Skylink WD-434RTL Door/Window Alert Kit Alarm System

SKU WD-434RTL Category


When you need a simple system that will alert you when a closed door or window is opened, the WD-434RTL by Skylink is a great choice.  The door/window contact will send a wireless signal up to 800 feet to the recevier, playing a beep or alarm sound, as well as a flashing LED that corresponds to the preset zone.

A simple alarm-type of system doesn’t mean it’s not effective.  Many people want notifications or alerts when doors or windows are opened, but don’t want an elaborate system, especially a system where you might have to pay for monitoring.

The WD-434RTL is a kit that features a door/window contact (battery powered) and one plug-in receiver.  When a monitored door (or window) is opened, the sensor/transmitter will send a wireless signal up to 800 ft. to the receiver (HA-434RL) that’s included in this kit.
