the batteries, slide the battery assem-
bly into the housing, and plug the
harness connector into the VIZOR
accelerator circuit board.
For the optional 90-hour batteries,
mount the remote battery enclosure
horizontally and within 10 feet of the
VIZOR accelerator. Splice the battery
cable, see Figure 5, connect the cable
to the batteries, then plug the battery
assembly into the VIZOR accelera-
tor harness. Lastly, plug the harness
connector into the VIZOR accelerator
circuit board.
Step 4. Close and lock the cover.
Step 5. Push S1 to the OFF position.
Step 6. In order to minimize an inad-
vertent primary (A/C) power loss and
to facilitate maintenance, it is recom-
mended that a dedicated circuit be
hard-wired to the VIZOR accelerator.
The following notications occur:
•
The green AC LED lights, the amber
trouble / supervisory LED lights,
the red tripped LED lights, and the
buzzer sounds.
•
Assuming the batteries are charged,
the amber battery Trouble LED
remains unlit.
Step 7. Optionally conduct trip tests of
the VIZOR accelerator and the dry pipe
valve in accordance with the Care and
Maintenance section.
Step 8. Optionally, and/or if required
by local jurisdiction, hard-wire moni-
toring circuits to the Trouble and high/
low supervisory contacts using 14 to
18 AWG wire.
Step 9. Push S1 to the SET position.
Step 10. Verify proper operation of the
VIZOR accelerator using the “No Flow
Trip Test for Accelerator Only” proce-
dure described in the Care and Main-
tenance section.
Setting
Procedure
As soon as possible after an opera-
tion, reset and restore to service the
Dry Pipe Valve (listed in Table A) and
the TYCO VIZOR Electronic Dry Pipe
Accelerator in accordance with the fol-
lowing procedure.
NOTICE
Completely drain the system before
proceeding.
After setting a fire protection system,
notify the proper authorities and advise
those responsible for monitoring pro-
prietary and/or central station alarms.
Step 1. Push S1 to the OFF position.
Step 2. Silence the internal audible
alarm at any time by momentarily
pushing S2 to the SILENCE position.
Step 3. Locate all of the system’s low
point drain valves to help facilitate
resetting of the system. Refer to the
appropriate dry valve data sheet for
valve resetting procedures.
Step 4. Clean the strainer by removing
the clean-out plug and strainer basket.
Step 5. Follow the resetting procedure
for the installed dry pipe valve. When
the procedure calls for the system
piping to be pressurized with air, start
to pressurize the system and then
proceed to Step 6.
Step 6. When the system reaches an
air pressure of approximately 10 psi
and while the system is in the process
of reaching its intended pressure,
“blow-down” each drain valve. Be sure
to include the low body drains at the
dry pipe valve and the Inspector’s test
connection.
To “blow-down”, open each drain valve
individually, and when water stops
draining, close the drain valve. This
blow-down procedure assures that
complete draining of the system can
be more easily accomplished.
Step 7. When the system reaches the
normal intended air pressure, wait
approximately 30 seconds to allow for
stabilization of the air pressure within
the piping. Momentarily push button
S2 on the VIZOR to the RESET posi-
tion to clear the red tripped LED, and
then push button S1 the SET position.
Step 8. Open the inspector’s test con-
nection (ITC), verify that the VIZOR has
tripped. A momentary burst of air from
the dry pipe valve’s automatic drain
valve indicates that the VIZOR accel-
erator has tripped. Verify that the time-
to-trip for the accelerator is essentially
the same as in previous tests.
This procedure also clears scale and
debris from the pipe and ttings that are
connected to the VIZOR accelerator.
Step 9. Push S1 to the OFF position,
allow the system to automatically return
to its intended pressure via its auto-
matic air supply. After waiting approxi-
mately 30 seconds, momentarily push
S2 to the RESET position, and then
push S1 to the SET position.
Step 10. Partially open the main
control valve. Slowly close the system
main drain valve as soon as water dis-
charges from the drain connection.
Step 11. Depress the plunger on the
dry pipe valve’s automatic drain valve
to verify that it is open and that no water
discharges. The absence of water dis-
charge from the automatic drain valve
is an indication of a properly set water
seat within the dry pipe valve.
If water is discharging, see the Care
and Maintenance section within the
technical data sheet for the dry pipe
valve to determine/correct the cause of
the leakage problem.
If there are no leaks, fully open the
system main control valve.
The system is now set for service.
