REMOTE MOUNTING THE KEYBOARD
DISPLAY MODULE (FIG. 16)
1. The Keyboard Display Module can be mounted ei-
ther on the face of a panel door or other remote locations.
NOTE: A DATA CONTROLBUS MODULE™ or an Ex-
tension Cable Assembly is required to connect RM7888A
to a remote Keyboard Display Module.
2. When mounting the Keyboard Display Module on
the face of the door panel, closely follow these instructions:
a. Select the location on the door panel for flush mount-
ing. Pay attention to the insertion dimension of the two
Keyboard Display Module screws, two interlocking
ears and the two plug-in connectors to allow for suffi-
cient clearance (1/4 in. [6 mm] minimum) inward from
the surface of the door panel.
b. Use Fig. 30 as a template. Mark the two screw loca-
tions, two interlocking ear locations and the two
plug-in connector locations. Drill the pilot holes for
the mounting screws. Provide for two holes on the
door panel for the interlocking ears and two holes for
the plug-in connectors.
c. Mount the Keyboard Display Module on the door
using two no. 4 screws.
3. When mounting the Keyboard Display Module on a
wall or remote location, use part number 203765, Remote
Mounting Bracket.
a. Using the Remote Mounting Bracket as a template,
mark the four screw locations and drill the pilot holes.
b. Mount the Remote Mounting Bracket using four no.
6 screws.
c. Mount the Keyboard Display Module by aligning the
two interlocking ears with the two mating slots on the
Remote Mounting Bracket.
d. Insert the two interlocking ears into the two mating
slots. Push on lower corners of the Keyboard Display
Module to secure it to the Remote Mounting Bracket.
e. Make sure the Keyboard Display Module is firmly in
place.
INSTALLING THE PLUG-IN FLAME SIGNAL
AMPLIFIER (FIG. 17)
1. Disconnect the power supply before beginning the
installation to prevent electrical shock and equipment dam-
age. More than one disconnect may be involved.
2. Align the amplifier circuit board edge connector with
the keyed receptacle on the RM7888A. Make sure the ampli-
fier nameplate faces away from the Relay Module.
3. Push in the amplifier until the circuit board is fully
inserted into the receptacle and then push the amplifier
toward the RM7888A retaining clasp.
4. Make sure the amplifier is firmly in place.
5. Perform all required checkout tests.
