MODULARM 75LC Multi-Monitor Installation & Operating
for the IP-1 from outside of the walk-in must be sealed both
on the outside and on the inside of the walk-in to prevent a
pathway for condensation.
Mounting the MD-1:
(Install in Coolers only). The MD-1 may be flush mounted
into a standard J-Box rotated 90°. A typical outdoor type
single gang outlet box may be used for surface mounting.
(NOTE: The MD-1 is a low voltage device. Wiring to the
MD-1 must not be installed in the same conduit as line
voltage wiring. A 6’ length of color coded installation wiring
is pre-connected to the MD-1). Typical mounting location for
the MD-1 is inside of the walk-in above the door. There is no
need to open or access the motion detector itself. Mount
the MD-1 horizontally with the white oval lens facing down.
The red light inside of the MD-1 will illuminate whenever
the MD-1 is activated.
WIRING: See Wiring Diagrams, page 10 & 11. Keep wiring
relatively short inside of the enclosure for the 75LC. Make
sure that wiring openings into all enclosures are sealed
properly to prevent a pathway for condensation.
Line Voltage Wiring:
The line voltage terminal block will accept up to 12AWG
wire. Wire the 3 line voltage connections in accordance
with the accompanying 75LC Connections diagram.
Connections are also marked on the 75LC.The stripped
end of the line voltage wire connections should be kept
short, approximately ¼” long. Insert the wire ends into
the appropriate terminal block openings and tighten the
screws securely to clamp the wires into place. With
stranded wire, make sure that all strands are captured
in the terminal block openings. Tug on wire to make
sure connections are secure. MAKE SURE THE SCREWS
ARE TIGHT! Supply connection wiring must be rated at
least 90°C. Use copper conductors only. Make sure that
the green wire from the 75LC faceplate is properly
grounded. If a metal enclosure is used for mounting
the 75LC, make sure that the enclosure is also properly
grounded.
Low Voltage Wiring:
The low voltage terminal blocks will accept wire from
24-16AWG. Accessories and sensors are typically provided
with 24-22AWG wire. General Accessories and sensor
connections are shown on the accompanying 75LC
Connections diagram. Connections are also marked on
the 75LC. See the diagrams labeled “IP-1 Connections”,
“MD-1 Connections”, and “IP-1 & MD-1 Connections”
for wiring specific to your application. The stripped end of
the low voltage wire connections should be kept short,
approximately ¼” long. To connect wires, press down on
the respective plunger on the top of the terminal block,
insert the wire into the respective hole and release the
plunger. Tug on wires to make sure connections are
secure and that they are grabbing bare wire and not
insulation. (NOTE: If the IP-1 and the MD-1 are both being
used, use the enclosure for the IP-1 as a junction box for
connecting the MD-1 in accordance with the “IP-1 & MD-1
Connections” diagram. Connect the green wires together
in the IP-1 enclosure with a wire nut or other connector.
Strip the 2 black wires approximately 3/8”, twist together
and insert both into the IP-1 block in accordance with the
diagram. Do the same with the two red wires. Again, tug
gently on all wires to make sure connections are secure.)
Temperature Probe Mounting:
Run the probe into the monitored compartment and locate
the sensor in a spot which will typify the average ambient
temperature. Recommended location is in the center of
the ceiling. Fasten the sensor with the provided clamp.
Make sure sensor and sensor wire are positioned and/or
protected so as not to be damaged by products or items
in the monitored area. (Seal any openings made for
passage of the probe wire into the walk-in on the inside
and the outside of the walk-in to prevent a pathway for
condensation.)
Magnetic Contacts Mounting:
Mounting method will vary depending on the type of
contacts utilized. Make sure that the operating gap
between the magnet part and the switch part of the
contacts accurately detects a door open or a door closed
condition. (The DOOR light is on constantly when the door
is open. This light may be utilized to assist in proper switch
and magnet placement.) NOTE: For compartments with
more than one door, multiple sets of contacts, wired in
series, may be utilized to monitor multiple door’s status.
Mounting the 75LC onto the enclosure:
Mount the 75LC onto the enclosure with the provided
mounting screws. If the 75LC is mounted onto an outdoor
type single gang outlet box, route all wiring away from the
battery when the 75LC is inserted. Inspect the installation
for compliance with electrical code, safety, sealing
against moisture and condensation, and test to confirm
that the Product and installation are operating properly
in accordance with these instructions. Periodic testing is
recommended to ensure continued proper operation.
Locking the keypad:
Enter programming menu, select password “10” and press
Lights (Prog) switch. Display reads “Set” then returns to run
mode. The keypad is locked. To unlock, proceed as above
using password “105”. The keypad is unlocked.
Resetting the 75LC to factory defaults:
Enter programming menu, select password “20” and press
LIGHTS Button. Display reads “Set” then returns to run
mode. The 75LC is now in factory mode.
