In a large zone with multiple amplifiers across
several card cages, how can I get tone and
message synchronisation?
Use one amplifier in the zone as a "master" and configure all the
amplifiers for the same zone in other card racks as "slaves" - use an
ALIM modified per fig 3 of LT0372 to monitor the "master" amplifier's
100V line and feed it to the local audio input of the "slaves". "Slaves"
supervise their speaker line, but don't ever select anything but the local
input.
LT0372 (also PBQ0072 for
general ideas like this)
Installation Simplex® T3 Strobes not functioning
Simplex® T3 strobes only work on EVAC.
1) The Positive should be wired to Terminal B and the Negative should
be wired to Terminal A.
2) Dip switch setting (5, 6, 7, 8) have to be (OFF, ON, ON, ON)

Servicing
Comms light (yellow) is not flashing. One LED
(green) is flashing; 8-10V between comms. Panel
displays zones 3, 4 & 5 in Audio Fault. The panel has Faulty Strobe Card. After swapping two strobe cards
over, the fault cleared from the panel and followed the faulty strobe card
(when tested in another panel).
Servicing An Audio line fault is observed on Zones 2 & 3
After replacing the amps and transformers the fault still did not clear.
The ribbon cable may be at fault or damaged. The red ribbon should
point to pin number 1.
