Quick Start Guide
The MRLDS-450 refrigerant gas detector is
designed for use in refrigeration applications and
may be used as a stand-alone device, or connected
to a facility’s building management system (BMS).
It enables compliance with refrigerant safety codes
(ASHRAE 15 and EN378) and features audible and
visual alarms to alert personnel in the event of a
refrigerant leak.
DANGER: The MRLDS-450 is NOT certified or approved for operation in oxygen-enriched
atmospheres. Failure to comply may result in severe injury or death.
WARNING: Use this product ONLY for the purposes and under the conditions listed in the user
manual. Failure to comply may result in injury and/or damage to the product. The MRLDS-450
has not been designed to be intrinsically safe for use in areas classified as being hazardous
locations. For your safety, DO NOT use in hazardous locations. Consult a qualified professional
before connecting the MRLDS-450 to devices not mentioned in this manual. Failure to comply
may result in injury and/or damage to the product.
The gas diffusion path can become occluded (moisture, dust, debris, frozen condensation)
over time, resulting in reduced or complete lack of gas detection and alarming function.
Routine visual inspection of the gas detector and bump testing are recommended to ensure
proper gas detection and alarm function. For information on calibrating the sensor, refer to the
Care and Maintenance section of the MRLDS-450 User Manual P/N 026-1316.
CAUTION: Except for the maintenance detailed in this manual, this product should ONLY be
opened and/or serviced by authorized personnel. Failure to comply may void the warranty.
CODE COMPLIANCE: Comply with all local and national laws, rules and regulations associated
with this equipment. Operators should be aware of the regulations and standards in their
industry/locality for the operation of the MRLDS-450.
TECHNICIAN USE ONLY: The MRLDS-450 must be installed by a suitably qualified technician
who will install this unit in accordance with these instructions and the standards in their
particular industry/locality. This document is only intended as a guide and the manufacturer
bears no responsibility for the installation or operation of this unit. Failure to install and operate
the unit in accordance with these instructions and with industry guidelines may cause serious
injury or death and the manufacturer will not be held responsible in this regard.

4 Installation
The manufacturer of this product requires that a bump test or calibration be performed
following installation to verify installation to verify instrument functionality.
DO NOT allow the lid/sensor to hang from the ribbon cable. Failure to comply may result in
damage to the product.
1. Mount the MRLDS-450 according to the product dimensions, maximum wiring lengths,
and following considerations:
• Environment: the full range of environmental conditions when selecting a
location.
• Application: the specifics of the application (possible leaks,
air movement/draft, etc.) when selecting a location.
• Accessibility: the degree of accessibility required for maintenance purposes
when selecting a location.
• Target Gas: the specific gravity of the target gas when selecting the height of the
instrument.
2. Using a 5/32” (4mm) hex key/allen wrench (not included), remove the lid and
disconnect the ribbon cable from the base.
3. Set the lid and rubber gasket aside to be reinstalled later.
STEP 1: Mount Gas Detector & Remove Lid
STEP 2: Wire Connections
Ensure that all wiring connections are made BEFORE applying power.
Relays are rated for 0 to 30V. DO NOT apply main power onto these relays.
Cable glands are meant to accommodate one cable. DO NOT use cable glands for more than
one cable.
If analog output is 4 to 20 mA, connect or short the connection to ensure the gas detector does
not go into fault.

1. Locate connections (Power, Analog, Modbus, Relays) and remove terminal blocks from the PCBA.
Power Modbus Analog Relay x3
2. Remove plugs from the corresponding M16 cable glands and pass the cable through the opening.
3. Secure wires in each terminal block and, pressing firmly, reinstall the terminal block in the PCBA.
4. Remove all excess cable from the housing before firmly securing the cable glands.
STEP 3: Reinstall Sensor and Connect Lid
DO NOT leave excess cable inside of the gas detector housing. Failure to comply may result in
damage to the product.
To achieve proper seal in the IP66 enclosure, the lid screws should be torqued to 15 to 20 lbf in
(1.5 to 2.0 Nm).
1. Reinstall the rubber gasket. Ensure that it is
correctly seated by placing the side with two
grooves face down and the edge with two
bumps on the top.
2. Reconnect the ribbon cable from the sensor
to the PCBA as shown:
3. Ensure no cables are interfering with the
sensor module and close the lid.
4. Using a 5/32” (4 mm) hex key/allen wrench,
tighten the lid screws in an X tightening

Quick Start Guide
5 MRLDS-450 Network Setup for Site Supervisor and E2
For Modbus end-of-line termination, use 150Ωohm resistor or termination block P/N 537-2711. Do not use
MRLDS 120Ωohm on-board termination with Site Supervisor or E2.
• For 24 VAC installations sharing a transformer in a daisy-chain configuration, the neutral
polarity must be maintained for all instruments.
• 24 VAC power polarity must not be reversed.
• For a more robust system, a dedicated transformer for each MRLDS is recommended to
prevent damage caused by wiring errors.
• Fasten terminal screws.

6 Connect MRLDS-450 to MRLDS-400 Series App
(User Discretion)
The MRLDS-450 uses a smartphone application to allow users to interface with the gas detector.
Default alias, passkey, and unlock code can be changed via the MRLDS-400 Series App’s
configuration menu.
1. Enable Bluetooth® discovery by tapping MAG#1 for 1 second. (After 10 seconds, the device will
indicate that it is discoverable with audible heartbeat until it has been paired, discovery has timed-out
or has been canceled.)
2. Launch the MRLDS-400 App and click the Bluetooth® icon at the bottom of the screen to initiate a
scan.
3. Select the instrument (default is 18TMAE) from the list of available gas detectors.
4. When prompted, enter the passkey (default is 123456).
5. Go to Configure tab to set up the device. When prompted, enter unlock code to access device
configuration (default is 1234).
