Inovonics EN1210W Door/Window Transmitter with Reed Switch

The Inovonics EN1210W is a wireless door and window transmitter with a built-in magnetic reed switch and external contact input for commercial security systems. Operating on the 902-928 MHz EchoStream frequency range, it supports a 5/8-inch (16 mm) magnetic contact gap, normally open or normally closed wired contacts, and integrated case tamper protection. The fully supervised transmitter sends check-in messages every 3 minutes and operates on a replaceable CR123A lithium battery with a typical 3-5-year service life.

Inovonics EN1210W EchoStream Wireless Door/Window Transmitter with Reed Switch

The Inovonics EN1210W Door/Window Transmitter with Reed Switch provides wireless perimeter intrusion detection for commercial security and access monitoring systems. Designed for use with compatible Inovonics EchoStream receivers, the transmitter incorporates a side-mounted magnetic reed switch supporting a maximum 5/8-inch (16 mm) magnet gap to monitor the opening and closing of protected doors and windows. The EN1210W also includes an external wired input compatible with standard normally open (NO) or normally closed (NC) security contacts, providing additional installation flexibility. Its integrated case tamper switch detects unauthorized housing access, while fully supervised operation supports ongoing communication monitoring. The transmitter uses Inovonics EchoStream wireless technology to communicate contact status and supervisory information without requiring signal wiring between the protected opening and the security system receiver.

The EN1210W wireless magnetic contact transmitter operates on the 902-928 MHz frequency band using frequency-hopping spread-spectrum (FHSS) technology in North American installations. Each transmitter includes a unique factory-programmed identification number for registration with a compatible receiver and sends supervisory check-in messages every 3 minutes to support communication monitoring. Powered by a replaceable 3V Panasonic CR123A lithium battery, the EN1210W provides a typical battery life of 3 to 5 years and has a specified power requirement of 3 VDC at 60 mA. The compact housing measures approximately 3.5 x 1.7 x 0.9 inches (8.9 x 4.3 x 2.3 cm) and weighs 1.9 ounces (54 grams). Operating specifications include temperatures from -4 F to 140 F (-20 C to 60 C) and relative humidity up to 90% non-condensing. The transmitter meets applicable FCC, ISED, RCM, and RoHS requirements.

The Inovonics EN1210W supports installation on commercial doors, windows, equipment enclosures, and other monitored openings requiring wireless security contact detection. Its built-in reed switch operates with a properly aligned magnet positioned parallel to the transmitter at a distance of no more than 5/8 inch. The external contact input accepts 14-22 AWG unshielded wiring with a maximum cable distance of 10 feet (3 meters) between the transmitter and connected contact. An internal selection jumper allows installers to configure the wired input for normally open or normally closed operation, with normally open selected by default. The reed switch and magnet must be used unless the connected control system specifically supports the reed switch and wired input as separate devices. The transmitter includes a snap-on mounting bracket that simplifies attachment and removal during installation or battery replacement. Compatible Inovonics receiving equipment includes the EN4000 Universal Serial Receiver, EN4200 Security Only Serial Receiver, EN4204R Four-Zone Receiver, EN4216MR 16-Zone Receiver, and EN4232MR 32-Zone Receiver.

Designed for commercial intrusion detection, perimeter monitoring, and wireless security system expansion, the EN1210W provides an alternative to hardwired magnetic contacts where running signal cables is impractical. Its 3-minute supervision interval, integrated tamper detection, and configurable external contact input support security applications requiring identification of transmitter activity and communication status. Installation requires securing the mounting bracket, positioning the magnet within the specified operating gap, installing the CR123A battery, and registering the transmitter with the receiving system. Each contact condition should be tested to confirm the expected response at the security control panel. The EN1210W is intended for indoor installation by professional security technicians, and Inovonics recommends manual testing at least once per week. Unlike the EN1210W-60, which uses a 60-minute supervision interval for senior living applications, the standard EN1210W is configured for commercial security use. The manufacturer's EN1210W Family Installation Instructions (357-00079-01) provide detailed procedures for battery replacement, input configuration, mounting, transmitter registration, and functional testing.
