The ultimate alarm reporting and remote control system gives you flexible and programmable monitoring of virtually any alarm condition. These communicating annunciators support alarm inputs from open or closed contacts, voltage changes, loss of data transitions, and changes in control lead status. Models are also available that can monitor for unique data streams. Sixteen independent relays form C relay contacts can be remotely controlled or used to echo alarm inputs. Alarm status of each channel is displayed by red or green LEDs. An audible buzzer and master alarm relay provides summary status for all sixteen circuits.

Annunciators can be used independently, in pairs over a communications channel for bi-directional alarm reporting, or in a polled or dial-up network.
