Arming The System - Accurex XRRS Series Installation, Operation And Maintenance Manual

Arming the System

NOTE
System arming is typically performed by factory
authorized fire equipment distributor during startup.
Do not tamper with the fire suppression system after
the initial startup unless authorized to do so.
To arm the range, do the following:
1. Once hood and hood components are installed,
wired, and fan is balanced (if necessary), drop the
hood into the service position, (instructions on page
22) and turn on all breakers feeding the hood and
hood components.
2. Remove the black cover from the fire suppression
control board enclosure inside the hood (on left side
of hood if looking at the hood front face).

3. With the cylinder pull-pin still installed in the agent
tank (mounted beneath the fire suppression board),
and 9V battery installed on the fire suppression
control board, initiate a diagnostic test by press
and release of the "TEST" button (also on the fire
suppression board).

4. The test should fail and issue six chirps, indicating
that the pull pin has not been removed from the tank.
If the result is a lesser number of chirps followed by
the series of six chirps, then some item other than
the pull pin has failed and the system should be
troubleshot before proceeding further (see Diagnostic
Failure Codes, page 25).
5. After troubleshooting, re-test until only the 6 chirp
diagnostic failure code occurs.
6. Verify that the fuel shut-off is powered (breaker is on)
and all burners on the range are off.
7. Remove wing screws that hold
the fire suppression control
board enclosure in place above
the wet chemical tank. Without
disconnecting any cables, slide
the control board assembly
towards the middle of the hood
and down so it's next to the tank,
revealing the tank assembly.
8. Check and make sure the solenoid release latch
is engaged and holding the release latch up, then
remove the pull pin from the agent cylinder and insert
the pull pin in its socket on the PCU board.
