Do you have a question about the Mircom FA-1025T and is the answer not in the manual?

Overview

The FA-1025T is a sophisticated Fire Alarm Control Panel designed to provide comprehensive fire detection and alarm capabilities for various applications. This ULC-listed panel is engineered to meet all performance and operational requirements set forth by Underwriter's Laboratories of Canada (ULC), ensuring reliability and compliance with safety standards.

Function Description

At its core, the FA-1025T is a supervised five-zone, 24VDC Fire Alarm Control Panel. This means it can monitor up to five distinct areas for fire conditions, providing a robust and segmented approach to fire safety. Each of these detection zones operates as a Class B circuit, a common wiring configuration that allows for easy installation and maintenance.

Beyond detection, the panel features two Class B signal zones, capable of delivering up to 1.7A of signal power. These zones are crucial for activating audible and visual notification appliances like bells and horns, alerting occupants to a fire event. The panel offers flexibility in how these signals are activated, with DIP switch selectable outputs for either Temporal Code 3 (a standardized fire alarm sound pattern) or Steady signals, allowing customization based on local codes or preferences.

The FA-1025T integrates essential relay contacts for both alarm and trouble conditions. These relays provide outputs that can be used to interface with other building systems, such as HVAC shutdown, elevator recall, or remote monitoring stations, enhancing the overall safety infrastructure.

Remote annunciation is a key feature, allowing for the extension of alarm and trouble indications to remote locations. This includes remote trouble indicators and buzzers, as well as supervised alarm annunciation, which ensures that the remote indicators themselves are functioning correctly. This capability is vital for large facilities or those with multiple points of entry/exit where centralized monitoring might not be immediately visible.

Powering the system, the panel is designed to operate on A.C. power with battery backup. It supports 24V 4AH Gel Cell or Sealed Lead-Acid batteries for standby power, with options for 24 hours of standby and 5 or 30 minutes of alarm, depending on the specific battery configuration and load. The panel's electrical rating is 120V, 60Hz, 1A or 240V, 50Hz, 0.5A, making it adaptable to different electrical environments.

Usage Features

The FA-1025T offers a user-friendly interface with a range of LED indicators and control switches, providing clear status information and operational flexibility.

For immediate status updates, the panel includes LED indicators for various conditions:

  • A.C. On: A green LED confirms that the panel is receiving A.C. power.
  • Zone Alarm and Trouble: Red LEDs indicate an alarm condition in a specific zone, while yellow LEDs signify a trouble condition in that zone.
  • Battery Fault: A yellow LED illuminates to indicate issues with the battery, such as removal, low voltage, or open battery leads.
  • Ground Fault: A yellow LED signals a ground fault of 10K ohms or less within the system wiring.
  • Common Trouble: A yellow LED flashes (or illuminates steadily if DSW1-8 is ON) for any trouble condition detected by the panel, accompanied by an intermittent buzzer.
  • Signal Trouble: A yellow LED (located behind the display plate) indicates an open or short circuit in the signal zone wiring.
  • Signal Silenced: A yellow LED confirms that the alarm signals have been silenced.
  • Remote Lamp Fail: A yellow LED illuminates for an open circuit in the supervised remote annunciator wiring.

Control switches provide essential operational capabilities:

  • Buzzer/Buzzer Silence Switch: This switch allows users to silence the intermittent trouble buzzer. In an alarm condition, the buzzer sounds steadily, and operating this switch will silence it. Any subsequent alarm will reactivate the buzzer.
  • Individual Zone Silence/Disconnect Switch: Each zone has a dedicated switch, offering granular control over specific detection areas.
  • Reset/Lamp Test Switch: Operating the reset switch restores all latched functions and resets smoke detectors after the products of combustion have cleared. Holding the switch for five seconds initiates a lamp test, illuminating all LEDs to confirm their functionality, in addition to resetting the panel.

The panel's behavior can be customized through DIP switch DSW1 and several jumpers:

  • DSW1: This DIP switch configures signal zone outputs (Temporal Code or Steady), signal silence inhibit (e.g., a 60-second inhibit period before signals can be silenced), and the common trouble flash rate.
  • Jumpers (JW1-JW7): These jumpers allow for advanced function selection, such as making the +24V DC supply resettable (JW1), making the auxiliary relay disconnectable (JW2), selecting normally open or normally closed trouble contacts (JW3, JW4), configuring non-latching alarm zones (JW5, JW6), and enabling supervision of remote annunciation alarm zone indicators (JW7).

The sequence of operation is straightforward:

  • Normal: All indicators are OFF, except for the green A.C. On LED.
  • Alarm: A red zone alarm LED illuminates steadily, and signals activate according to the DSW1 settings.
  • Signal Silence: After any inhibit period, the buzzer can be silenced, and the Signal Silenced LED illuminates.
  • Reset/Lamp Test: Resets the system and allows for verification of LED functionality.

Maintenance Features

The FA-1025T is designed with maintenance and troubleshooting in mind, offering features that simplify system checks and fault identification.

Before initial power-up, a system checkout procedure is recommended:

  1. Wiring Verification: Thoroughly check all external wiring for opens, shorts, or ground faults.
  2. Transformer Connections: Ensure transformer cables are securely connected.
  3. A.C. Power Wiring: Verify proper A.C. power wiring, but do not connect batteries yet to prevent sparking.
  4. Switch Positions: Confirm all switches are in their normal (left) position.

After power-up, the panel provides clear indications for troubleshooting:

  • Initial Power-up: The A.C. On LED should illuminate. The trouble buzzer will sound intermittently, and the Common Trouble LED will flash, indicating a battery fault (as batteries are not yet connected).
  • Battery Connection: Once batteries are carefully connected with correct polarity, the Common Trouble LED should extinguish. If it remains on, the front panel LEDs will guide the technician to the specific fault:
    • Battery LED: Indicates low battery voltage (below 20.4V).
    • Ground Fault LED: Pinpoints a ground fault on extended wires.
    • Zone Trouble LED: Signals an open loop in zone wiring or an incorrectly positioned signal silence switch.
    • Signal Trouble LED: Identifies an open loop or short in the signal zone.

The manual provides detailed wiring tables for detection zones, bells, and horns, including wire gauge recommendations and maximum wiring run distances, which are crucial for proper installation and system performance. These tables help technicians ensure that wiring adheres to electrical codes and maintains signal integrity.

Furthermore, the manual includes comprehensive compatibility lists for 2-wire smoke detectors from various manufacturers (Mircom, Cerebrus Pyrotronics, Fenwal, System Sensor, Mirtone, Edwards, Simplex, Sentrol - ESL, Detection Systems Inc.) and signaling devices (System Sensor - SpectrAlert, Wheelock, Gentex, Mircom). This information is essential for selecting compatible devices, ensuring the system operates as intended and meets regulatory requirements. Notes on total standby current for detectors and reset times are also provided to aid in system design and maintenance.

A dedicated section on battery calculations (Appendix B) serves as a selection guide, allowing installers to determine the required battery capacity based on standby and alarm current draw. This ensures that the system has sufficient power backup for the specified duration, a critical aspect of fire alarm system reliability. The guide also notes that larger batteries may require an external battery box, aiding in planning the physical installation.

The FA-1025T's design, with its clear indicators, customizable functions, and detailed documentation, aims to provide a reliable fire alarm control panel that is both effective in operation and manageable in terms of installation and ongoing maintenance.
