Operation:
NOTES:
1. Connect EOL Diode assembly IN SERIES as shown with solenoids on outputs #3 and #4. Black wire to negative terminal on
panel. Red wire through solenoid to positive terminal on panel. Output #3 has 2 solenoids. These must be connected in parallel
and the EOL diode is connected in series with the parallel solenoids.
2. Polarity is shown on indicating/release 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 instruction manual for list of compatible smoke detectors and solenoids.
8. See specific system type data page for proper pressure switch settings.
9. Connect EOL resistor in SERIES after LAST Firecycle detector on return line to common terminal in Firecycle detector
zone #1.
10. Set the soak timer to desired duration period. Factory setting is continuous. Recommended time is 60 seconds, minimum.
11. Loss of power below 20 volts causes output #3 (release solenoids) and output #4 (N/O solenoid) to drop out.
12. See Viking technical data sheet F_051404 for Firecycle deluge multi-cycle system.
13. For UL864 Approved Programming Options, see page 6-102.

OPERATION DESCRIPTION
1 Firecycle Detection zone, 1 Low air alarm zone, 1 Waterflow zone, 1 Manual Release zone,
2 Supervisory zones
1 General Alarm, 1 Low Air/Tamper, 2 Release Solenoids (single output from panel), 1 N/O
solenoid
Activation of Firecycle Detection zone #3 will activate output #3 (release solenoids), output #1
(General Alarm), and output #4 (N/O solenoid)
Activation of Low air alarm zone #4 will activate output #2 (Low air/Tamper) 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 #3 (release solenoids) and output #1
(General Alarm)
Deactivation of the Firecycle Detector Zone #3 will start soak timer. When timer cycle is
complete, output #3 (release solenoids) is deactivated.
Activation of Valve Tamper supervisory zone #1, Low air supervisory zone #2, or Low air
alarm #2 will operate output #2 (Low air/Tamper)
