2. Using the ICP-B6 as a Telephone Zone
When the ICP-B6 is used as a telephone zone
module, the 24 VDC provides supervision,
trouble, and call-in conditions. If the 24 VDC is
lost, the trouble condition INPUT DEVICE
RESPONSE TOO LOW displays at the MXL/
MXLV and an LED for that zone lights at the
VSM-1 module.
The supervised telephone common talk riser
starts at the TBM module in the MME-3 back-
box. The Class B shielded cable connects
continuously to each ICP-B6 with a 5.6K end of
line device. Tie the shield of these riser wires
and the shield of the zone output wires together
using terminal 5 of TB2 and isolate them from
the system circuits and the earth ground.
Connect the supervised individual zone output
connections from each ICP-B6 to the field
telephone with shielded cable. Terminate
them at the last station with a 10K ohm end of
line resistor. As with the common talk line
described in the paragraph above, be sure
that the shield is continuous and isolated

3. Using the ICP-B6 as a 70 Volt Speaker
Zone
When the ICP-B6 is used as a speaker zone,
the 24 VDC provides the supervision. If the 24
volts is lost or there is an open or shorted
speaker output line, the trouble condition
INPUT DEVICE RESPONSE TOO LOW
displays at the MXL/MXLV and the related
zone LED on the VSM-1 lights.
The 70.7V RMS audio input comes from the
amplifier via the ASC-2 Amplifier Supervision
card. The ASC-2 supervises the audio con-
nection path to the ICP-B6 and provides up to
100 watts of power. The ASC-2 can be used
as Style Y (Class B) or Style Z (Class A). Refer
to the ASC-2 Instructions, P/N 315-092085.
When the ICP-B6 is used as a speaker zone,
the output speaker lines are supervised and
power limited. The audio output cannot exceed
