    Installation and programming instructions for the ELK-319GB Wireless Glass Break Detector.

    Full text manual (for reference)

    Installation and programming instructions for the ELK-319GB Wireless Glass Break Detector — a supervised, battery-powered glass break sensor compatible with Elk's 319MHz receivers/panels and other 319.5MHz panels using the ITI/Interlogix protocol.

    Description

    The ELK-319GB is a supervised wireless glass break detector providing alarm, tamper, and low battery signal transmissions. Powered by two (2) replaceable 3VDC lithium batteries, it's compatible with Elk's 319MHz Receivers/Panels as well as many other panels operating on the 319.5MHz frequency that adhere to the ITI/Interlogix protocol.

    Specifications

    RF Frequency 319.5MHz
    Battery Type Two (2) 3VDC lithium batteries (Panasonic CR123 or equiv.)
    Tamper Switch Front cover and pry-off detect
    Range 20 ft (6m) max, 4 sensitivity settings
    Operating Temp -14 to 122°F (-10 to 50°C)
    Max. Humidity 90% RH, non-condensing
    Dimensions 3.9" x 2.75" x 1.5"

    Programming (Enrollment)

    General guideline for enrolling the sensor — for more extensive instructions refer to your receiver or panel manual.

    1. Place the panel into Program mode.
    2. Proceed to the WIRELESS SETUP menu.
    3. Select the appropriate zone/sensor location number.
    4. When the panel prompts to trip the sensor: separate the sensor from the mounting base, and remove battery pull tabs (if present) to power the sensor. The panel should acknowledge the sensor has been learned via a keypad display and/or audio alert. If enrollment doesn't succeed, repeat by removing/reinstalling the battery or pressing/releasing the tamper plunger.
    5. For additional sensors, repeat the process, then proceed to zone programming to assign each sensor's zone definition. Important: set the Zone Loop as "1".
    6. Exit the panel's Program mode when finished.

    LED Operation & Testing

    In normal operation, the red LED lights solid for 5 seconds whenever glass breakage is detected. When batteries are first installed, a 5-minute test mode is active, during which you can test microphone detection range by clapping or jingling keys. Test mode can be restarted for another 5 minutes by removing and reinstalling the batteries.

    Red LED Condition
    Slow flash (once per second) Test mode is active
    Rapid flash for approx. 2 seconds Sound detected
    ON solid for 5 seconds Alarm (normal operation)

    Sensitivity and Range Settings

    DIP switches select sensitivity, which also affects detection range. Default setting is MAX.

    Sensitivity Detect Range SW1-1 SW1-2
    MAX 6M OFF OFF
    MEDIUM 4M OFF ON
    LOW 2.5M ON OFF
    LOWEST 1.5M ON ON

    Installation Guidelines

    • Mount the unit at a height no lower than 6½ ft.
    • Maintain a distance of at least 4 ft. from any active ultrasonic sensors or devices.
    • All monitored glass must be within a clear line of sight of the unit; distance to the most remote point of monitored glass must not exceed 20 ft (6m).
    • Do not mount outdoors.
    • Install within 100 ft. of the receiver or panel.
    • Do not mount on metal surfaces — reduces range.
    • Mounting surface must be solid with no vibration.

    Recommended mounting configurations include ceiling mounting for windows on adjacent walls, wall mounting for windows on the same wall, and wall mounting for windows on an opposite wall — avoid mounting between a window and curtains/louvers or in other obstructed locations.

    Battery Life and Replacement

    Battery life depends on environmental temperature and how often the sensor transmits signals. The sensor sends a low-battery indication to the panel when it detects low battery voltage — replace both batteries as soon as possible.

    • Depress the cover latch on the top edge and lower the cover.
    • Remove both batteries and install two (2) new batteries, observing (+) polarity marked on the batteries and circuit board.

    Caution: Battery may explode if mistreated. Do not recharge, disassemble, incinerate, or expose to heat above 212°F (100°C). Keep away from children. Dispose of used lithium batteries according to local hazardous waste disposal laws.
