ELK   WSV - Water Shutoff Valve ELK ELK-MA100 iButton Touchkey Reader & Interface Pack
The ELK-WSV is a Professional Grade, electrically operated water shutoff valve for both residential and commercial use. Used in conjunction with an automation controller, leak detection devices, or a simple manual pushbutton, the WSV can easily and conveniently shut off the main water supply to the building. Unlike competitors. units, the ELK-WSV is a stainless steel, 1. full bore, ball valve with commercial grade seats and seals. It is a non-restricting valve which meets the approvals of state and municipal water authorities. The motorized actuator has a permanently lubricated gear drive with sufficient torque to open or close the valve under high pressure or after long periods of inactivity. The ELK-WSV valve can be operated via a simple 12 Volt DC input from a security or automation controller such as the ELK-M1 Gold or M1EZ8. It can also be attached directly to a 12Vdc power source through a SPDT Emergency Pushbutton or "Easy" button for manual control. Operating time from fully open to fully closed is less than 4 seconds.

  • The ELK-930 performs three functions. It can detect ring activation from one or two doorbell buttons and a single telephone line. It conveniently isolates the voltage and current and produces an open collector (pull to ground) output which can be used to trigger an automation controller, relay, timer, etc. The circuit is pre-scored so that the individual detectors may be snapped off (separated) from each other. The ELK-930 Doorbell Detector monitors the current draw of a doorbell and produces an open collector output when the pushbutton is pressed and the doorbell draws 900mA or more. This open collector output can be used to trigger an automation controller input that utilizes high to low switching (pull to ground) for activation. The ELK-930 Telephone Ring Detector monitors the voltage on the telephone line and produces an open collector output (pull to ground) when the telephone ringing voltage is approximately 50 Volts or greater. The output follows the ringing pattern.


    Max Input on Doorbell Boards: 24 Volts AC Nominal
    Max Output: 40mA @ 12 Volts D.C.
    Doorbell Detection Current: 900mA min.
    Size: 3.4" x 2.75" x .625"
