicating
‘Fault’.
Remove the Detector Head with the Head Removal Tool and replace it with a new one. The fault indication should
clear in 30-45 seconds and return to normal.
Testing
We recommend the use of suitable smoke test equipment such as the ‘No Climb’ SOLO 300 tester or an equivalent
product. Due to the fact that the smoke detection modes are all ‘thermally enhanced’, it may be noticeable that on
test the devices respond more slowly than may be expected. This is perfectly normal and is due to the fact that
during test there is no additional heat present to cause the sensitivity to be enhanced.
Smoke mode 3 requires that the concentration of smoke is kept up for a longer period to trigger the device into
alarm, so patience is required. Small regular applications of test smoke are best in order to avoid drenching the
detector as this may result in sticky residues being left behind.
