Flooded Basement / Cellar Pump Alarm with Battery Backup
|
Delta
High Level Alarm (mains dependent / mains independent)
An audible high-level alarm to warn of mains power or pump failure
within a pump station. The alarm is normally powered by 240v
mains voltage, however in the event of mains failure the unit
automatically switches to the battery back-up situated within
the unit. The 12v battery, which is continually trickle charged
is built into the control panel circuit and is designed to last
for life. The system operates via a fl oat switch fitted within
the chamber, normally fastened to the pump handle, and is connected
to the control panel that is normally situated within 8 metes
of the pump chamber in a dry environment.
The alarm is also fitted with a ‘test’ switch to
allow routine checking of the system without the need to enter
the sump. A special option is also available with volt free
contacts so the unit can be
wired to give a remote signal i.e. building management system
or separate audible / visual alarm.
