QRS
QUICK RELEASE SWITCH
7. The EG terminal of the PFC-4410-RC shall be connected to a good
earth ground connection.
8. The AC power wires shall be kept away from all other wires
associated with the PFC-4410-RC by a minimum of 1 inch.
9. The shielded cable for the QRS shall be separated from the NAC
wiring by a minimum of 1 inch.10. There shall be no wires or circuits
allowed inside the PFC-4410-RC cabinet except those directly
connected to the panel. There shall be no external AC circuits brought
into the PFC-4410-RC cabinet.
11. The Top conduit entrances on the PFC-4410-RC cabinet shall
not be used if there is the possibility of condensation or other liquid
entering the cabinet.
12. The supervisory air in the system shall be set to match one of the
settings on the QRS rotary switch.
Testing the system
With power applied to the PFC-4410-RC panel and system pressure
corresponding to the setting on the QRS rotary switch, press the reset
button. The panel should restore to normal.
Wait 60 seconds before doing anything.
Note:
failure to wait 60 seconds before testing the system will result
in the system not operating properly!
Open the test valve, the QRS should operate and the panel should
display an alarm on the appropriate zone of the PFC panel.
Trouble Shooting Tips
Problem: PFC-4410RC indicates trouble on the zone the QRS is connected to.
Check: Temporarily remove all power from the PFC-4410RC for 5-10
seconds, then re-apply power. If power connections were made to the
QRS while the PFC-4410RC was hot, it may be necessary to reboot the
system.
Problem: System won’t trip when air pressure is dropped during test.
Check: Make sure a minimum of 30 seconds has expired after the system is
restored to normal pressure, the QRS has power applied and the PFC panel is reset.
The System air pressure and PFC panel must both be a normal
condition with the QRS powered up for a MINIMUM of 30 seconds
before the system can be tested.
Check: Troubleshooting tip #1 about rebooting the system.
Problem: The PFC panel indicates a SUPERVISORY condition.
Check: The system air pressure may not correspond with the rotary
switch setting on the QRS.
Adjust the system air pressure to match the rotary switch on the QRS.
(See the System Air Pressure Setting Chart on pg. 2)
Check: The system air pressure with calibrated gauges.
Problem: The system false trips or other unexplained operations.
Check: Was shielded cable used.
Check: Is the entire length of shielded cable completely enclosed in metal conduit.
Check: Is the drain wire connected to the S terminal of the PFC series panel only.
Check: Make sure the drain wire is not connected to the QRS.
Check: Make sure the cover is installed on the QRS.
Check: Make sure no wires other than the shielded cable for the QRS
are included in the metal conduit.
Check: Make sure the shielded cable is not running within 1” of either

If more than one QRS is used, install EOLR across
terminals 6 & 7 of the last QRS only. If only one QRS is used,
install EOLR across terminals 6 & 7 of QRS.
2
If more than one QRS is used, connect orange and yellow
wires to terminals 6 & 7 of all except the last QRS. If only one
QRS is used, do not use orange and yellow wires.
3
If more than one QRS is used, splice orange and yellow
wires from fi rst QRS to second QRS inside PFC Series cabinet.
Continue procedure to last QRS. If only one QRS is used, do
not connect orange and yellow wires at either end.
4
Shielded cable must be used. Alpha wire type 5198C or
equivalent. Cable must be installed in a continuous run of
metal conduit from PFC panel to QRS.
Reference wiring
diagram program #14
The QRS Quick Release Switch is to be wired to the Model PFC-4410-RC
releasing panel using shielded cable in metal conduit (rigid or fl exible).
Connect drain wire of shield to earth ground of the PFC-4410-RC only. Do
not connect drain wire to QRS.
Shielded cable: 6 or 8 conductor, 22 AWG stranded, PVC jacket, overall foil
shield with drain. (Alpha wire type 5198C or equivalent).
