ZP3 Fire Alarm Control Panel Installation Manual
v
General warnings and precautions
Trained service personnel must carry out procedures in this manual.
The control panel is powered from a 230 VAC primary supply and from a 24 VDC
battery backup supply.
WARNING:
Electrocution hazard. To avoid personal injury or death from
electrocution, remove all sources of power and allow stored energy to discharge
before installing or removing equipment.
Primary supply
WARNING:
The power supply forms part of the main board assembly. This
assembly consists of a circuit board (incorporating the power supply), mounted
on a metal chassis, with the power supply covered by a metal enclosure. The
enclosure must not be opened, and non-authorized persons must never remove
the circuit board from the chassis. Very high voltage potentials exist on the circuit
board, and disassembling any part of the power supply could be dangerous to
field personnel.
Connection to the 230 VAC primary supply (+10%,
−
15%), must comply with
National wiring regulations. The wiring must be permanently connected to the
building wiring through a 10 A, 3-core cable, and a double pole 10 A isolation
switch.
The primary supply must be wired to the correct terminals as follows:
• Live = Brown
• Neutral = Blue
• Earth = Green/Yellow
Note:
The earth wire MUST be connected for each installation.
Cautions
• The incoming mains fuse only breaks the live connection.
• Dangerous potential remains on the incoming terminals even when the fuse is
removed.
• Dangerous potentials can also exist at other locations on the PCB even with
mains and battery disconnected.
