NOTES
1. Loop resistance 50 ohms
Max with 252 devices on
the loop. Refer to the FS-
250 Manual, P/N 315-
049353 if the number of
devices is less than 252.
2. 12-18 AWG wire.
3. No EOL device required.
4. Supervised, power limited
per NEC 760.
5. All wiring must conform
to national and local
electrical codes.

HCP
When performing a loop test with the DPU be sure to apply power to the HCP .
Without power applied to the HCP a blinking "C" will appear on the DPU, indicating
that the HCP is in trouble.
This application uses the principle of polarity reversal to activate notification appli-
ances. Wiring is shown in Figure 4. Connect the HCP output zone wiring to the (+)
and (-) terminals of each notification appliance as shown in Figure 4. For a list of
compatible devices, refer to P/N 315-096363.
When used as a NAC module, the 24VDC provides power for the supervision circuitry
and to the notification appliances when they are activated. The power source must be
power limited. See the HCP Power Supply section (above) for compatible power sources.
The maximum output load that may be connected to an HCP is 1.5A at 24 VDC. If the 24
VDC is lost or the NAC line is broken or shorted while the HCP is in supervisory mode, a
trouble condition displays at the FireFinder-XLS, FS-250 System control panel, the Desigo
FC2025/2050, FV2025/2050 Operating Unit, and the Cerberus PRO FC922/924, FV922/
924 Operating Unit. For FS-250 Systems, the NAC circuit must be set to "always on" in
the panel or FS-CT2 configuration tool. See the Line Resistance table below for the
allowable line resistance for each HCP output circuit.
