WIRING:
• Loop-wired system with multi-conductor shielded cable.
All-master system: 4 common wires + 1 wire per number of stations in the system.
If All Call is included: Add 4 additional common wires (P1~P3,Y).
If Door Release is included (LEF-5/10/10S): Add 1 common (L) + 1 individual wire
for each door to be released (K# terminals).
Single-master system: 2 wires homerun* from each sub to the master.
Leave jumpers between E & – installed.
*NOTE: It is recommended even in a single master system that 3 wires are used for
all sub stations in the system, and that the E & - jumpers are removed. This ensures
that the wiring is proper in the event of system expansion in the future.
Intermixed system with masters and subs: 3 wires from each sub to the nearest
master, or 2 common + 1 individual wire per station on a loop. Remove jumpers
between E & – from all stations in a multi-master system.
