Telegraph codes unique to each of the sixteen zones for Trouble, Alarm and Secure as well
as Low Battery and AC Power Fail are transmitted over a 100 milliampere circuit using
PNIS (Positive Non-Interfering Successive) or SNI (Serial Non-Interfering). The DET-16
has line current detection to avoid clashes between more than one transmitting device.
Automatic ground return, a Watch Dog Timer, and a trouble buzzer assure continued main
system operation and operator notification in the event of a box failure.

Transmission speed is adjustable to match existing decoding units, as are the number of
digits for the box number and the last digit for alarm, trouble, and restore. Number of rounds
for each condition is also programmable.
Automatic switchover to battery power is performed upon AC power loss with a low battery
code transmitted if power is not returned in approximately 70 hours (when the battery
voltage drops below 10.5 volts). When the battery voltage drops below 9.5 volts, the unit
bypasses all input circuits to avoid spurious transmission of false alarms.
