Switch Monitor Modules
Installation Instructions
General
This guide describes the installation of the following products:
Part Number Product Name
MRI-101P Priority Switch Monitor Module
MRI-100P Mini Priority Switch Monitor Module
Switch Monitor Modules are loop-powered devices that incorporate a monitored input circuit
for connection to remote switches. The MRI-101P modules are fascia plate mounted and
designed to t on a 4” square or 2 gang electrical box (minimum depth 2⅛”). Mini modules,
MRI-100P are housed in a small plastic enclosure for installation inside an electrical box. Six ying
leads are used to connect the module.
The priority switch monitors, MRI-101P and MRI-100P, incorporate an additional ‘Priority Interrupt’
to give a fast response from devices such as pull stations.
Note: the priority modules are designed for indoor use only.
Control Panel Compatibility
The modules have been listed by Underwriters Laboratories Inc. For details of compatible
panels, please contact Secutron. Please check re control panel literature for compatible
Secutron devices.
Installation
These products must be installed in accordance with the applicable NFPA standards, local
codes and jurisdictional authorities. Failure to follow these instructions may result in failure of
devices to report an alarm condition. Secutron is not responsible for devices which are improp-
erly installed, maintained and tested.
Before installing these products, check the continuity, polarity and insulation resistance of all
wiring. Check that siting is in accordance with the re system drawings and conforms to all
applicable local codes such as NFPA 72.
Installation: MRI-101P
1. Mount the electrical box as required and install all cables for termination. Ensure that
cable shield/earth continuity is maintained.
2. Drill holes in the fascia plate corresponding to the holes on the mounting box selected
(Fig 3).
3. Terminate all cables in compliance with local codes and regulations.
4. Set the address of the module as shown on page 3.
5. Gently push the completed assembly towards the mounting box and align the xing holes.
Secure the unit with the screws provided. Do not overtighten the screws.
6. Commission the module.
