Viking Sprinkler Release Zone
System Types
Release Zone
OUTPUTS
(Indicating Circuits)
#1 General Alarm
#2 Supervisory Bell
#3 Release Solenoid
#4 N/O Solenoid
Inputs: 1 FIRECYCLE Detector zone, 1 Low Air Alarm zone, 1 Waterflow zone, 1 Manual Release zone, 2
Supervisory zones
Outputs: 1 General Alarm, 1 Supervisory Bell, 1 Release Solenoid, and 1 N/O Solenoid
Operation: Simultaneous activation of both the FIRECYCLE Detector zone #3 and the Low Air alarm zone #4 will
activate output #1 (General Alarm), output #2 (Supervisory Bell), output #3 (Release Solenoid), and
output #4 (N/O Solenoid).
Activation of FIRECYCLE Detector zone #3 will activate output #1 (General Alarm)
Activation of Low Air Alarm zone #4 alone will activate output #2 (Supervisory Bell) and output #4
(N/O Solenoid)
Activation of Waterflow zone #5 will activate output #1 (General Alarm) and output #4 (N/O solenoid)
Activation of Manual Release zone #6 will activate output #1 (General Alarm) and output #3 (Release
Solenoid)
Deactivation of FIRECYCLE Detector zone #3 will start soak timer, when timer cycle is complete the
output #3 (Release Solenoid) is deactivated.
Activation of Low Air Supervisory zone #1 or Valve Tamper Supervisory zone #2 will activate output #2
(Supervisory Bell)

Release Outputs which are Cross-Zoned need a Software Zone in order to work properly. The Software Zone Number will be displayed
upon a release.
XX = Cross-Zoned
NOTES:
1. Connect EOL Diode assembly IN SERIES as shown with Solenoid on output #3 (Release Solenoid) and output #4 (N/O
Solenoid). Black wire to negative terminal on panel and Red wire through Solenoid to positive terminal on panel.
2. Polarity is shown on indicating circuits in an activated (in alarm) condition.
3. Install EOLR (provided) on all unnused circuits.
4. See the instruction manual for circuit information, panel limits, and battery sizing.
5. For wire routing instructions through the releasing panel, see Fig 1 on page 2-7 of the instruction manual.
6. See instruction manual for proper programming.
7. See specific system type data page for proper pressure switch settings.
8. Connect EOL resistor after last FIRECYCLE detector on return line to common terminal in FIRECYCLE Detector zone #1.
9. Set the soak timer to desired duration period. Factory setting is continuous. Recommend 60 seconds minimum.
10. Loss of DC power below 20 volt causes output #3 (Release Solenoid) to drop out.
11. Use only Viking FIRECYCLE detectors on FIRECYCLE Detector zone #1.
12. Refer to Viking technical data sheet F_051304 for Firecycle double interlock multi-cycle operation.
13. For UL864 Approved Programming Options, see page 6-102.
