2.0 Introduction
Secutron's MR-2300 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 (Style B or
D) Initiating circuits, and maximum of four supervised Class B or A (Style Y or Z) 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 six Class B (Style B) initiating circuits, which may be configured as Class
A (Style D) using input Class A converter adder module. Each initiating circuit can be
configured as Alarm, Verified Alarm, Water flow Alarm, Sprinkler Alarm, Latching or
Non-Latching Supervisory, Monitor or Trouble-Only circuits.
• Basic unit has two Power Limited Class B (Style Y) indicating circuits. Each indicating
circuit may be configured as Class A (Style Z) 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.
• Each initiating and indicating circuit can be individually disconnected via the keypad and
LCD display with Password Access.
• Configurable Signal Silence Inhibit, Auto Signal Silence, and One-Man Walk Test.
• Four-wire resettable smoke power supply 300mA maximum.
• Relay Contacts for Common Alarm, Common Supervisory and Common Trouble all
non-disconnect-able and Auxiliary Alarm Relay (disconnectable).
• RS-485 Interface for MR-2300 Series Remote Multiplex Annunciators, LCD
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 using front LCD display and keypad.
• 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 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).
