The tri-zone wireless door/window contact (modelWS4965)adds value to any installation by providing installers with three zone and reliable 433 MHz technology. The device can be mounted in the traditional manner, or if that is inconvenient for applications such as garage doors, it can be configured for normally closed "tilt switch operation. In addition, the WS4965 has two normally closed external contact inputs that can be used for additional hardwired contacts or other dry contact switches. The internal contact provides a generous magnet gap of 1/2 (13 mm) and flexibility during difficult installations as it easily accommodates larger door or window frames.
