External Power Supply (AC Supply)
The power supply has a three-way terminal block for Live, Earth and Neutral
connections, and is protected by a 20mm anti-surge fuse. Mains earth is isolated
from the 0v output, although, when supplied boxed, mains earth is connected to the
metal enclosure.
Tamper Output
This voltage free output is connected to the Tamper Switch. These terminals will be
shorted when the tamper switch is closed.
24V Power Output
Terminal blocks are provided to connect to the system. The “ON” LED indicates
that 24V is available from these terminal blocks.
Auxiliary Power Supply (Batteries)
These power supplies are compatible with 7AH or 8AH Sealed Lead Acid or Gel
batteries which are connected to the “BATT” terminals.
If two batteries are to be used, they must be connected in series.
