The alarm going off at 2am is one of those business events that everyone hopes never happens — and almost nobody has a proper plan for. Most businesses have an alarm. Most businesses have an alarm monitoring company. Fewer businesses have a clear, documented, and professionally delivered response protocol for what happens next. A professional key holding and alarm response service removes the ambiguity entirely, but understanding what a proper alarm response looks like is useful whether you are reviewing your current arrangements or specifying a new service.
The overwhelming majority of commercial alarm activations — well over 90 per cent, according to both industry practitioners and published research — are false alarms. Common causes include power surges, insects triggering passive infrared sensors, poorly calibrated detectors, cleaning staff arriving at unusual hours, and temperature fluctuations affecting thermal sensors.
It is entirely natural, given this reality, to begin treating activations as probably-false until proven otherwise. This is the habit that causes accidents. Every activation must be treated as a genuine intrusion until a trained person has attended the premises and confirmed it is not. The one time you assume it is a sensor fault is the time it is not.
If your current arrangement involves a nominated internal keyholder attending alarm activations, this is the step that presents the greatest risk. An untrained member of staff attending a premises that may have been broken into — alone, at night — is placing themselves in a situation they are not equipped to manage safely.
A professional security officer attending the same activation brings a fundamentally different capability. They are trained in situational awareness and dynamic risk assessment. They know how to approach a potentially compromised premises. They have protocols for coordinating with police. They do not place themselves in danger unnecessarily. And critically, they have backup — via a 24/7 control room that is tracking their attendance in real time.
The correct approach, if you do not have a professional key holding service in place, is to wait for a trained response before anyone enters the building. This may feel counterintuitive, particularly if the alarm monitoring company is applying pressure to confirm or deny. The risk of sending an untrained person in first is considerably greater than the risk of waiting.
When a professional key holding provider manages your alarm response, the process operates as follows:
Activation received. Your alarm monitoring company or the key holding provider’s own control room receives the activation signal from your alarm system. The time is logged immediately.
Officer dispatched. A SIA-licensed officer is dispatched to your premises. Response times will vary depending on your location and the provider, but a professional service will have agreed response windows as part of your contract.
External inspection first. The responding officer assesses the exterior of the premises before entering. Signs of forced entry, broken glass, open doors, or suspicious vehicles or individuals in the area are all noted and reported before any entry is made. If there is an active threat, the officer coordinates with police rather than attempting to intervene.
Internal inspection. Once it is safe to do so, the officer enters and conducts a thorough internal check, moving systematically through the premises to identify any unauthorised access, damage, or suspicious activity.
Site secured. Whether the activation proves to be a genuine intrusion or a false alarm, the officer secures the premises before leaving. If there has been a break-in, this may involve boarding up a damaged entry point, awaiting police, or arranging emergency repair services.
Incident report issued. You receive a written report detailing the time of the activation, the officer’s attendance time, observations made during the inspection, actions taken, and any recommendations for follow-up. This report is important for your own records, for any insurance claim, and potentially for a police investigation.
Commercial property insurers take alarm response seriously. Many policies contain conditions that require alarms to be responded to promptly by a competent person — and some policies specifically require that response to be carried out by a professional key holding service rather than an untrained internal keyholder.
In the aftermath of a break-in or fire, insurers will want to understand how the alarm was managed. A documented response from a professional, SIA-approved key holding provider — with timestamped records of the activation, the officer’s attendance, and the actions taken — is a materially stronger position than an informal arrangement.
If you are claiming for stolen plant, damaged stock, or structural repair following a break-in, the quality of your alarm response documentation can directly affect the outcome of that claim.
The time to review your alarm response arrangements is not after an incident. A few straightforward questions will establish whether your current approach is fit for purpose:
If any of these questions produce an uncomfortable answer, the arrangement needs reviewing.
