HCP As Telephone Zone
When the HCP is used as a telephone zone module (FireFinder-XLS System only) as
shown in Figure 5, the 24 VDC provides power to the supervision and call-in detection
circuitry. If the 24 VDC is lost, a trouble condition displays on the PMI/PMI-2 of the
FireFinder-XLS.
The HCP provides a dial tone when a Fireman’s Master telephone (FMT) is taken off
hook or when a Portable FireFighter’s telephone (PFT) is jacked in.
Each HCP can support a maximum of 5 phones off hook. Throughout the system, no
more than 10 phones may be off hook at any one time.
The supervised telephone common talk riser starts at the TZC-8B module in the CAB
backbox. The common talk riser connects continuously to each HCP with a 10K end
of line device at the last HCP. Tie the shield of these riser wires together using
terminal 5 of TB2 and isolate them from the system circuits and the earth ground.
Individual phones may not be connected to a riser that is wired to HCPs. The TZC-8B
zone must be configured for Riser usage in Zeus.
Connect the supervised telephone zone wiring to the HCP with twisted pair cable.
Terminate at the last station with a 75K ohm end of line resistor. As with the com-
mon talk line described in the paragraph above, be sure that the shield is continuous
and isolated from both system circuits and earth ground and that the shields are
connected together using terminal 5 of TB-2.
Figure 5
HCP Used As An NAC Module
The input power and NAC power inputs on TB2 (1-4)
must be connected to the same source.
All HCPs connected to a given DLC/FS-DLC circuit
must reside within a single notification zone.
