Care and
Maintenance
The following procedures and inspec-
tions should be performed as indicated,
in addition to any specific requirements
of the NFPA, and any impairment must
be immediately corrected.
The owner is responsible for the
inspection, testing, and maintenance of
their fire protection system and devices
in compliance with this document, as
well as with the applicable standards
of the NATIONAL FIRE PROTECTION
ASSOCIATION, for example, NFPA
25, in addition to the standards of any
authority having jurisdiction. Contact
the installing contractor or product
manufacturer with any questions.
It is recommended that automatic
sprinkler systems be inspected, tested,
and maintained by a qualified Inspec-
tion Service.
The Model QRS Electronic Accelera-
tor must be maintained and serviced
in accordance with this section.
NOTICE
The QRS uses electronic compo-
nents to monitor the system air pres-
sure. Keep all radio transmitters or RF
sources at least one foot from the QRS.
Failure to do so could result in an unin-
tended operation of the dry pipe or pre-
action system.
Before closing a fire protection system
main control valve for inspection or
maintenance work on the fire protec-
tion system that it controls, permission
to shut down the affected fire protec-
tion system must be obtained from
the proper authorities and all person-
nel who may be affected by this action
must be notified.
If an Accelerator is to be temporarily
taken out of service, the proper author-
ities and all personnel who may be
affected must be notified.
Model QRS Electronic Accelerator
Testing Procedure
It is recommended that the following
Accelerator test procedure be per-
formed quarterly.
Step 1.
When operation of the dry pipe/
preaction valve is not intended during
the Accelerator trip test, close the sys-
tem’s Main Control Valve and open the
system’s Main Drain Valve to relieve
the supply pressure to the dry pipe/
preaction valve. Otherwise, proceed
as follows.
Step 2.
For a dry pipe system, open the
Inspector’s Test Connection. Verify that
the time to Accelerator trip is essen-
tially the same as in previous tests.
A momentary burst of air from a dry
pipe valve’s Automatic Drain Valve indi-
cates that the Accelerator has tripped.
In addition, the display on the Operat-
ing Interface of the Releasing Panel will
indicate operation.
For a double interlock electric/elec-
tric preaction system, first operate the
detection system and then open the
Inspector’s Test Connection. Verify that
the time to Accelerator trip is essen-
tially the same as in previous tests.
Release of the DV-5
A
diaphragm pres-
sure though the open solenoid valve
indicates that the Accelerator has
tripped. In addition, the display on the
Operating Interface on the Releasing
Panel will indicate operation.
Step 3.
Reset the Model QRS Elec-
tronic Accelerator in accordance with
the appropriate Setting Procedure
section.
Releasing Panel and Batteries
Inspect, test, and maintain per the
instructions provided for the Model
PFC-4410RC Releasing Panel.
