Inovonics EN1224 Multiple Condition Pendant Transmitter

The Inovonics EN1224 is a four-button, multiple-condition wireless pendant transmitter designed for security signaling, alarm activation, and remote event notification. Operating on the 902-928 MHz EchoStream wireless platform, the transmitter uses frequency hopping spread spectrum technology to communicate distinct button conditions to compatible receivers and application controllers. Featuring four individually identifiable buttons, LED transmission confirmation, and a 3-5 year battery life, the EN1224 supports portable belt-clip use or fixed-position mounting in commercial security applications.

Inovonics EN1224 EchoStream Four-Button Multiple-Condition Wireless Pendant Transmitter

The Inovonics EN1224 Multiple Condition Pendant Transmitter provides wireless signaling for commercial security systems requiring identification of distinct alarm conditions or control events from a single device. Featuring four numbered activation buttons, the transmitter communicates separate conditions to compatible Inovonics EchoStream receivers and application controllers. Its 902-928 MHz frequency hopping spread spectrum (FHSS) technology provides wireless communication across the North American EchoStream frequency band. The compact transmitter supports portable operation with a compatible belt clip or fixed-position installation, making it suitable for security personnel, facility monitoring stations, and other locations requiring multiple wireless event inputs.

The EN1224 measures 3.0 x 1.6 x 0.72 inches (7.6 x 4.0 x 1.8 cm) and weighs approximately 2 ounces (57 g), providing a compact housing for handheld or belt-mounted operation. It operates using a replaceable 3V Panasonic CR2 lithium battery, Inovonics replacement part BAT608, with a typical service life of 3-5 years under normal operating conditions. The transmitter supports ambient temperatures from 32 F to 140 F (0 C to 60 C) and relative humidity up to 90% noncondensing. An integrated LED flashes during wireless transmissions to provide visual confirmation of button activation. The transmitter sends automatic supervisory check-in messages every 3 minutes, allowing compatible receiving equipment to monitor communication status.

The Inovonics EN1224 integrates with the EN4000 Universal Serial Receiver, EN4200 Security Only Serial Receiver, and EN6040 Network Coordinator for communication with compatible security and monitoring systems. Each pendant includes a unique factory-programmed identification number that enables individual registration and supervision through the receiving application. The transmitter supports multiple condition messages, including simultaneous signaling when the application controller is designed to recognize the corresponding events. Its four-button configuration allows separate alarm or control functions to be assigned according to the receiving system's programming. The EN1224 requires compatible serial receiver or network coordinator infrastructure and is not intended for direct operation with standard Inovonics add-on receivers.

The Inovonics EN1224 EchoStream Pendant supports security and facility monitoring applications requiring multiple wireless signaling functions without hardwired activation devices. Its four-button design, supervised wireless communication, replaceable battery, and visual transmission indicator provide flexible operation for portable and fixed-position installations. The housing accommodates the optional ACC605-BK10 black belt clip accessory, while battery replacement and geographic frequency configuration are accessible through the removable cover. Manufacturer documentation identifies FCC and RoHS compliance and a limited 36-month warranty against defects in materials and workmanship, subject to warranty terms. Installers should verify receiver compatibility, application controller support for multiple conditions, transmitter registration, and wireless signal coverage before deployment.
