4.13 Noise and Interference

The Z14 contains a microprocessor. Extreme electrical noise can upset
microprocessors. The most likely cause of such noise is the high voltage output from
the unit itself. In the event of erratic behaviour, check that the high voltage wiring is
firmly connected to the terminals and that no sparking is seen. The Z14 is designed
to self-recover from interference. Powering off (both AC and battery) should not be
necessary.

4.14 Programmable Options

The Z14 has many programmable options. These are also known as setup
parameters. To alter these options, a keypad must be used. The options are
explained in Programming Options In Brief on page 24. Each parameter has a factory
set default.

4.15 Low Power mode

Z14 energizers can be switched into Low Power mode. Low Power mode may be
used in situations where the fence is not required to be a deterrent but is still required
to actively detect intrusion. In Low Power mode the fence live wires operate at a
much lower voltage, typically 500V peak. See Programming Options in Brief on page
24 for details on using the keypad to set Low Voltage mode.

4.16 Key Switch

The unit may be armed using the key switch on the right-hand side. Alternatively, if
a keypad is fitted, it may be armed from the keypad. An external switch device, for
example a remote receiver or access control keypad, can also be used to arm and
disarm the unit.

4.17 Gate Input

The gate input may be wired to a gate switch to trigger an alarm when a gate is
opened. Alternatively, it may be programmed as a control input for Low Power mode.
This is determined by the programmable option settings but defaults to Gate Switch
mode.
If the unit is disarmed, the gate input may be set to Chime mode. If the unit is in Low
Power mode, the gate input may be programmed as Chime mode or Alarm mode.
See Programming Options in Brief on page 24.

4.18 Group Simultaneous Pulse Feature

In some installations it may be preferable to provide the ability to link multiple units
into a group. When linked, the individual Z14s, Z18s and Z28s become a group.
As many as fifteen energizers can be grouped. Individual units in a group have
