MODULARM 75LC Multi-Monitor Installation & Operating
NOTICES
Before you start, please read these instructions
thoroughly in order to obtain maximum benefit from
the capabilities that this product offers.
Thank you for purchasing the 75LC multi-monitor. The 75LC
integrates sophisticated function with easy operation.
Patented Autoset*Technology, combined with common
pre-programmed default settings eliminates the need for
manual programming in most applications. PAS-PRO™
password programming allows for easy and secure custom
configuration. All product functions and accessories may be
used simultaneously or you may use only those required for
your application. A simple, 3 button user interface combined
with prioritized intuitive visual alarm display makes the 75LC
extremely user friendly.
OVERVIEW
75LC FUNCTIONS:
The 75LC offers the following functions: (Patented
Operation, other Patents Pending.)
1. HI & LO Temperature Alarm with Patented Autoset
Technology.
2. AC Failure Alarm with built-in rechargeable battery
and built in recharging circuitry.
3. Door Ajar Alarm. (Requires magnetic contacts. See
pg. 3)
4. Panic (Entrapment) Alarm (Requires optional IP-1
Illuminated Button See pg. 3)
5. Manual and patented timed light control.
6. HACCP monitoring. (additional equipment required)
7. Remote notification. (additional equipment required)
8. Built in audible alarm.
*What is Autoset?
Patented Autoset Technology selects the right alarm temp
setpoints for monitoring a cooler or a freezer automatically,
virtually eliminating the need for manual programming.
Common cooler and freezer setpoints are pre-loaded into
the 75LC. Autoset Setpoints are:
COOLER FREEZER
HI 42F (6C) HI 10F (-12C)
LO 30F (-1C) LO -20F (-29C)
Cooler setpoints are the default settings, used for cooler
monitoring. If the compartment is a freezer, Autoset
detects the lower compartment temperature and
automatically changes to the freezer setpoints. (Freezer
defaults won’t revert to cooler defaults if temperature rises.
Cooler defaults can be easily manually restored when
necessary.) Manually changing setpoints in the program
menu automatically disables Autoset.

MODULARM 75LC Multi-Monitor Installation & Operating
Using AutoPanic with an IP-1:
• If Autopanic is enabled, pressing the IP-1 at
any time while the door is closed starts the 20
minute Auto Panic Timer. When the Auto Panic
timer runs out, the IP-1 starts to beep and blink
for 40 seconds. Repressing IP-1 during a beep
and blink resets the Auto Panic Timer for 20
minutes.
• If not pressed, A Panic Alarm (HLP) automatically
annunciates on the 75LC to let others know that
someone may be injured or disabled inside the
walk-in. Auto Panic Alarm is cleared in the same
way as a Manual Panic Alarm.
Using AutoPanic with an MD-1:
• The MD-1 makes Autopanic easier to use. Each
time motion is detected, the MD-1 restarts the 20
minute Auto Panic Timer. If no motion is detected
for 20 minutes the IP-1 (if present) starts to beep
and blink for 40 seconds.
• If no motion is detected a Panic Alarm (HLP)
automatically annunciates on the 75LC to let
others know that someone may be injured or
disable inside the walk-in. Auto Panic Alarm is
cleared the same way as a Manual Panic Alarm.
AC Power Failure Operation:
• When power failure occurs: The 75LC will
alternate PF and the Monitored temperature
for 1 minute as shown above under “Abnormal
Condition”.
• For power failures under 1 minute: Normal
operation restores automatically and the incident
is ignored.
• For power failures beyond 1 minute: The
Alarm relay activates, and the horn will chirp
intermittently with a blinking decimal point.
Pressing Silence at any time during a power
failure silences the horn for 1 minute, and briefly
displays the monitored condition.
ACCESSORIES:
Three accessories expand 75LC operation:
1. IP-1 Illuminated Push Button
2. MD-1 Motion Detector
3. MC-1 Magnetic Contacts.
These accessories are low voltage devices, connected
directly to and powered by the 75LC. Accessories may
be used individually or in combination. To help eliminate
programming when common settings are desired, the 75LC
comes equipped with Autodetect.
What is Autodetect?
The Autodetect function in the 75LC senses if and when
an accessory is connected to the 75LC and automatically
integrates the connected accessory into device
operation. No special programming is required. The 75LC
ships with Autodetect enabled for the accessory inputs.
(Ex: If magnetic contacts are not connected, the 75LC
operates as if there are no magnetic contacts. Once
magnetic contacts are connected, Autodetect senses this
and automatically provides door ajar alarm function and
automatic lights on function when the door is open.)
Accessories Information:
• IP-1 Illuminated Push Button – The low voltage
IP-1 mounts inside of the walk-in and provides
both a lights control switch and a panic alarm
switch. (Press to control lights, press and hold
for 2 seconds to activate Panic Alarm “HLP”).
A buzzer and lights built into the IP-1 provide
warning to personnel in the walk-in that lights
may turn off if the IP-1 isn’t pressed.
• MD-1 Motion Detector – (Not recommended
for freezers) The low voltage MD-1 mounts
inside of the walk-in and duplicates the light ON
control function of the IP-1 button when activated
by movement of personnel inside of the walk-in.
• MC-1 Magnetic Contacts – Low voltage
magnetic contacts sense door status and
provide both a door ajar alarm switch and a
lights on switch relative to the status of the
door. One set of magnetic contacts come with
each 75LC, various styles are available.
OPERATION
LIGHT CONTROL OPERATION: The 75LC offers three ways
to control lights:
1. Regular timed lighting
2. Patented timed lighting with Auto Panic (default),
3. Untimed, manual on-off light control (replaces light
switches.)
Password selectable presets are used to easily change or
select the desired mode of operation for your configuration
(See pg. 6)
NOTE: The DOOR light blinks whenever lights are on.
1. Regular Timed Lighting Operation – When lights
turn on, the lights-off timer is activated. Lights will
turn off when the lights-off timer expires. Operation
is as follows:
• Without Accessories: Press the Lights Button
on the 75LC to turn lights on and start lights-off

timer. Press the Lights Button again to manually
turn lights off before the lights-off timer expires.
• With IP-1 installed: Press Lights Button or IP-1
to turn lights on and start lights off timer. Press
Lights Button or IP-1 Switch again to manually
turn lights off before the lights-off timer expires.
The IP-1 blinks and beeps for 40 seconds before
lights-off timer expires to warn personnel that
lights will be turning off. Pressing the IP-1 when it
is blinking/beeping resets the lights-off timer and
keeps lights on. If no action is taken the lights will
turn off when lights-off timer expires.
• With Magnetic Contacts installed: Open the
door to turn lights on. 75LC light button and
installed IP-1 will turn lights on & off with
door open. Once the door is closed the lights-off
timer will begin.
• With MD-1 motion detector installed: (Coolers
only) Activation of the MD-1 by movement of
personnel inside the walk-in turns lights on. When
personnel are no longer detected inside the walk-
in the lights turn off.
Any combination of accessories may be used.
Accessories operate together as described
individually.
2. Patented Timed Lighting with Auto Panic (Default) –
(Magnetic contacts required. IP-1 and/or MD-1
required in a cooler. IP-1 required in a freezer.)
Operation is as follows:
When the door opens, Lights turn on.Press the
75LC light button or installed IP-1 to turn
lights on & off while door is open. When the
Door is closed the Lights-off timer starts and the
IP-1 starts to beep and blink to prompt a button
press.
Pressing the IP-1 does the following:
1. Stops the lights-off timer and makes lights
stay on indefinitely for as long as the door
remains closed.
2. Starts a built-in 20 minute Auto Panic timer.
3. “Locks out” Light Switch on 75LC so that
someone outside of walk-in can’t turn off
lights while the box is occupied.
4. After 20 minutes, IP-1 starts to beep and blink
again for 40 seconds to prompt a “check in”
button press. Pressing the IP-1 resets and
restarts Auto Panic timer. This repeats for as
long as someone remains in the box with the
door closed. If IP-1 isn’t pressed within 40
seconds, the 75LC automatically generates
a panic alarm, “HLP” appears on the 75LC
display to let personnel outside the box know
that someone may be injured or disabled
inside of the walk-in.
5. Opening and closing door resets all functions.
If no one is in the box to press the IP-1 after
door is closed, lights turn off when lights-off
timer expires.
NOTE 1: With both Magnetic contacts and IP-1
installed, IP-1 is a Lights ON only switch when the
door is closed, and is a Lights ON/OFF switch when
the door is open.
NOTE 2: With the door closed, the IP-1 blinks and beeps
initially for 40 seconds and again for 40 seconds before
the lights-off timer expires. Pressing the IP-1 at any
time always activates the 20 minute Auto Panic timer.
NOTE 3: If door is closed and lights are off, the IP-1
always works as a “lights on” switch inside of the
walk-in and always activates the 20 minute Auto Panic
timer when pressed.
NOTE 4: In coolers, The MD-1 motion detector may
be used instead of or in addition to the IP-1. MD-1
activation duplicates an IP-1 press and automates the
process.
3. Untimed Manual On-Off Light Control – Replaces
standard light switches. Operation is as follows:
• Without accessories – Press lights button on
75LC to turn lights on. Press again to turn lights off.
• With IP-1 installed – IP-1 is a “lights ON/OFF”
switch inside of the walk-in. (Plus Manual
Panic Alarm)
• With Magnetic Contacts installed – Lights turn
on when the door is open. (Plus Door Ajar Alarm)
• With MD-1 installed – (Coolers only): Activation
of MD-1 by movement of personnel in walk-in
turns on lights.
Any combination of accessories may be used.
Accessories operate together as described
individually.

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
