3.8.1 Master Code Switch

1. The master code switch is left in the off position for normal operation. Turn the master

code switch on when setting the system master code. See programming instructions to

set the system master code. If the master code switch is turned on and a new master

code is not entered, the system will sound a long tone after approximately 30 seconds.

This tone will continue every 30 seconds until a new master code is entered, or until the

switch is turned off.

3.8.2 Ring Pin

1. The ring pin is labeled RING on the control board. This shorting pin must be installed to

allow the system to answer any calls placed to it. If remote programming or remote relay

operation is to be used, the shorting pin must be installed. Removing the shorting pin will

cause the system to never answer any call placed to it.

3.8.3 Relay 2 Contact Pin

1. This shorting pin sets the contacts on relay number two to be set to either Normally Open

(NO) or Normally Closed (NC). The pin is set to NO from the factory.
