b) Refer to BS7671 (Requirements for Electrical Installations) or other appropriate local standards for guidelines on
maximum potential cable lengths given the actual installation parameters.

!
1) Excessively large RJ45 cables will not fit the strain relief guides. RJ45 plugs with excessively bulky rubber boot will
not fit the connectors on the MPS properly; see cable and rubber boot dimensions in Figure 1 (page 8).
Suitable CAT5 patch leads are supplied with the microphone (ASL P/N 208440).
2)
Emergency Microphones that are used as location for display of mandatory EN 54-16 indications and controls
should have dual power supply: one power supply connected to ROUTER 1 port, and the other power supply
to ROUTER 2 port.
3) Headset microphone cannot be used in emergency mode.
4) For EMC compliance:
•
Screened cables must be used where specified.
•
All screen tails must be less than 3 cm.
