RTN* is the alarm return pin. Alarms on standard units are dry closure or ground closure. Most units will
have RTNinternally tied to GND. However, special hardware assemblies may have RTN isolated from
GND.

ADC** channels 4, 5, 6, and 8 may be unavailable for external use. These analog channels are
sometimes configured in hardware for monitoring Aand B power feeds, internal temperature, and
external temperature.

RTN* is the alarm return pin. Standard configurations have this pin tied to GND. While it is possible to
change this configuration to utilize different types of alarms (i.e. TTL, Open Collector, Battery Closure),
the hardware must be ordered in that configuration. It is NOT field-adjustable.
