TOTALPAC2 Integrated Fire Protection System
Deluge System - Programming & Field Wiring Diagram
FM-086G-0-38E
1- Remote Controlled, Pneumatic Release
The TOTALPAC2 Unit without control panel is factory wired for
the following configuration:
f Deluge System with Pneumatic Release
This T
OTALPAC2 Unit has been provided without an
Integrated Control Panel since its dry contacts are
supervised by a remote panel. Contractor should make sure
the control panel supplied to control this system complies
with the sequence of operation described in MECHANICAL
SECTION. The remote control panel shall also be Listed and
be compatible for supervising sprinklers supervisory and
alarm contact devices. Refer to FIELD WIRING DIAGRAM
for more details. Make sure the system will perform as
required and is tested to confirm it meets all requirements.
Note: All field wiring should be terminated in the contractor
junction box and terminals provided (TBA and TBB) as
shown on the FIELD WIRING DIAGRAM. No connection
should be made directly in the trim components as this
would void warranty and might prevent the normal
operation of the unit.
Operation – Deluge
When a fire occurs, at least one pilot head reaches its trip
point. The pilot line pressure is released and the pneumatic
actuator is then automatically activated. The system alarm
audible devices sound and, if desired, can be silenced
manually. The operation of a pilot head will allow the water
to escape from the priming chamber of the deluge valve.
The clapper of the deluge valve opens, filling the outlet
chamber and flooding the entire area covered by the open
sprinklers and/or nozzles, causing the closing of the
waterflow pressure switch contact. Water flow audible
devices and the water motor gong (if installed) will sound.
The sprinkler system will continue to operate until the main
water supply control valve is manually closed.
1. Pilot Line Air Pressure Drop
Any leak or opening in the system pilot line network which
allows supervisory air pressure to drop below 25 psi on
175 psi systems (45 psi for 250 psi systems) causes the
opening of the Low Pressure Switch contact.
2. System Manual Operation
Manual opening of the deluge valve by the operation of
the manual emergency release valve causes the water
flow switch to operate.
Note: The same sequence is obtained with the operation
of the alarm test valve, but the deluge valve is kept
closed.
3. Supervisory of the Valves
An abnormal position of a valve will cause the closing of
the Valve Supervisory Switch contact. Both the Water
Supply Control Valve and the optional Shut-off Valve are
supervised.
