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. Loss of power below 20 volts causes output #3 (release solenoids) and output #4 (N/O solenoid) to drop out.
10. See Viking technical data sheet F_051604 for Surefire single interlock operation.
11. For UL864 Approved Programming Options, see page 6-102.

OPERATION DESCRIPTION
1 Conventional 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 Conventional Detection zone #3 or manual release zone #6 will activate output #3
(release solenoids) and output #1 (General Alarm)
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)
Activation of Valve Tamper supervisory zone #1, Low air supervisory zone #2, or Low Air alarm
zone #2 will activate output #2 (Low Air/Tamper)
A trouble condition will prevent output #4 (N/O) from activating
