254-Point Analog/Addressable Life Safety System


Note:  The E-FSA250 has been replaced by the FX-1000 intelligent addressable panel.

The Edwards Signaling E-FSA250 life safety system offers the reliability of analog/addressable fire detection for small to mid-sized applications. Built to provide years of trouble-free service, this system benefits building owners and installers with rotory device addressing, optional Ethernet® connectivity, and a full line of easy-to-configure option cards and modules.

The E-FSA250 provides one Class A or Class B analog/addressable device loop that supports up to 127 devices. A second 127-point loop may be added to the E-FSA250 to expand total system capacity to up to 254 device addresses. The panel includes four NACs that may be wired for either Class A or Class
B operation.

The E-FSA250 supports a wide range of accessories and related equipment, including:

  • Intelligent modules and pull stations

  • Intelligent detectors, and bases

  • Remote annunciators

  • Option cards that expand system capacity and extend system capabilities.

    • Comes standard with one loop (expandable to two) that supports up to 127 (expandable to 254) analog/addressable devices

    • Supports intelligent modules, pull stations, detectors, and bases

    • Four Class B NACs or two Class A NACs

    • Form C contacts for alarm and trouble, Form A for supervisory

    • Rotary addressing on all intelligent addressable devices

    • Optional Ethernet port for diagnostics, programming and a variety of system reports

    • Two programmable switches with LEDs and custom labeling

    • Supports horn silence over two wires and UL 1971-compliant strobe synchronization

    • Standard Class A wiring

    • Supports up to eight serial annunciators (LCD, LED-only, and graphic interface)

    • Can use existing wiring for most retrofit applications

    • Upload/download remotely or locally

    • Two-level maintenance alert reporting

    • Pre-alarm and alarm verification by point

    • Adjustable detector sensitivity

    • 4 x 20 character backlit LCD display

    The E-FSA250 life safety system is a reliable analog/addressable solution for small to mid-sized buildings. Analog/Addressable Technology delivers the benefits of flexible system installation, while a clean and easy-to-operatate user interface makes panel operation and system maintenance quick and intuitive.

    Reliability you can count on
    The inherent fault-tolerant characteristics of Analog/Addressable Technology boosts the reliability of E-FSA250 systems. When combined with E-Series smoke and heat detectors, this system delivers a level of dependability not previously available for small to mid-sized applications. All E-Series systems are built to exacting Edwards reliability benchmarks and meet ISO 9001 standards for quality, in addition to agency listings for dependability.

    Flexibility built right in
    Two fully-programmable front panel switch/LED combinations provide an added measure of flexibility. Their slide-in labels take the mystery out of custom applications, and present a clean finished appearance.

    Perfect for retrofits
    The E-FSA250 is particularly well-suited to retrofit applications. All connections are made over standard wiring – no shielded cable required. This means that in most situations existing wiring can be used to upgrade a legacy control panel to E-FSA250 technology without the expense or disruption of rewiring the entire building.

    Signals with a difference
    E-FSA250 NACs are configurable to fully support Edwards notification appliances. These devices offer precision synchronization of strobes to UL 1971 standards. Enabling this feature allows connected horns to be silenced while strobes on the same two-wire circuit continue to flash until the panel is reset.

    Clear-cut remote annunciation
    Remote annunciation is a strong suit of the E-FSA250. Up to eight annunciators can be installed on a single system. Compatible annunciators include a range of LED and LCD models that provide zone or point annunciation, as well as common control capabilities.

    The E-FSA250 also supports graphic annunciation with optional Graphic Annunicator interface modules. Each interface provides common control, indicators, and 32 LEDS. Consult the Ordering Information section for details.

    A complete line of accessories
    The E-FSA250 life safety system is supported by a complete line of analog/addressable detectors, modules and related equipment. Consult the Ordering Information section for details.

    The front panel provides an easy-to-use operator’s interface, as well as all the necessary controls for front panel programming. A large back-lit 80-character LCD displays system status, event details, and programming prompts. Large tactile control buttons are easy to see in low light conditions, and bright multi-color LEDs offer at-a-glance status indication.
