Secutron Addressable Mini Dual Input Module MRI-4041, Single Gang
Two circuits. One address.
A single-gang addressable module that monitors two independent Class B circuits on one address, or sets itself to Class A, based on what the fire alarm panel sends.

Every monitored circuit shouldn't need its own address.
Addressable loops fill up fast when each input uses a module address. This module monitors two independent circuits in Class B using one address.
Built for addressable fire loops
Configuration comes from the fire alarm panel, so the module adapts to the circuit style your system calls for.
Automatic Class A or B
Inputs are set to single Class A or dual Class B according to the configuration sent by the fire alarm panel.

Devices per SLC
Any combination of MRI-4000 series devices up to 240 can be connected on a single SLC.
No EOL in Class A
No EOL resistor is required when the input is in Class A operation.
Single gang fit
Fits in a single gang junction box.
LED status indication
An indicating LED provides module status, alongside fast, reliable contact monitoring.
