And what if someone targeting your property waited until you left, disabled your external sirens in broad daylight in a way that appeared they were in fact an alarm company…. Only to come back of an evening to break in?
The end user comes home notices a tamper on their panel looks at the siren and says oh it looks ok I’ll just reset it…
Some engineer companies will set it so the end user can reset it, some won’t. Either way it should have been made clear to the customer.
I’m sure if you call them they can offer you some advice.
Additionally even if the engineer is required to reset it an active tamper needing reset wouldn’t necessarily stop you using the alarm in the interim until they come to reset that. The engineer may have also set the panel up to allow the alarm to continue to be used during an active tamper, or they may have set it to lock the end user out until resolved.
The possibilities with professional systems are literally endless.
