CAST ZFP Analogue Addressable Fire Alarm Panel
5.2

Mounting Location

Each panel must wall mounted, indoors and positioned to avoid accidental damage, and MUST NOT be subjected
to excessive dust, conductive or corrosive gases or liquids, nor subject to temperatures, input voltages and electrical
loads outside the stated operating range. They should be sited at an easily accessible height and in a prominent
position within the building. The ambient light and sound levels should allow the indicators and touchscreen to be
clearly visible and the internal buzzer clearly heard. 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 in a permanently manned
security office.
5.3

Removing the Lid and PCB Chassis

To protect the panel's electronic components from damage and also to expose the back box mounting holes,
the panel's lid and PCB chassis should be removed prior to initial installation. Note: The PSU should not be
removed.
All removed panel components should be stored in a clean, dry place which is free from vibration, dust and
excessive heat.
Hint! Retaining the components in a suitable cardboard box will also guard them against mechanical
damage.
To remove the lid:

Use the supplied key to unlock the lid (key number 801).

Open the lid 180° to the left (do not overbend the hinges), then disconnect the lid's earth strap.

By hand, or by using a screwdriver, push out the lid's two plastic hinge pins (shown right)
and lift off the lid.
To remove the PCB chassis:
See 'Anti-static handling guidelines' in section 1.3

Disconnect the earth strap from the PCB chassis. Remove the four retaining screws that secure the PCB
chassis in the back box and carefully remove the chassis to expose the PSU.
5.4

Planning the Cable Layout in the Panel and Removing Knockouts

Mains wiring should be segregated from extra low voltage field wiring. Leave sufficient tails
inside the panel to ensure straightforward connection of wiring to the panel's terminals.
All cables should be fed into the panel through the knockouts provided in the back box.
Knockouts should be removed with a sharp, light tap using a 6mm flat-bladed screwdriver
as shown in the diagram (right). Ensure any swarf is removed from the enclosure.
Always ensure if a knockout is removed, the hole is filled with a good quality 20mm strain
relief, cable gland. Any unused knockouts must be securely blanked off.
5.5

Wall Mounting the Back Box

Note: The panel can be surface or semi-flush mounted on a wall (note optional bezels are available for semi-
flush mounting).
CAUTION: The enclosures are heavy! Therefore, use suitable screw fixings for wall mounting
the enclosures.
Securely fix the panel to a vertical wall, ≤2m mounting height, using the four (
provided in the back box. The mounting holes are suitable for use with countersunk screws.
See Appendix 1 for enclosure fixing details.
Always assess the condition and construction of the wall and use suitable screw fixings for the in-service weight
of the product. Any dust or swarf created during the fixing process must be removed from the inside of the back
box. Ensure there is sufficient space to allow the lid to be fitted / removed when the panel is wall mounted.
