Business intruder alarms

Intruder alarms are essential in business for providing security and protecting what matters. Intruder alarms should be installed by an NSI Gold industry approved security provider and include being linked to a British Standards approved Alarm Receiving Centre (ARC) for professional monitoring and reassurance that if needed all alarm activations can be passed quickly to the police and key holders to deal with any incidents. SECOM has its own dedicated BS5979 Control and Command Centre offering additional services along with its own Intelligence and Investigations Unit delivering a unique approach to security.

SECOM’s intruder alarms are continuously monitored via the latest technology signalling devices in our dedicated Control and Command Centre. There’s always someone watching over your premises, ready to respond to alarm activations and in the event of a break-in, will notify keyholders and the emergency services to minimise any disruption or loss to your business.

Police response


Police forces throughout the UK do not automatically respond to intruder alarms unless the system has been installed by an NSI approved company and carries a valid police unique reference number (URN) issued by the relevant police authority. SECOM can provide police response systems, which in the event that an alarm is triggered, or personal attack button activated, we’ll immediately contact the authorities. SECOM’s alarm monitoring service means our trained professionals can assess the situation and take the appropriate action.

Professional keyholder response


SECOM can also provide a professional keyholder response service and if your alarm is activated and you are unavailable, we will dispatch a Security Industry Authority (SIA)-licensed officer to inspect your property and reset the alarm. We’ll ensure the property is secure and then send you a full report. This enables business managers and owners to relax during out-of-work hours safe in the knowledge the security experts are taking care of any situation that may arise.

At SECOM we pride ourselves on our customer service and will ensure you fully understand your security solution. This includes outlining the processes in place and steps taken in a number of scenarios, as well as being upfront about installation and monitoring costs.

Business security systems


All of SECOM’s intruder alarms meet police and insurance PD6662:2017 and BS8243:2010 standards and can be fitted with the latest detection technology. This can range from window sensors and magnetic contacts to movement and vibration detectors to provide maximum protection.

We offer both wired and wireless integrated intruder alarm systems with passive infrared movement sensors, panic buttons, control panels, CCTV cameras, and shock and smoke detectors for an increased level of security. Your SECOM engineer will be able to explain how all of these elements work together to keep your business safe.
