Care And Maintenance - Tyco VIZOR EDPA Manual

Care and
Maintenance
The TYCO VIZOR Electronic Dry Pipe
Accelerator must be inspected and
maintained in accordance with the
NFPA. The following test procedures
must be performed in addition to any
specific requirements of the NFPA.
Any impairment must be immediately
corrected.
Before closing a fire protection system
main control valve on the system that
it controls, obtain permission from
the proper authorities to shut down
the affected fire protection system
and notify all personnel who may be
affected by this action.
In accordance with the requirements of
NFPA 25 and 72, one of the trip tests
described in this section must be per-
formed quarterly. Battery tests also
described here must be performed
semi-annually and annually.
The VIZOR Accelerator uses electronic
components to monitor the system air
pressure. Keep all radio transmitters
or RF sources at least one foot from
the VIZOR Accelerator. Failure to do so
could result in an unintended operation
of the dry pipe system.
Notify the proper authorities and all
personnel who may be affected before
temporarily disabling the VIZOR Accel-
erator or performing an alarm test.
The VIZOR Accelerator must be in a
normal condition for 60 seconds before
conducting a trip test. Failure to wait 60
seconds after air pressure has reached
the normal level will result in a failed
test.
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 (e.g., NFPA 25 and 72),
in addition to the standards of any
authority having jurisdiction. Contact
the installing contractor or product
manufacturer with any questions.
Automatic sprinkler systems are rec-
ommended to be inspected, tested,
and maintained by a qualified Inspec-
tion Service.
Full Flow Trip Test: Valve and
Accelerator
Step 1. Open the Inspector's Test Con-
nection. Verify that the VIZOR Accel-
erator trip-time is essentially the same
as in previously performed tests. Also,
make sure that the following notifica-
tions occur (Ref. Figure 1):
• Red Tripped LED lights
• Amber Trouble/Supervisory LED
flashes 4 times per second (fast)
• Buzzer sounds
• High/Low Contacts transfer
Step 2. Verify that the dry pipe valve
tripped and that the time for water
delivery to the Inspector's Test Con-
nection is essentially the same as in
previous tests.
Step 3. After verification of water deliv-
ery to the Inspector's Test Connection,
close the system's Main Control Valve
and reset the system.
Partial Flow Trip Test: Valve and
Accelerator
Step 1. Close the system's Main
Control Valve and then open the sys-
tem's Main Drain Valve to relieve the
supply pressure to the dry pipe valve.
Step 2. Partially open the system's
Main Control Valve at least to the point
at which water can be heard flowing
though the system's Main Drain Valve,
and then slowly close the system's
Main Drain Valve.
Step 3. Additional turns may be nec-
essary to ensure latching of the appro-
priate dry pipe valve; refer to the
appropriate technical data sheet.
Step 4. Open the Inspector's Test Con-
nection. Verify that the time-to-trip for
the VIZOR Accelerator is essentially the
same as in previous tests. A momen-
tary burst of air from the dry pipe
valve's automatic drain valve indicates
that the VIZOR Accelerator has tripped.
Also, verify that the following notifica-
tions occur (Ref. Figure 1):
• Red Tripped LED lights
• Amber Trouble/Supervisory LED
flashes once per second (slow)
• Buzzer sounds
• High/Low Contacts transfer
Step 5. Verify that the dry pipe valve
tripped and waterflow alarms operate.
Step 6. Immediately after verification
of the dry pipe valve trip, close the sys-
tem's Main Control Valve and reset the
system.

No Flow Trip Test: Accelerator Only
Step 1. Close the system's Main
Control Valve and then open the sys-
tem's Main Drain Valve to relieve the
supply pressure to the dry pipe valve.
Step 2. Open the Inspector's Test Con-
nection. Verify that the time-to-trip for
the VIZOR Accelerator is essentially the
same as in previous tests. A momen-
tary burst of air from the dry pipe
valve's automatic drain valve indicates
that the VIZOR Accelerator has tripped.
Also, make sure that the following noti-
fications occur (Ref. Figure 1):
• Red Tripped LED lights
• Amber Trouble/Supervisory LED
flashes once per second (slow)
• Buzzer sounds
• High/Low Contacts transfer
Step 3. Reset the system.
Battery Tests
Perform the following tests to verify
that the batteries are connected and
working and to verify battery levels.
• Battery Connections
Perform this test semi-annually.
1. Open the Battery Housing and un-
plug the Batteries from the VIZOR
Accelerator circuit board.
2. Verify that the VIZOR Accelera-
tor registers battery trouble and
sounds the internal audible alarm.
3. Press S2 to the Silence position.
4. Plug the Batteries back into the
VIZOR Accelerator circuit board
and close the Housing.
5. Verify battery trouble clears.
• Battery Levels
Perform a battery load test annually.
An alarm-and-detection technician
can perform this test.
