THE FIRE PANEL ENCLOSURE
The panel is supplied with a plastic detachable lid, a plastic back box and a minimum of two separate PCBs.
The relative location of these PCBs is indicated in figure 1 below.
The panel can be surface or semi-flush mounted. It must be installed indoors, positioned to avoid accidental
damage, and not subject to conditions likely to affect its performance, e.g. dust, conductive or corrosive
gases or liquids, nor subject to temperatures, input voltages and electrical loads outside the stated operating
range. It should be sited at a height where it is easily accessible and in a prominent position within the
building. Ideally, the indicators on the front of the enclosure should be at eye level and the ambient light
level should allow the status of the indicators to be clearly seen.
Typical locations for the panel are in the entrance foyer/hallway of a building at ground floor level (the first
and most obvious point of contact for emergency services) or a security office that is likely to be permanently
manned.
Removing the lid and base PCBs
To protect the electronics from damage and to expose the base mounting holes, the panel’s lid and PCBs
should be removed prior to first fix installation.
Anti-static handling guidelines
Please ensure that the following electro-static handling precautions are taken immediately
prior to handling the panel’s PCBs or any other static-sensitive components:
Before handling any static-sensitive items, operators should rid themselves of any personal electro-static
charge by momentarily touching any sound connection to safety earth, e.g. a radiator.
Always handle PCBs by their sides and avoid touching the legs of any components.
PCBs should be stored 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.

Figure 1 : Location of the panel’s base PCBs and removal details
1. Take the fire alarm panel out of its box and undo the two lid screws using the Torx key provided.
Remove the lid to expose the Main Control PCB (the Power supply PCB is located underneath).
2. Carefully remove the five retaining screws on the Main Control PCB and slide the PCB up and over the
mounting pillars, taking care not to damage any of the components.
3. Disconnect the telecoms-style connecting cable at PL1 on the Power Supply PCB, making sure that the
cable remains connected to the reverse of the Main Control PCB to prevent it being misplaced. Care
should be taken when detaching this connector to depress the locking tab to prevent damage.
4. Pull the Power Supply’s earth distribution strap off the spade connector at the base earth distribution post.
5. Carefully remove the three retaining screws on the Power Supply PCB and slide the PCB up and over
the mounting pillars, again taking care not to damage any of the components.
