When using an external power supply unit, the failure of the mains supply, or the
failure of the batteries, charging system, or fuse, can be reported to the ZP3 fire
panel as shown below. The power supply unit must incorporate two sets of
voltage-free contacts, one which changes over on mains failure, the other which
changes over on battery fault (disconnected battery, low or high voltage, etc.),
charger failure, or fuse failure. These contacts must be connected to the ZP3
main board terminals as shown in Figure 41 on page 54. When the contact
changes state, the fault is reported to the ZP3 panel, which indicates the
appropriate visual and audible alarm, as well as signalling to the remote manned
centre.
