AO1 SET TO MODE 05, ‘ENABLE/DISABLE DIAL TO OPEN NUMBERS’
When the auxiliary output AO1 mode is set to 05 the dial to open numbers (DTO) will only activate the GSM LITE’s relay when a
common and normally open (CO/NO) switch connected across terminals g & AO1, as shown in Fig.21, is open circuit. When the
switch is CLOSED and terminals g & AO1 are short together this will disable the dial to open numbers (DTO).
