When the HCP is used as a speaker zone (FireFinder-XLS System only), the 24 VDC
provides power to the supervision circuitry. If the 24 volts is lost or there is an open
or shorted speaker output line, a trouble condition displays on the PMI/PMI-2 of the
FireFinder-XLS.
The 70.7V/25V RMS audio input to the HCP must be power limited, such as from the
ZAC-40. The ZAC-40 supervises the audio connection path to the HCP and provides
up to 40 watts of power. The ZAC-40 can be wired Style Y (Class B) only. Refer to the
ZAC-40 Installation Instructions, P/N 315-035400 for further information. In order to
function properly during degrade mode, the DLC to which the HCP is connected
must be located in the same enclosure as the DAC-NET and ZAC-40 that supply
audio to the HCP .
When the HCP is used as a speaker zone, the output speaker lines are only super-
vised when the zone is not active. The audio output must not be allowed to exceed
25 watts. The approximate decibel loss for the total speaker zone wire length for
various wire gauge sizes is shown in Figure 7 for the 70.7V option and in Figure 8 for
the 25V option. Connect the speaker output as Style Y (Class B) as shown in Figure 9.
