Table 3 MR-2300-PR jumper settings
The Alarm Transmit signal to the MR-2300-PR can be programmed to turn OFF when signal
silence is active. This allows the City Tie Box to be manually reset. On subsequent alarms the
silenceable signals will resound and the City Tie Box will be retriggered. See section 11 on
page 53 for more information.
The Trouble Transmit signal to the MR-2300-PR can be programmed to delay AC power fail
for 0 to 3 hours if this is the only system trouble. See section 11 on page 53.
Note: Relay programming should be done before installing the board.
