Batteryless/Wireless Security Solution Introduced by EnOcean & Ad Hoc Electronics



Boston MA and Lindon UT (USA) - May 18th 2006 - EnOcean, Inc., global pioneer in energy-harvesting wireless technologies, has partnered with Ad Hoc Electronics to enable its award-winning self-powered magnetic proximity sensor for retro-fit security installations. The combination of Ad Hoc's new LVRX-4 low-voltage relay receiver and the STM250 system enables home and building owners to enhance their existing entry/exit security equipment using reliable wireless, battery-free sensors.

This unique collaboration of self-powered window/door contact switch with relay receiver box lets users add security coverage to additional rooms, remodels, unattached buildings, even cabinets or movable assets within those buildings. Installation is simple: the LVRX-4 receiver is plugged into an open input on the security control panel, while the self-powered STM250 magnetic proximity sensor and transmitter are integrated into the monitoring point. The magnetic contacts attach via tape or screws, just like conventional contacts.

"Last fall, EnOcean took the security market by storm, with our pioneering introduction of magnetic contact technology that required absolutely no wires and no batteries," said Jim O'Callaghan, Vice President of EnOcean. "However, the product was designed specifically for integration with new products. Now, LVRX-4 makes STM250 suitable for use with existing products and systems. The LVRX-4 allows the STM250 wireless security sensors to be used to extend nearly any new or existing security installation."

"Ad Hoc brings years of RF experience and a thorough understanding of security and home automation to the STM250 product equation," added Jan Finlinson, Vice President of Ad Hoc Electronics. "By combining our LVRX-4 with the maintenance-free STM250 system, EnOcean promises its customers in the security industry dependable operation for decades to come."

STM250 Overview
Packed into a small 110 x 19 x 15 mm device - similar to a standard doorbell - STM250 is a solar-powered, magnet-contact sensor combined with an embedded RF transmitter. The device requires only ambient indoor light to power itself continuously, as well as to store backup energy for up to six days use in total darkness. It gathers energy via its tiny solar cell, which generates enough output power to communicate throughout an entire house.

The unit's wireless transmitter will send a signal up to 300 meters outdoors or 30 meters indoors. To ensure dependable communication, STM250's suite of sophisticated RF protocols includes multiple broadcasts, fast data rates, error detection and unique addressing. Signals are transmitted immediately when the contact is opened or closed. A periodic presence signal is sent to indicate that the node is operating properly.

LVRX-4 Overview
LVRX-4 is a four-channel low voltage relay receiver device used to connect wireless switches and sensors to existing security systems. The 130 x 70 x 29 mm unit communicates via the 868MHz RF band and attaches to the sensor input terminals of existing security control panels. Status LEDs reassure the user that security signals are constantly being received.

LVRX-4's relay output channels continuously mirror the status of STM250. The relays can be linked either to magnetic proximity door or window sensors, or to wall-mounted or handheld push switches. LVRX-4 connects to STM250 with a simply ID-learn-sequence that stores transmitter Ids in EEPROM, so that the LVRX-4 knows which devices are connected to which relay output. Each output can be controlled by up to 15 transmitters.

STM250/LVRX-4 will serve either as ready-to-install equipment for security system contractors, or as an OEM-level product for integration into doors and windows at the factory. Thanks to its intrinsic stability, it can even be permanently embedded inside impossible-to-reach places, such as between panes of window glass. The complete system is available directly from Ad Hoc Electronics. All proprietary radio technology featured is approved for use in Europe (ETSI), US (FCC) and Canada (IC).
