Take the case where an intruder alarm operates in silent mode or delayed siren mode and a key holder is immediately notified to attend.
The key holder may on arrival find the intruders still on the premises and this could present a serious risk to the key holder.
Delayed siren or fully silent alarms are acceptable if the priority is the arrest of the un-suspecting criminals before they leave the premises.
But for a keyholder without adequate support to approach the premises while the intruders are on scene and un-aware that they have been detected is not a sensible thing to do.
