Inovonics EN1210 Single Input Universal Transmitter

The Inovonics EN1210 is a fully supervised, single-input universal wireless transmitter designed to connect normally open (NO) or normally closed (NC) security contacts and sensors to compatible Inovonics EchoStream wireless security systems. Operating on the 902-928 MHz frequency band using frequency-hopping spread spectrum (FHSS) technology, the EN1210 provides reliable wireless communication for intrusion detection, door and window monitoring, and remote alarm signaling. The transmitter features automatic supervisory check-ins every 3 minutes, built-in case tamper protection, and battery supervision to help maintain system integrity. Powered by a replaceable 3V CR123A lithium battery with a typical service life of 3-5 years, the compact EN1210 supports external contact wiring up to 10 feet and includes a mounting bracket for straightforward installation in commercial, institutional, and residential security applications.

Inovonics EN1210 EchoStream Single-Input Universal Wireless Transmitter

The Inovonics EN1210 Single-Input Universal Transmitter provides a wireless interface for integrating conventional hardwired security contacts and sensors into compatible Inovonics EchoStream security and alarm monitoring systems. Designed for use with normally open (NO) and normally closed (NC) dry-contact devices, the EN1210 converts contact status changes into wireless signals that can be received and processed by compatible EchoStream receivers. This functionality supports applications involving magnetic door contacts, window contacts, mechanical switches, and other compatible security sensors requiring remote event reporting. The transmitter incorporates fully supervised wireless operation, automatic 3-minute supervisory check-ins, and integrated case tamper monitoring, allowing the receiving system to detect communication interruptions and unauthorized enclosure access. Its compact housing and included mounting bracket make it suitable for commercial buildings, warehouses, institutional facilities, and residential intrusion detection installations where installing new signal wiring is impractical.

The EN1210 operates using Inovonics EchoStream frequency-hopping spread spectrum (FHSS) wireless technology across the 902-928 MHz frequency band in North America. This wireless architecture distributes transmissions across multiple radio frequencies to improve communication resilience in environments containing competing radio signals and structural obstacles. The transmitter measures 3.5 inches high, 1.7 inches wide, and 0.9 inches deep (8.9 x 4.3 x 2.3 cm) and weighs approximately 1.9 ounces (54 g). Power is supplied by a replaceable 3V Panasonic CR123A lithium battery, providing an estimated operating life of 3-5 years under typical conditions. The EN1210 supports external contact connections using 14-22 AWG unshielded wire, with a maximum distance of 10 feet (3 meters) between the contact and transmitter. Manufacturer operating specifications include a temperature range of -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 regulatory requirements for its designated markets.

For intrusion detection and wireless alarm integration, the Inovonics EN1210 provides a flexible single-input interface that can be configured for normally open or normally closed contact operation using its internal selection jumper. When the connected sensor changes state, the transmitter communicates the event to a compatible EchoStream receiver, enabling the associated security control panel or monitoring equipment to respond according to its programmed configuration. The device also transmits supervisory information, including low-battery conditions, enclosure tamper events, and periodic check-in messages, supporting ongoing transmitter monitoring and system maintenance. Compatible receiving equipment includes the Inovonics EN4000 Universal Serial Receiver, EN4200 Security Only Serial Receiver, EN4204R Four-Zone Receiver with Relays, EN4216MR 16-Zone Multi-Condition Receiver, and EN4232MR 32-Zone Multi-Condition Receiver. EchoStream repeaters, including the EN5040 Series, can be incorporated into supported system designs to extend wireless coverage in larger or more challenging installations. Receiver selection, device enrollment, and panel integration depend on the requirements of the complete security system.

Installation of the Inovonics EN1210 universal wireless transmitter begins with mounting the supplied bracket near the external contact or sensor, connecting the input wiring to the internal terminal block, and selecting the appropriate NO or NC input configuration. The transmitter includes a factory-programmed unique identification number, internal reset button, and housing tamper switch to support device enrollment and ongoing monitoring through compatible EchoStream receivers. A supplied 3V lithium battery powers the unit, eliminating the need for a dedicated external power connection. Once registered with the receiver, installers can verify alarm activation, restoration, tamper reporting, and supervisory communication to confirm proper operation. The removable mounting bracket simplifies access for battery replacement and servicing. Unlike the EN1210-60 and EN1210-240 variants, which provide 60-minute and 240-minute supervisory intervals for applications including senior living systems, the standard EN1210 provides a 3-minute check-in interval optimized for security monitoring. By combining universal dry-contact compatibility, battery-powered operation, wireless supervision, and EchoStream receiver integration, the EN1210 provides an efficient solution for extending security monitoring to locations where conventional hardwired connections are inconvenient or costly.
