3 Installation
3.1 Installing the Enclosure
Unlock the front door and remove the ferrite absorber and EOL resistor kits. Store these in a
secure place for re-use later.
If removing the chassis prior to installing the back box, proceed as described below.
3.1.1 Removing the Chassis
Unplug the ribbon cable between the CPU Board and the Display Board at the CPU Board end.
With ZX10Se panels you need to do this for each of the ZX5Se panels.
Remove the nuts and spring washers holding the chassis to the back box. There are four of each
for ZX1Se / ZX2Se, six of each for ZX5Se and twelve for the ZX10Se. Store these in a secure
place for re-use later.
For the ZX1Se/2Se panels only, disconnect the internal wiring from the AUX, Sounders and Relay
connectors at the bottom edge of the Base PCB. DO NOT disconnect the wiring at the Filter PCB.
Refer to Section 3.4.14 Cable Routing for correct wiring termination after chassis remounting.
Carefully remove the chassis assembly. Store in a secure place where it will not be damaged
and where it will be kept dry and clean.
Handle the chassis by holding the metalwork only. DO NOT lift it by holding the printed
circuit boards or any parts on the circuit boards.
3.1.2 Mounting the Enclosure to the Wall
The ZX5Se Fire Alarm Control Panel can weigh in excess of 39kg (ZX5Se) and 18kg (ZX2Se)
with the batteries fitted. When attaching the enclosure to a surface, use mounting hardware
capable of supporting this weight and reinforce the wall if necessary.
The ZX10Se can weigh
in excess of 76.8kg with two 24Ah batteries fitted.
Remove the necessary knockouts for the installation cabling.
Mount the enclosure in the desired location using all four mounting holes (the ZX10Se has 5 holes).
Use a drill bit diameter 7.0 mm and a suitable 40 mm long expansion plug. Fix the panel to the wall with
No. 10 screws length 1½” or M5 screws length 40 mm. DO NOT use countersunk-headed screws.
Install the external wiring into the enclosure using the appropriate glands / conduit fittings.
Sufficient knockouts are provided at the top of the enclosure. If you punch other holes, be sure
that they do not interfere with any component mounting positions.
Use a brush to clean any dust and swarf from inside the enclosure before attempting to remount
the chassis assembly.
For details of knockout positions, refer to Section 3.4.14 Cable Routing. Cables must be
megger tested before any active devices are fitted and before the connections are made to
the terminal blocks.
3.1.3 Remounting the Chassis
Carefully mount the chassis on to the threaded studs.
Make sure that the wiring between the Base PCB connectors and Filter PCB is not trapped
behind the chassis metalwork (the wiring is secured to the back box side wall to assist with this).
Secure the chassis to the back box using the nuts and spring washers that were originally removed.
Plug the ribbon cable between the CPU Board and the Display board back into the CPU Board.
The plug and socket are polarised to ensure correct insertion.
