12.3 HCVR-3 Connection Overview
12.3.1 Detection Zones and Notification Appliances
The HCVR-3 fire alarm control panel has three initiating device circuits (zones). Connect smoke detectors and
other initiating devices as indicated on the system design plans. Only compatible smoke detectors may be
used; see Appendix B of the
HCVR-3 Installation and Operation Manual
for details. Be sure to observe correct
polarity.
Figure 12.3.1 – Zone Connections
There are three notification appliance circuits (NACs) on the HCVR-3. NACs 1 and 2 are used to signal a
general fire alarm condition. NAC 3 is used to indicate one of two things; 1) the system is preparing to activate
the aerosol generators to discharge the extinguishing agent, or 2) the aerosol generators have already been
activated and the aerosol has been discharged into the compartment. The distinction between these two
different events is achieved in the way that the panel operates the output; when the release is imminent NAC
3 provides a pulsing output, but after the aerosol has been discharged the circuit provides a continuous output.
Because NAC 3 provides a pulsed output when the panel is counting down prior to activating the aerosol
generators, a strobe may not be used on this circuit.
See the
HCVR-3 Installation and Operation Manual
for more information about the zones and NACs on the
panel.
12.3.2 HCVR-SQA Sequential Activator
The HCVR-3 fire alarm control panel connects to one or more HCVR-SQA Sequential Activator modules. A
maximum of 20 HCVR-SQA modules may be connected to the HCVR-3 panel.
The HCVR-SQA connects to the EXTING circuit on the control panel. The End-of-Line Diode (EOLD) that
comes with the HCVR-3 panel must not be used with the HCVR-SQA. In addition, the HCVR-SQA requires 24
volt auxiliary power which is provided by the control panel. See Figure 12.3.2.
As shown in Figure 12.3.2, the last HCVR-SQA module in the circuit must have the termination jumper installed.
If only one HCVR-SQA is used, install the jumper on the module. In summary, one HCVR-SQA module shall
have the jumper installed and it must always be the last module on the circuit, even if only one module is used.
