ZC3-4AB Speaker Zone Wiring Diagram
NOTE:
A 2A, 250V fuse (P/N 105-292199) is included in the
fuse kit for applications where a single zone of up to
100W at 70.7V is required. Place this fuse in the clips
for the desired zone and connect the zone wires to
the appropriate terminals. When this fuse is
installed, the EL-410C/D amplifier that connects to
this zone cannot be used for any other zones.
25/70.7V RMS SPEAKER UNITS:
Any UL listed Fire Protective Signaling Speaker
rated 25/70.7V RMS may be connected to this circuit.
See Compatible Notification Appliances, P/N 315-
096363 for compatible speaker models.
