How many sensors can I connect to Zummer-GSM?

Zummer-GSM has 2 independent input for closed-circuit loops and one analogue input (for instance, for a flood sensor). SMS-message which are sent upon alarms contain information about which input the triggered sensor is connected to. More than one sensor can be connected to a single input. For example, one of our installations saw 8 motion sensors connected to the same input. All the sensors are powered from Zummer-GSM, which means they still work even when the main power is disconnected.
