INSTALLING THE DETECTION NETWORK – MRM
To install the detector linkage, place a weighted object on the cable at the MRM, allowing a minimum of 3
inches of extra cable length for every detector in the network. Starting at the terminal detector, place the
linkage upside-down on the cable, run the cable over the rivet and through each of the four tabs as shown
above, insert the appropriate fusible link (see the design section for proper selection of fusible links) and turn
upright. Repeat these steps for each detector.
Each link and link holder, once assembled and placed on the
cable, should be positioned in the bracket on center or slightly
off center away from the MRM.
To set the tension on the cable, first make sure that the
tension bar in the MRM is in the “down” position and that
the spring is relaxed.
WARNING: DO NOT ATTEMPT TO SET THE TENSION
BAR IN THE UP POSITION (SPRING
STRETCHED) WITHOUT HAVING A
FUSIBLE LINK LINE INSTALLED AND
SECURED OR THE MRM WILL FIRE
.
WARNING: CONDUIT MUST BE SECURED WITH
APPROPRIATE ANCHORS AT DISTANCES
NOT TO EXCEED 3 FEET. FAILURE TO
SECURE CONDUIT PROPERLY MAY
CAUSE SYSTEM FAILURE
.
Note: Early models also had a 3:00 and 9:00 position
which CANNOT be used
.
Insert the connector at 12:00 if the cable enters the MRM
at the TOP or 6:00 if it enters at the BOTTOM.
NOTE: Any excess cable must be secured out of the
way of any parts in the MRM. We suggest taping it to
the link line cable.
Slip the set-up/lock-out tool (P/N 12738) over the manual
pull cam housing until it rests against the outside edge of
the collapsible linkage. (See adjacent illustration) Draw
tension on to the cable through the connector until the link
plate is drawn against the set-up tool, then tighten the set
screw on the connector.
Remove the set-up tool and raise the tension bar to test
cable run. Lower tension bar until system is ready to test.
To test the detection network, refer to the testing and
commissioning section.

Link Plate Connector
P/N 12732
Attach the cable to the link plate connector, do not clamp tightly
(slack must be taken up in a later step). Insert the connector
into the slot on the link plate that corresponds with the direction
of pull on the cable. The link plate is marked with clock
positions (6:00 and 12:00).
