The ELK-6021 is an exceptionally thin Wireless Window Sensor. It is designed primarily for use on non-metal surfaces and is ideal for double-hung or casement-style wood/vinyl windows. It is nearly invisible when installed properly.

The 6021 is compatible with Wireless Transceivers and Controls that accept Elk’s two-way technology such as the ELK-M1XRFTWM. The 6021 contains a built-in reed switch and reports a unique TXID identifier to the transceiver.

The 6021 features Elk’s Industry Leading Two-Way Technology with positive signal acknowledgment and very good battery life.
