When the alarm system is activated our Alarm Receiving Centre will attempt to contact the home owner, if the owner can not be contacted, the keyholder will be called.

Being a keyholder is easy. Just ensure you instruct them on the following information:

• The correct entry/exit route to your property
• How to unlock the property
• Where the home protection system panel, keypad and proximity reader are located
• How to set and unset the monitored home protection system and the system code/password (keyholders can have their own code assigned) The telephone number of the ADT Customer Service Centre 
• The telephone number of ADT's Service Bureau, to request an engineer if required
• How to contact the homeowner
• Where the log book is kept
• How to reset the alarm
• How to lock up again
• You can help your keyholders by allowing them to set & unset your home protection system when they come to visit.
