The Mini-Gens must be connected to the ANC3 relay output since this is
the only one with sufficient current rating and suitable supervision. This
relay can be configured for full supervision of up to three branches of
loudspeaker wiring, using the 27k ELDs provided with the MX1.
Do not use the 9k or 18k ELDs as they are not suitable for use with
100V lines.
All Mini-Gens must have their 2W supervision link fitted. If all three
branches of wiring are not used, the extra 27k ELD resistors must be
connected across the last Mini-Gen’s DC terminals.
An ISO 8201 Strobe Driver Module (PA1043) can be fitted instead of a
Mini-Gen to drive T3 synchronised strobes.
When the Alert and Evacuation tones must be separately controlled by
the MX1, one of the GP OUT terminals can be connected to the Mini-
Gen’s Alert input, as shown in the diagram. This is not default operation,
and the MX1 must be specially configured.
