The EN1243 Smoke/Heat Detector-Transmitter provides residential grade smoke and heat detection and includes the Inovonics EchoStream platform as well as GE Interlogix CleanMe technology. The EN1243 includes two batteries, providing up to five years of operation.
System overview
Powered by Inovonics
The Inovonics EchoStream platform, powered by Inovonics wireless mesh network technology, ensures superior range, reliability, and scalability for residential and commercial applications. Using a wide range of transmitters and repeaters, this proven technology provides flexibility and performance to meet the most stringent requirements. This exclusive protocol is available only on Inovonics EchoStream products.
Wireless 900 MHz Band
The Inovonics EchoStream platform sends redundant information on several multi-frequency channels within the FCC Part 15 900 MHz band, providing superior range and reliability. In comparison, systems that use a
single frequency technology can only send information on one narrow band channel. Any interference within the band can cause missed signals.
Functions
Supervision
The battery activity and radio link are supervised. Monitoring helps ensure reliable operation.
Monitored CleanMe Signal
The CleanMe signal indicates when the smoke detector is out of specification, increasing system integrity and reducing false alarms. CleanMe selfdiagnostics monitor the detector’s sensitivity and operational status. If the detector drifts out of the desired sensitivity range or fails internal diagnostics, it extinguishes its LED and sends a signal to the receiver.
Disposable Block Chamber
The disposable chamber allows for on-site cleaning, eliminating the need to send detectors to the factory for cleaning.
