INSTALLATION INSTRUCTIONS FOR M901R, M901R-KO
AND M901RDIN MAINS SWITCHING OUTPUT MODULES
This manual is intended as a quick reference installation guide. Please refer to the control panel manufacturers installation manual for detailed
system information
GENERAL INFORMATION
The M900 series of modules are a family of microprocessor controlled interface devices permitting the monitoring and/or control of auxiliary
devices. The M901R, M901R-KO and M901RDIN are output modules, providing 250VAC 5A rated voltage free contacts, both normally open and
normally closed.

Maximum Wire Gauge 1.5mm²
INSTALLATION
Note: These modules must only be connected to control panels using compatible proprietary analogue addressable communication protocols
for monitoring and control.
Disconnect loop power before installing modules or sensors.
High voltages may be present on terminals 7 to 12.
M901R and M901R-KO
1. The M901R ( -KO ) includes a custom low profile surface-mounting box with several options for fixing centres. To access all fixing points,
and the rear cable entry knock out, the circuit board must be removed. It is held in place by two screws through the circuit board. Ensure
that these screws are replaced when refitting the circuit board.
2. If rear cable entry is not required, the box has several cover drill points permitting the entry of cables using suitable glands.
3. Wiring to the M901R ( -KO ) is made via two 6 way terminal strips on the module circuit board, capable of supporting conductors up to
2.5mm². See figure 2 for connections.
4. An earthing terminal is provided in the surface mount box for connection of the loop cable screen, if used, to ensure continuity. See figure 1a.
M901RDIN
1. M901RDIN mounts onto standard 35mm x 7.5mm "Top Hat" DIN rail. It must be mounted in a suitable cabinet meeting the applicable safety
standards.
2. Wiring to the M901RDIN is via plug in type terminals capable of supporting conductors up to 2.5mm². See figure 2 for connections.
Ensure that the correct terminals are used for the loop and switched voltage as damage may result from incorrect usage.
For both modules, the address is selected by means of rotary decade address switches (see figure 2), accessed at the front of the module. A
screwdriver should be used to rotate the wheels to select the desired address.
Short Circuit Isolators
All M900 series modules are provided with short circuit monitoring and isolators on the intelligent loop. If required the isolators may be wired out
of the loop to facilitate the use of the modules on high current loaded loops, for example if sounders are used. To achieve this, the loop out positive
should be wired to terminal 5 rather than terminal 2.

Notes:
1. If short circuit isolation is not required, then the loop output should be wired to terminal 5 rather than terminal 2. Terminal 5 is internally
connected directly to terminal 4.
2. In order to meet the requirements of European Safety Standards, ensure that all cables carrying voltages in excess of 48V (Live and
Neutral) are suitably fused.
