Specifications

Pre-Programmed Modes

• Activation of Z-6 turns NAC-1 and NAC-2 steady.

• For the use of the system for pre-action, deluge releasing applications.

• Acceptable, Approved solenoids for the FR-320 are listed in Appendix B.

• Secondary power supply must provide for minimum of 90 hours of standby

operation followed by 10 minutes of releasing and alarm operation. See

Appendix E for Power Supply and Battery Calculations.

• Minimum secondary supply voltage for this application is 21.1 VDC. In order to

maintain required operating voltage at the solenoid, wiring lengths must not be

as such as to exceed the maximum line resistance value of 1 Ohms at a

maximum load of 1A.

• Initiating device circuits must be Class A for this application, thus necessitating

use of the ICAC-306 Class A Converter Module.
