SMOKE ALARM
If smoke detection system has been installed on your lift. It has
been designed to provide adherence to British Standard BS5900
2012 Section 9.13 “Behaviour of homelift in the event of fire”.
The system utilises two smoke alarms one upper level, one lower
level, which are wirelessly connected to the lift (see illustration
below).
The Smoke Alarm unit comprises two parts, the first (TOP PART)
being a Smoke alarm unit. This is the Smoke detection unit and
contains an integral battery with a 10 year life span. This is not
replaceable.
The second part (BASE UNIT) contains the radio transmitter
receiver unit. Power to this unit is supplied by two AA style
batteries. The voltage level of the batteries is monitored.
In the event of a low battery, a sounder in the carriage will beep
(see Fault Finding pg.20). If the batteries are not replaced, the lift
will be taken out of service.
Radio smoke alarm operation
When installed on a Harmony Lift, the smoke alarm system will
cause the lift to deactivate safely once the alarm is triggered.
When deactivated, the door will continue to operate as normal.
