This circuit is designed to work together with an existing alarm system that

does not have GSM module.

    

Features:

- Send status change notifications via SMS

- Call on status change to PANIC

- Backup power (9V battery)

- Can handle incoming call and response to DTMF commands:

  - Key 0: Tone response about status (one long signal means status is ARM, two

    short signals means status is DISARM)

  - Key 1: Send status SMS

  - Key 8: Re-initialize modem

  - Key 9: System reset

- Inform about car battery low or disconnected
