Would appreciate any advice on the problems below.
Thanks in advance.
I have a Visonic Powermax Pro alarm system fitted with a GSM module and SIM card.
One problem concerns shutdown of the unit when the AC power fails or is manually switched off:
The unit should continue powered-up for a number of hours using the charge from the back-up battery but, unfortunately, after only four minutes the unit switches off and goes dead .
Therefore the unit cannot send the SMS message "AC Power Failure" to my mobile phone because the shortest time before this message can be sent is five minutes.
The battery is the original unit but I have (i) replaced it with a new one and (ii) put both in at the same time as a double back up - with no effect.
Second problem concerns the unit not responding to SMS message instructions sent from my mobile phone:
e.g. if I instruct it to Arm, disarm or give a status report the unit receives the SMS but takes no action.
However the unit will send SMS texts to me regarding any alert or alarm (except "AC Power Failure").
My SMS texts to the unit follow the lines in the manual such as AW "user code" etc.
REMOTE ACCESS is ON.
Thanks in advance.
