How to switch Zummer-GSM between the “Armed” and “Disarmed” modes?
We have implemented 4 ways to do this: 1. With a special button on the unit. We have implemented a time delay (this can be switched off) between pressing the button and switching the unit to the “Armed” mode or back to “Disarmed” mode. 2. With an external button or a Touch Memory key which are attached at your front door. 3. By an SMS-command. 4. By placing a direct call to Zummer-GSM and issuing a DTMF-command.
