* For use with Twinflex Pro & Twinflex V3 Checkpoint Plus Control panels only. The setting will be ignored on older systems without Checkpoint
Plus. With Logical Link enabled the sounder in that device only will operate during the Alarm Confirmation period, and with the Logical Link disabled
all the sounders in the same zone as the device in alarm will operate during the Alarm Confirmation period.
** Not Approved to EN54-7.
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 already 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 (V3 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. On the Twinflex Pro panel, the common 'Fault' LED will be on, the buzzer will sound and the system indication 'zone LED
will flash at approximately twice the rate of the buzzer. The display will indicate FAULT 00x OF 00x & Z0x: Zone description and
fault type.
Replacing Contaminated Optical Chambers
The optical chamber within the detector is not user serviceable. When an optical chamber becomes contaminated we recommend
replacing the detector. Cleaning an old chamber is not possible with this device as it is a sealed unit. It is essential that the location
of the contaminated device is verified using the device LED which will flash once approximately every 1.3 seconds
Beacon Operation (Not EN54-23 Compliant)
The Multipoint ASD may also incorporate a sounder or beacon (ignore all references to sounders / beacons if your device has no
sounder / beacon). If the unit includes a Beacon this consists of a number of high output LEDs mounted beneath a diffusing lens at
the lowest part of the detector.
The beacon will start to operate when the device receives a command to activate its sounder, even if the sound pattern is set to
SP0 - Sounder off. Thus, it is possible for the beacon to provide a discrete warning by setting the sound pattern to SP0.
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.
