Site all equipment indoors in well-lit areas, free from obstruction. Site controllers in the control room or lobby, 1.4
metres above final floor level (FFL). Fit Type A (fire telephone) outstations in fire fighting lobbies and fire access points,
1.3 to 1.4 metres above FFL. Fit Type B (disabled refuge) outstations in disabled refuges, 0.9 to 1.0 metre above FFL.

Mounting

F U S E
Remove base PCBs before first fix installation to protect them and expose the base mounting holes. Wall mount the
3A fused spur
controllers, either surface or semi-flush. Fix the base securely onto a wall using No.8 round-head, or countersunk
screws. After mounting, remove any dust/swarf and re-install base PCBs. Ensure all connecting looms are refitted.

Wiring

4
See Fig 1 above for cable types. Install wiring in accordance with the relevant national, regional or local regulations (in the UK this is the IEE
N/O C N/C 0V +24 OP3 OP2 OP1
Wiring Regs BS 7671 and BS 5839 Part 1. Use enhanced fire-rated cables from the controlller to the Type A & B outstations and the power supply.

Test Extensions

12
Test all extensions for faults before terminating to the controller using a FITT EVC line tester (see component list above).
CAUTION: DO NOT use an Insulation Resistance Tester with any devices connected as they will be destroyed and the warranty will be void.
Fit Outstations & NC951 Interface
All screens connect
Maximum recommended cable distance to the outstations is 1 km, beyond which audio quality may degrade. For wiring and connection
to Earth terminal
details refer to Type A outstation instructions (Doc. No. DCM0003819) and Type B outstation instructions (Doc. No. DAU0302000).

Connect Extensions to the Controller

Do not connect extensions to the controller until they have been tested, fault-free and suitable cable glands fitted. Connect extensions
directly to the Master Exchange PCB inside the controller (see Fig 2 left). Connect screens to the earth terminal in the back of the enclosure.
