8. Powering the Panel
Never connect batteries before applying mains power first.
Ensure that the panel is free from swarf, wire ends, knockout blanks and any other debris.
Ensure that all cable connections to loops, sounder circuits and other inputs or outputs being used are correct
and that the wiring is formed tidily away from the surface of the circuit board before applying power.
The panel requires two 12 V 7 Ah sealed lead acid batteries. The batteries should be placed in the bottom of the
box with the terminals facing up and facing each other.
Batteries can be dangerous. Do not short the battery terminals to the enclosure or mounting plate. The polarity
of the battery connection should be checked carefully before proceeding.
Connect the batteries together first by fitting the battery link to the battery terminals nearest the back of the
enclosure.
Connect the red battery lead to the terminal of the left hand battery nearest the front of the enclosure and the
black battery lead to the terminal of the right hand battery nearest the front of the enclosure.
The supply from the battery is protected by a 3.15 Amp, 20mm glass fuse that will rupture if excessive current is
demanded from the battery by the control panel. This fuse is labelled F4 and is located on the underside of the
circuit board.
To replace the battery fuse, the power should be removed from the panel and the plate removed as described in
section 4. The fuse must be replaced with one of the same type.
Never connect batteries before applying mains power first.

Once all power connections are correctly made and power is applied, the panel is ready to start.
8.1. Configuration Data - Write Enable Switch
Panels have a memory “Write Enable” switch fitted. This switch is used to physically prevent the configuration
memory contents from being changed.
Before making any changes to the panel configuration, it is necessary to ensure that this switch is in the “Write
Enable” position. The “Write Enable” position is with the switch actuator set to the left in the direction of the
arrow under the switch.
When left in the “Write Enable” position, a notification message will be given on the Hydrosense ID display. This
warning message will disappear 1 minute after the switch has been turned off or can be cancelled immediately by
operating the front panel “Reset” button.
