Each time the MRM is fired the following procedures must
be performed to accomplish reset:
1. Remove cover of the MRM / MRM II and move the
tension bar to the “down" (relaxed) position. Move
the upper end of the blue spring into the lower end
of the spring slot.
2. Cock the MRM by simultaneously pushing in on
the lock spring and turning the “Cocking Tool”
counterclockwise. The mechanical pull piston
must be pushed in all the way.
3. Insert the set-up/lock-out tool after cocking.
4. If a nitrogen actuation cylinder was expelled, relieve
pressure from the actuation network by either
loosening a fitting or depressing the ball in the vent
check. Remove the nitrogen actuation cylinder.
5. Confirm that all detectors are assembled and fusible
links are properly installed.
6. Leave the set-up/lock-out tool in place and verify
that the cable for the detection network is properly
attached to the link plate.
NOTE: Refer to page 4-8 for MRM II
Detection Cable Adjustment.
7. Confirm that the manual stations have pull pins
inserted and tamper seals installed.
