What Happens When Commercial Security Alarms Go Off?

By
Amir Anvaridazeh

As a business owner, you more than likely have a commercial alarm system installed on your property. But if you’re like most people, you may not have thought about what actually happens when it goes off.

Without the right response, an alarm only makes noise. It might temporarily scare off trespassers and alert neighbours on its own, but you’ll still need to visit your property, coordinate with police, and manage the aftermath on your own. On the other hand, with an alarm system that enables 24/7 alarm monitoring and remote alerts, you can enjoy the peace of mind of knowing that an operator will dispatch first responders to your property when needed.

This blog will cover the step-by-step process of what happens when a commercial security alarm is triggered at a property protected by Blackbird Tech, and what separates effective responses from less helpful ones.

Key Takeaways

  • A commercial alarm trigger initiates a specific response involving your monitoring centre, designated contacts, and law enforcement or first responders, if necessary.
  • The speed and reliability of that response depend on your security monitoring provider.
  • False alarms are common, and a good provider has a process for handling them without wasting emergency resources.
  • A complete alarm response system utilizes technology and human oversight.

What Triggers a Commercial Security Alarm?

Commercial security alarms are designed to trigger upon detecting signs of break-ins and trespassing, and can be manually triggered in emergencies. These include:

  • Doors and windows being opened while the system is armed.
  • Motion detectors detecting body heat in a secured space.
  • Glass break sensors detecting glass being smashed.
  • Panic buttons that team members can press to contact police, fire, or emergency medical responders, depending on the type of panic button used.

Not all triggers indicate a break-in, which is why it’s important to verify the situation, as we’ll discuss in the next sections.

What Happens After the Alarm Goes Off?

When an alarm goes off, time is of the essence, which is why an efficient response is essential. The following is a step-by-step walkthrough of how the Blackbird Tech monitoring team responds to triggered alarms.

  1. Within seconds of a commercial security alarm being set off, a signal is received by the Blackbird Tech monitoring centre.
  2. An operator initiates the verification process immediately.
  3. The operator calls the client’s designated contacts to confirm the alarm and ask for the passcode.
  4. If a valid passcode is provided, the alarm is cleared, and no further action is taken.
  5.  If no passcode is provided or the alarm can’t be cleared. It’s treated as a real emergency.
  6. Police are dispatched to the property.
  7. A mobile patrol guard may be dispatched as a keyholder to provide first responders with access to the building.
  8. The client is notified about the incident along with any actions taken.
  9. A swift response ensures that all emergencies are handled quickly and appropriately.

Why We Include a Verification Step

False alarms are extremely common in commercial properties, often caused by accidents such as authorized staff members accidentally opening a window while the system is armed or by unauthorized access after hours.

False alarms can strain emergency resources, which is why the best security monitoring providers verify alarms before dispatching first responders. Additionally, the security provider's verification helps protect the client from false alarm fines. It also means that genuine emergencies are handled faster, since less time is spent on false alarms.

What Happens If Designated Contacts Don’t Respond?

If designated contacts don’t answer when an operator calls, the alarm is treated as a real emergency, the same as if the operator doesn’t receive a valid passcode. The operator dispatches police without waiting for confirmation, and a mobile patrol guard may be dispatched as a keyholder for first responders.

At Blackbird Tech, our goal is to eliminate the need for you to attend your property to handle after-hours emergencies. This is one of the primary benefits of hiring a professional security monitoring company, and one of the main differentiators between high-quality monitoring services and lower-cost alarm providers.

How Does the Monitoring Centre Work?

At Blackbird Tech, our 24/7 Monitoring Centre is staffed with operators around the clock. From the centre, our team actively monitors property status and responds to incoming alerts and alarm signals.

Systems installed by Blackbird Tech feature a control panel that effectively serves as the brain of your alarm system and is where triggered alarm signals are sent for our operations team to receive. The control panel communicates through both cellular and internet connections, meaning the system continues to function properly even if phone lines are cut.

Our 24/7 Monitoring Centre team is the added layer that turns hardware into a complete response system, actively protecting your property. Our team is trained to follow protocols and make informed judgment calls when necessary to best protect your business.

What a Complete Commercial Alarm System Looks Like

When combined with active monitoring, a complete commercial alarm system comprehensively protects your property from intrusions, unauthorized access, and break-ins.

The components of a complete alarm system include:

  • Control panel
  • Door and window contacts
  • Motion detectors
  • Glass break sensors
  • Panic buttons with dispatch capabilities
  • 24/7 live monitoring

FAQs About Commercial Security Alarm Systems

What triggers a commercial security alarm?

Commercial security alarms are triggered when doors or windows are opened while the system is armed, motion detectors detect body heat in a secured space, glass-break sensors detect the sound of breaking glass, and panic buttons are pressed by team members. Panic buttons can contact police, fire, or emergency medical responders, depending on the type used.

What happens when a commercial security alarm goes off?

When an alarm is triggered, a signal reaches the Blackbird Tech monitoring centre within seconds. An operator initiates the verification process by calling the client's designated contacts. If a valid passcode is provided, the alarm is cleared. If not, it's treated as a real emergency, police are dispatched, and a mobile patrol guard may be sent as a keyholder to provide first responders access to the building.

What does a 24/7 monitoring centre do?

A 24/7 monitoring centre receives and responds to alarm signals around the clock. When an alarm is triggered, operators initiate the verification process, contact designated client contacts, and dispatch first responders when necessary. At Blackbird Tech, our monitoring centre is staffed around the clock and serves as the human layer that turns your alarm hardware into an active response system.

Do I need monitoring if I already have a commercial alarm system?

Without monitoring, a commercial alarm can temporarily deter trespassers but won't trigger a response from first responders. Professional monitoring ensures that every alarm is verified and responded to, that police are dispatched when needed, and that you don't have to attend your property after hours to deal with incidents yourself.

How do I measure the effectiveness of security measures?
Measuring the effectiveness of security measures involves tracking key performance indicators (KPIs) to evaluate how well systems and personnel are meeting safety and asset protection goals. Start by analyzing incident response times, reductions in theft, vandalism, or shrinkage, and overall resolution rates for reported issues. Comparing pre- and post-implementation data helps demonstrate tangible improvements in safety and loss prevention. Regular audits, surveys, and risk assessment reports can also gauge the reliability and perception of security measures.

Key KPIs to track include:
- Incident response times: Faster responses to alarms or emergencies.
- Reduction in theft/vandalism: Compare loss data before and after implementation.
- Patrol compliance: Track patrol frequency and adherence via GPS or logs.
- False alarm rates: Lower rates ensure focus on real threats.
- Client/Employee satisfaction: Gather feedback to measure confidence in security.
- Client services: Dedicated account representative who supports ongoing needs & can adjust strategy as needed
