APPENDIX C
Installation Of The MF9300 Control Panels
General Points:
Before actually installing your MF9300 panel please note the following points about the system:
The wiring for each of the zones and alarm lines is to be a 2 core parallel circuit with the end of line
resistor fitted to the end of the circuit. No 'spurs' or 'tee offs' are permitted. The wiring diagram (Fig.3)
gives more details.
If a zone is not to be used at all then the end of line resistor must be left in the relevant zone terminal
blocks in the panel.
All equipment used must be of the open circuit type.
Manual call points used in the system (MBG913/MBG914) are polarised. Use the connection details
accompanying the manual call points in order to ensure that the correct polarity of connections is
observed at all times. Also, make sure that the 'MF9300' terminals are used on the manual call
points.
All cables should be tested for Earth fault before connection to the panel. Do not use a MEGGER on
any cable after connection to any equipment including the fire panel.
The maximum load permitted on each of the 4 alarm sounder circuits is specified in the Technical
Specification (Appendix D, fig.4). The load should be spread equally across the circuits. All sounders
must be polarised, with the correct polarity of connections being observed at all times. Refer to the
wiring diagram (Appendix D, fig.3) and the instructions with the relevant sounders for the appropriate
connection details.
All cables entering or leaving the panels must do so via the 'knock-out' positions provided.
Additional Instructions for Electromagnetic Compatibility
When used as intended this product complies with EMC Directive (89/336/EEC) and the UK EMC
regulations 1992 (SI 2372/1992) by meeting the limits set by the standards BS 5406 (Pts 2 & 3)
1988, EN50082-1 1991 and EN50081-1 1992. The following installation guidelines must be followed.
1. External cables must be connected using the cable entries or knockouts provided.
2. When routing external cables inside the product they must be
a) Kept as short as possible
b) Routed close to the housing
c) Kept as far as possible from the electronics
Any modifications other than those stated in this manual, or any other use of this product may
cause interference and it is the responsibility of the user to comply with the EMC and Low
Voltage Directives.
Installing The Panel:
Follow the steps shown here, in conjunction with the assembly diagram shown in this manual (Fig.1):
1. Unscrew the battery cover plate and the centre section from the back box and place the centre
section somewhere safe. Take the back box and remove/drill any knockouts that are to be used,
either on the top or rear of the enclosure. Note that specific knockout positions should be used
for the AC mains supply. These positions are indicated both on the back box itself and on the
assemly diagram (Fig 1) Note also that the cables should only enter or leave the enclosure via
positions indicated by the knockouts. Do not drill additional holes in the enclosure. Fix the back
box to the wall. Use the 4 fixing holes in the back of the enclosure if it is to be mounted proud of the
wall. Alternatively, for flush fixing, use the 5mm mounting holes 4 off around the lip of the erar
enclosure to mount the panel.
