INSTALLATION AND WIRING
The fire panel enclosure
The panel is supplied with a hinged metal lid, metal back box and four separate PCBs (Main Control PCB,
Power Supply PCB, Switch & Indicator PCB, LCD PCB). Space is available inside the panel for the rated
capacity of VRLA backup batteries and an optional network driver card.
The panel MUST be installed indoors in an area that is NOT subject to conditions that are likely to
affect its performance, e.g. damp, salt-air, water ingress, extremes of temperature, physical abuse, near
sources of electromagnetic interference, such as high current machines, welding equipment, etc.
The panel should be sited at a height where it is easily accessible and in a prominent position within
the building. Ideally, its front panel indicators should be at eye level. Typical locations for the panel
are in the entrance foyer/hallway at ground floor level (the first and most obvious point of contact for
emergency services), or a permanently manned security office.
It is recommended that you remove the panel’s lid and base PCBs before first fix installation to protect
the electronics from damage (see Fig.1 below).

To remove the lid:
• Undo the two lid screws using the hex key provided.
• Hinge the lid 180° to the left (do not overbend the hinges) and remove the lid’s earth strap
spade connector.
• Disconnect the telecoms-style lid/base connector cable at the Main Control PCB.
• Disconnect the two-way lid/base connector cable at the Main Control PCB.
• Remove the four retaining nuts that secure the hinges and lift off the lid.
To remove the base PCBs:
• Disconnect the 10-way PSU loom at the Main Control PCB.
• Pull the Power Supply PCB’s earth distribution strap off the spade connector at the base earth
distribution post.
• Remove the PCB retaining screws located bottom left hand side of both PCBs.
• Slide the PCBs up and over their mounting pillars, taking care not to damage any components.
• Store the PCBs in a clean, dry place which is free from vibration, dust and excessive heat.
Retaining the PCBs in a suitable cardboard box will also guard them against mechanical damage.
CAUTION: ISOLATE THE PANEL’S MAINS AND BATTERY SUPPLIES BEFORE
REMOVING THE LID AND BASE PCBs.
