2.0 Introduction
Secutron’s MR-2300 LED Series Fire Alarm Control Panel is a Digital Signal Processor (DSP)-
based fire panel. The MR-2300 provides a maximum of 12 supervised Class B or A Initiating
circuits, and maximum four supervised Class B or A indicating circuits. All circuits are
supervised for opens and ground faults, and indicating circuits are supervised for shorts.
Optional modules include Relay, Polarity Reversal and City Tie and Class A Converters for
initiating and indicating circuits. Semi-flush or surface mountable enclosures can be used for
retrofits and on new installations.
2.1 Overall Features
• Basic unit has 12 Class B initiating circuits, which may be configured as Class A using
input Class A converter adder modules. Each initiating circuit can be configured as
Alarm, Verified Alarm, Water flow Alarm, Sprinkler Alarm, Latching or Non-Latching
Supervisory, Property and Building Safety, or Trouble-Only circuits. There are two LEDs
per circuit, one for Trouble (amber), and one dual color (amber/red) LED for Supervisory
(amber) and Alarm (red).
• Basic unit has four Power Limited Class B indicating circuits with individual trouble
indicators. Each indicating circuit may be configured as Class A using output Class A
converter adder module. Each indicating circuit may be configured as Silenceable
signal, non Silenceable signal, Silenceable strobe, non Silenceable strobe. The audible
signal may be Steady, Temporal Code, California Code, or March Time.
• Two Stage operation available.
• A pushbutton associated with each initiating and indicating circuit can individually
disconnect the circuit.
• Configurable Signal Silence Inhibit, Auto Signal Silence, Two-Stage Operation, and
One-Man Walk Test.
• Subsequent Alarm, Supervisory, and Trouble operation.
• Four-wire resettable smoke power supply 300 mA maximum class B with EOL relay.
• Relay Contacts for Common Alarm, Common Supervisory and Common Trouble all
non-disconnectable and Auxiliary Alarm Relay (disconnectable).
• RS-485 Interface for LCD Annunciators, RA-1000 Series Remote Multiplex
Annunciators and Smart relay adder.
• Optional Modules for additional Relay Circuits, City Tie and Polarity Reversal Signaling.
• Extensive transient protection.
• With or without built-in UDACT (Digital Alarm Communicator Transmitter).
• Easy configuration of the panel and built-in UDACT using LCD service tool (CFG-300).
• Remote dial up (with built-in UDACT version) for event log checking and/or configuration
changing.
• Laptop programmer for direct configuration changing and log checking.
Note: Installation of the MR-2300 LED Series fire alarm control panel should be in
accordance with Canadian Electrical Code Part 1, ULC-S524 installation of Fire
Alarm System, National Electrical Code NFPA 70 and NFPA 72. Final
acceptance subject to the Local Authority Having Jurisdiction (AHJ).
