The ALERT120 is an advanced store and forward repeater for ALERT (legacy) networks. In addition to repeating ALERT packets, the ALERT120 can act as a full remote station with six sensor inputs via standard circular connectors, as well as two cable glands for additional inputs. The ALERT120 uses the RF500M modem and the CR800 datalogger, which provide advanced features such as the ability to log traffic.

The modular design of the ALERT120 transmitter allows for alternate configurations, additional peripherals, and easy replacement of individual components. Because the ALERT120 is built around the CR800 datalogger, many additional communications options are available. The ALERT120 can be converted from an ALERT repeater to a standard ALERT station with a simple software setting, or the ALERT120 can be converted to an advanced ALERT2 station by replacing the RF500M with an AL200.
