An alarm activation at a property you cannot reach is one of the more unsettling experiences of second-home ownership. It could be a fault, a false trigger, an intruder or a response to something more significant. Without a plan, the default is a phone call to a neighbour who may or may not be available, or a two-hour drive on incomplete information.
Why alarms activate at vacant properties
The most common causes of alarm activations at unoccupied properties are not intruders. They are sensor faults due to insects or dust, low battery warnings, disruption to communication channels, or in older systems, general electrical instability. A small number of activations are triggered by movement caused by structural settlement, thermal expansion of window frames, or wind-induced vibration in exposed positions.
None of that makes the activation less urgent. Until someone is physically at the property, you cannot know which it is.
The distance problem
For most Cornwall second-home owners, the property is two hours away on a good day. An alarm activation at 11pm on a Tuesday means either a long drive on incomplete information, or waiting until morning and hoping for the best. Neither is a satisfying position. And if the activation does indicate a break-in or structural problem, time matters: both in terms of what can be taken or damaged, and in terms of the police response window.
The police will attend a confirmed intrusion. They will not always attend a lone alarm activation at an empty property, particularly in an area with a significant second-home population where false alarms are common. If you want a response, someone needs to be there to verify and, if appropriate, call it in.
What a professional response looks like
With a key holder and a local contact briefed on your property, an alarm activation triggers a different process. Your key holder attends the property, typically within 30 to 60 minutes, and carries out a physical check of all access points. They can silence the alarm, assess whether anything has been disturbed, and call the police if there is evidence of entry. If the activation is a fault, it can be assessed, the alarm company called and a contractor arranged in the morning. If it is a genuine intrusion, they are on site when the police arrive.
In every case, you receive a report of what was found and what was done, before you have had to leave your house.
Insurance and alarm activations
Most insured properties are required to have an operational alarm and a nominated key holder or monitoring service. Some policies specify that the key holder must be able to attend within a set time, typically 20 to 30 minutes. If your alarm activates and no one attends, and the property is subsequently found to have been entered, there is a risk the insurer will argue that the key holding requirement was not met. Check your policy wording.
Having a plan before it happens
The decisions to make before an activation, not during one, are: who holds a key, how they are reached, what they are authorised to do, and what information they have about the alarm system. A key holder who does not know the alarm code is of limited use at midnight.
A professional key holding service takes the decision-making out of an already stressful moment. The property is known, the alarm system is documented, the process is established and the reporting is automatic. The call at midnight becomes a notification in the morning telling you what happened and what was done.
