CAST XFP 16 ZONE ANALOGUE ADDRESSABLE FIRE ALARM PANEL

INSTALLATION AND WIRING

The fire panel enclosure

The panel is supplied with a plastic detachable lid, plastic back box, Main Control PCB and a Power
Supply 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, 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, 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).

Removing the lid and base PCBs

CAUTION: ISOLATE THE PANEL'S MAINS AND BATTERY SUPPLIES BEFORE REMOVING
THE LID AND BASE PCBs.
Undo the two lid screws using the key provided. Remove the lid to access the Main Control PCB
•
(the Power Supply PCB is located underneath).
Carefully remove the five retaining screws on the Main Control PCB and slide the PCB up and
•
over its mounting pillars, taking care not to damage any of the components.
Disconnect the telecoms-style connector cable from PL1 on the Power Supply PCB, making sure
•
that the cable remains connected to the rear of the Main Control PCB to prevent it being misplaced.
Pull the Power Supply's earth distribution strap off the spade connector at the base earth
•
distribution post.
Carefully remove the three retaining screws on the Power Supply PCB and slide the PCB up and
•
over its mounting pillars, taking care not to damage any of the 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.
