- Transfer to Secondary Phone Line -
1) Upon loss of the primary phone line, the panel will energize the on-board relay which will
in turn energize the double pole double throw (DPDT) System Sensor RR1 relay.
2) This DPDT relay will now connect the secondary phone line to the panel. After four (4)
hours (programmable) the on-board relay will de-energize causing the DPDT relay to
reconnect the primary phone line to the panel.
3) If the primary phone line is still not active, then the above sequence will continue until the
primary phone line is restored.
The control panel will automatically switch to the secondary phone line upon loss
of the primary line.
