  • SECO-LARM ENFORCER 190/190S — Glass Break Detector Installation Instructions

    September 08, 2026 2 min read

    Installation instructions and specifications for the SECO-LARM ENFORCER 190/190S audio-discriminator glass break detector.

    Full text manual (for reference)

    Overview

    The SECO-LARM ENFORCER 190/190S is an audio-discriminator glass break detector for perimeter security, designed to detect the high-frequency sound of glass breaking. Its patented yellow "turbulence" LED allows fast, easy sensitivity adjustment without needing an external test meter — eliminating a common source of false alarms with older glass break detectors.

    Key Features

    • Patented yellow turbulence LED for fast, pinpoint sensitivity adjustment without external test equipment
    • Detects the high-frequency sound of glass breaking
    • ENFORCER 190: wide 25' radius protection if ceiling-mounted, 45' if wall-mounted
    • ENFORCER 190S: wide 20' radius protection if ceiling-mounted, 35' if wall-mounted
    • Red trigger LED indicates when a trigger signal is sent to the alarm
    • Tamper-proof case
    • Installs without RF-shielded cable
    • Compact, unobtrusive design suitable for any room

    How It Works

    A single ENFORCER 190/190S, ceiling-mounted, can protect all windows and doors within a 15' radius — eliminating the need for individual detectors on each pane of glass. The relay output is programmed for a 2-second reset.

    Installation Hints

    • The ENFORCER 190/190S usually receives power from the alarm panel. If connected to a separate power source, it should also be connected to a rechargeable battery in case AC power fails.
    • Use either Terminals 2 and 3 for N.O. output, or Terminals 2 and 1 for N.C. output — but not both.
    • Close all doors and windows when the ENFORCER 190/190S is in use.
    • Mount any memory buzzer, musical device, or other sound-generating equipment as far from the ENFORCER 190/190S as possible to reduce the chance of accidental triggering and to reduce the chance of a thief locating the detector.
