Sensor Probe
The probes supplied with the Multi-Probe Alarm System are highly accurate temperature
sensors. The sensor may be put in water or other mild aqueous solutions from -100°C to 100°C.
NOTE: Avoid submerging the probe in solvents or harsh chemicals. Use protective thermowells
when monitoring such materials.

LMS Operating Manual Page 4
NOTE: The warranty does NOT cover damage to probes or electronics that is caused by
exceeding temperature limitations, or damage to probes caused by using them in solvents
or other unsuitable environments.
NOTE: If the displayed temperature shows a consistent high (> 100°C) or low (< -100°C) value,
most likely, the probe has failed.
Probe Installation
RTD sensors supplied with the LMS-188-4P should be installed using the supplied fittings,
which are 1/2” MNPT x 1/8” compression. After installing the fitting into a tee, insert the RTD
into the fitting and adjust the depth of the probe so as the tip of the probe is approximately at the
center of the piping. Tighten the nut finger tight, then with a small wrench turn the nut 1/4 to 1/2
turn past finger tight. Warning –do not overtighten.
Power-up

Alarm Conditions / Temperature Alarms
If the readings are within the alarm limits, the STATUS LED will blink green.
When the temperature reading meets or exceed the temperature limits the STATUS LED will
blink red.
After the probe’s alarm delay time is exceeded the unit will blink the ALARM LED and beep the
buzzer.
The user can MUTE the buzzer by tapping the MUTE/MENU button. The unit will reduce the
audible signal from a loud beep, to a quieter and less frequent chirp. It will remain muted until
MUTE time expires or a different probe goes into alarm.
Once the Alarm state has been signaled the unit will wait the appropriate Relay Delay(s) time
before tripping the appropriate Relay(s). Units with individual channel relays, have individual
Relay Delay times. Units with a single relay have one Relay Delay time that applies to any
alarm condition.

LMS Email Notification Feature
The LMS sends email on unit reset, alarm, continued alarm and recovery from alarm.
The unit sends email 5 minutes after email failure and repeats every 10 minutes after that.
Once daily, it sends a report of the last 24 hours that includes temperatures on the hour and alarms to
contact #1.
The email subject line identifies the unit and reports the current temperature. The message reports the
last 10 minutes of data. The unit is identified by the name ID001, where 001 is the unit number
assigned by the user as an LMS parameter. All mail settings are setup using web pages accessed by the
IP assigned to the unit.

ALARM DELAY MODULE (RDU Option)
INSTALLATION INSTRUCTIONS
I Description:
The Alarm Delay Module is designed to accept dry contact inputs, either Normally Open
(N.O.) or Normally Closed (N.C.), and to delay the transmission of the contact change
information to another device.
II Application:
The primary application is in alarm systems where it is desirable to insert a fixed time
interval between the detection of an alarm condition and the transmission of the alarm
information to monitoring systems, telephone dialers, external services, etc.
Such delay is particularly important in areas where short power interruptions are
frequent, or where transitory alarm conditions are likely to occur. The user can select a
time period of delay that results in the minimum number of "false" (self-correcting) alarm
transmissions while still providing the degree of safety required.
III Installation:
1. Remove the plastic case cover by removing the 2 Phillips screws from the
back. Apply light pressure on the face plate, the cover and face plate will
come off together.
2. Locate the ALARM INPUT switch on the circuit board. Move the switch
to the condition of the contacts in the alarm sending device when in the
NON-ALARM condition. The unit is shipped with the switch in the
N.O. (Normally Open) position, this will be correct for the majority of
installations, however, if your alarm device opens its contacts when it
alarms, simply slide the switch to the N.C. position.
3. Locate the row of pins on the short edge of the board labeled "minutes". A
shorting clip will be at the 8 minute position. In this position the alarm
delay module will require 8 minutes of CONTINUOUS incoming alarm
indication before sending the alarm status on to the next system. Move
the jumper to the set of pins marked either 0.5, 1, 2, 4, 8, 16, or 32
minutes, as your needs require. The pair of pins marked "T" are for test
purposes and should not be used.
4. Install the signal wires from your alarm. Route the wires through the
drilled hole at the bottom of the case and to the terminals marked 1 & 2.
5. Install the output wires to your output device, route the wires through the
drilled hole at the bottom of the case and to the terminals marked 4 & 5 if

12
it requires contact closure for operation or to terminals 3 & 4 if it requires
contact opening for operation.
6. Install a 9 volt rechargeable battery in the holder provided if you desire
the battery back up function AND you have the 120 Volt adapter. If you
do not have the 120 Volt adapter you may use any 9Volt battery, we
recommend Alkaline.
7. Check the system for proper operation and reassemble.
8. Using the peel-and-stick Velcro provided, mount the RDU where the
LED indicators can be easily seen.
IV Operation
When the unit is monitoring there are no LEDs lit, pressing RESET will
light the green LED to indicate OK.
• A flashing yellow light indicates that an alarm condition is being timed.
• A flashing red light means that an alarm condition has persisted for the
set time and has been transmitted to the monitoring device, this LED
will continue to flash even if the alarm condition has corrected itself.
• Pressing RESET will cause the red LED to stop flashing and reset the
output contacts to their normal non-alarm state, if the alarm condition
persists the yellow LED will again flash to indicate timing and, after
timing out, will light the red LED and change the output contacts.
NOTE It is important that the battery condition be checked regularly by pressing
RESET. A dead battery may prevent proper operation of the Alarm Delay
Module.
This is the hookup from a relay (contact) output of an LMS-188-4P, or other device,
to the RDU.
Use the slide switch on the main board to choose N.O. or N.C. input.
On the output side, the RDU offers Normally Open (4, 5) or Normally Closed (3, 4)
contacts, and may be connected to a dialer, beeper, strobe light, etc.

LMS Operating Manual Page 13
SOLENOID CONTROL OPTION
PROVIDED BY LEONARD VALVE
Description:
The Solenoid Control Option (SCO) is designed to accept dry contact inputs, either Normally Open
(N.O.) or Normally Closed (N.C.), in order to switch an AC powered solenoid opened or closed. Solenoid valve
and associated power supply are to be provided by others.
Application:
The primary application is in systems where it is desirable to control an AC powered solenoid in the event that
the alarm on the LMS-188-4P is active. When in non-alarm condition the relay is in a N.O. state and the
solenoid will allow water to flow through it freely. Once the alarm is active, the relay on the LMS-188-4P will
switch to N.C. and the solenoid will shut down. Solenoid valve and associated power supply are to be
provided by others.
Installation:
Included with every SCO is a 12 VDC/600 mA power source with a 10’ lead that requires a dedicated 110 VAC
outlet to plug into. See wiring diagram below for reference. Do Not Energize SCO, LMS-188-4P, or solenoid
valve until wiring is complete. Solenoid valve and associated power supply are to be provided by others.
1. Connections from the power source to the SCO (+ side to terminal 7), terminal to
solid state relay (terminals 3+ to 8), and power source to solid state relay (- side to terminal 4-) have
been made at the factory.
2. Properly ground the SCO by using the screw provided inside of the enclosure and
connect to suitable earth ground
3. Connect terminal 5(12VDC) to the COMMON ‘C’ terminal (9) of the LMS-188-4P
relay switch.
4. Connect either terminal 9 or 11 from the LMS-188-4P relay switch to terminal 6on
the terminal strip. Use terminal 9with N.C. solenoids; use terminal 11 with N.O. solenoids.
5. Connect the positive side of the solenoid power supply to terminal 1 on the solid state
relay.
6. Connect terminal 2on the sold state relay to the positive side of the solenoid valve.
Complete the circuit by connecting the neutral side of solenoid to the neutral side of power supply.

DC POWERED SOLENOID CONTROL
HARDWARE SUPPLIED BY OTHERS
Description:
This solution is for systems that utilize a DC powered solenoid valve and want to make use of the SPDT relay
switch included with LMS-188-4P. Solenoid valve and associated power supply are to be provided by
others.
Application:
The primary application is in systems where it is desirable to control a DC powered solenoid in the event that
the alarm on the LMS-188-4P is active. When in non-alarm condition the relay is in a N.O. state and the
solenoid will allow water to flow through it freely. Once the alarm is active, the relay on the LMS-188-4P will
switch to N.C. and the solenoid will shut down. Solenoid valve and associated power supply are to be
provided by others.
Installation:
Solenoid power supply is to be supplied by others and is not available from Leonard Valve. The relay contacts
are rated up to 30 V/1A. See wiring diagram below for reference. Do Not Energize LMS-188-4P or solenoid
valve until wiring is complete. Solenoid valve and associated power supply are to be provided by others.
1. Connect positive side of power supply to the COMMON terminal (2).
2. Connect either terminal 1 or 3 from LMS-188-4P relay switch to positive side of DC
solenoid. Use terminal 1with N.C. solenoids; use terminal 3with N.O. solenoids.
3. Connect neutral side of power supply directly to neutral side of DC solenoid.
