INTRODUCTION
RM2 SYSTEM
The RM2-ARD is a 2-channel, 4-20 mA input
of Net Safety’s monitoring devices. Channel #1
independently and can be used for any combination of
detectors, toxic gas se nsors or combustible sensor with transmitters. The
available outputs from this device are: 4-20 mA analog signal, relay and
digital for Modbus applications. For Modbus setup see pages 17-20.
Note: All three (3) outputs can be utilized at the same time.

and Channel #2 function
Net Safety’s fire
Fire Head
Net Safety’s UV/IRS, UVS, IRS, UVU-120-H2 and Phoenix IR3S fire detector
heads can be used in conjunction with the RM2.
ST Series Sensors
A variety of Net Safety’s ST Series 4-20 mA Toxic gas sensors can be
connected to the RM2.
Combustible Sensors and Transmitters / Controllers
Net Safety’s Uni-Tran and Millennium Combustible Gas Controllers or
Transmitters can be used in conjunction with the RM2. Combustible sensors
should always be connected to transmitter or controller . The 4-20 output from
this combination then connected to the RM2.
Manual
The manual has been designed to make installation of the RM2 System easy. To
ensure proper installation and usage follow the simple steps outlined in the
following pages. Consult the manual provided with the detector device(s) being
connected to the RM2 for specific information.
If you encounter any problems, consult the troubleshooting section or contact
your sales representative.

STEP 1 — INSTALL
UNPACK
Carefully remove all components from the packaging. Check components
against the enclosed packing list and inspect all components for obvious
damage such as broken or loose parts. If you find any components missing or
damaged, notify your representative or Net Safety Monitoring immediately.
Locate
Locate Fire Heads, Sensors, Controllers or Transmitters as per the manual
provided with the specific product.

STEP 2 — WIRE
FIELD INSTALLATION
WARNING: Wiring codes and regulations may vary. Wiring must comply
with applicable regulations relating to the installation of electrical equipment
and is the responsibility of the installer. If in doubt, consult a qualified official
before wiring the system.
The following figures illustrate the basic connections for a Fire Head, Sensor,
Controller or Transmitter as well as information for external equipment.
Consult the manual for the specific Fire Head, Controller or Transmitter
regarding further wiring information.
Configuration
Two Analog Input channels with Current Loop and Relay and Digital Output.
Refer to Figure 2, "Analog/Relay/Digital RM2 System Board—Wiring",
on page 3 for illustration.
SETTINGS
Once field wiring is complete, the Relay Contacts and the Isolated/Non-isolated
analog outputs should be configured.
Using Jumpers
Place Jumper(s) over appropriate pins in order to set
Relays Contacts as Open or Closed, and set Isolated or
Non-isolated analog output. See Figure 2 on page 3.
Relay Outputs
The relay outputs have SPDT, form C, normally open/normally closed contacts
rated for 5 Amps @ 30 V dc or 250 V ac. Each channel has two dedicated alarm
relays and a fifth relay is a Common Fault relay.

Mount
The RM2 can be fitted into a cage and located in a Class 1, Division 2 location.
RM2-ARD 2
Current Outputs
A 4-20 mA dc analog current output (isolated/non-isolated) transmits
information to other devices.
Digital Outputs
For digital output, connections to PLC (RTU) are made via terminals
19 and 20 (A and B)for Modbus communications. See page 3 and pages 17-20.
RS 485 Bus Terminator Jumpers (JP9 and JP11) should be placed over jumper pins
for Modbus communication. The user should wire the system according to RS 485
convention and local Electrical codes.

STEP 3 — OPERATE
START UP
Once all terminal wiring and Jumper settings are complete, the RM2 may be
powered up.
The time it takes the RM2 to power up is dependent on whether it is connected
to a Fire head , a transmitter/controller with sensor or directly to ST series sensor.
