7.1 Power Options

The Z14 has 2 sources of power, 16VAC and 12VDC (Battery).
NOTE: Use only rechargeable batteries. Always ensure adequate ventilation is
available for the housing if it contains a battery. Lead acid batteries may emit explosive
gases while charging!

If an error occurs, an Output assigned to General Alarm will go into alarm state.
Minor errors will self-clear if the error condition is removed.
Mains fail will not disarm the energizer, nor will low battery. However, without mains
power, the battery will eventually be depleted and the energizer will attempt to
maintain operation by entering low power mode after 4 warning beeps. If the battery
charge continues to fall, the energizer will eventually stop. Once mains power
has been restored and the battery has recovered, the energizer will re-arm itself
automatically after 4 warning beeps.
A PCB fault will disarm the Energizer. If an error disarms the Energizer, the General
Alarm and Fence Alarm will be activated.

7.3 Jumpers

The Z14 has two special purpose jumpers (links). These are listed in the table below.

Purpose
Fit J3 to inhibit mains fail errors if the intention
is to operate the Z14 on DC only (as in Solar
Power systems)
If the energizer needs to be defaulted to
factory settings, remove all power – mains and
battery – and remove the J4 jumper. Reapply
the battery power first, and then the mains
power. Reapply the J4 jumper and the unit
will be reset to default settings. If Status LED
flashes four times after defaulting the unit, return
it to the nearest JVA service centre.
