Commercial alarm systems for small businesses: A guide

Protecting your property and staff is vital for your company. Learn about business security systems here

All companies need a way to ensure the safety of their staff and premises – and that’s why business alarm systems are essential. While the type and use of an alarm can vary, what remains the same across the range of business security systems is that an alarm is there to deter potential intruders and alert staff to possible dangers. If the worst should happen and your business experiences a break-in or a fire, then an alarm is often the quickest way to know about it.

This article will look at both security and fire alarms. To begin with, more information about the different types of alarms will be provided. Then, a detailed look at some top business alarm companies, including product information, will be offered.

Each of the following common questions will be answered:

What are commercial alarm systems?

A vital part of your operational strategy, commercial alarm systems provide added security against damages, plus offer additional safety for your staff too. Offering extra security if any of your contents (physical or digital) are stolen or vandalised, business alarms are an excellent way to deter would-be intruders and protect your company’s assets, giving you peace of mind.

To begin with, here’s a quick guide to some of the most frequently used abbreviations:

Alarm Receiving Centre (ARC) – For monitored business alarm systems; the security company’s centre which monitors the alarms and investigates if they are triggered.

National Security Inspectorate (NSI) – A leading organisation in the UK for security and fire protection company certification. NSI offers two tiers of awards – Silver and Gold.

Police Unique Reference Number (URN) – A specific number attached to a property, enabling it to be identified by the police. Used when an alarm has been triggered and the ARC has informed the police that their response is required. Only available to alarms that have been installed by UKAS accredited organisations.

Security Systems and Alarm Inspection Board (SSAIB) – A certifying body for organisations offering security protection, including alarms; it’s a UK-based leading organisation.

United Kingdom Accreditation Service (UKAS) – The only national body in the UK to assess organisations that offer certification and installation. It’s recognised by the government and tests to globally recognised levels. The NSI and SSAIB are UKAS accredited.

There are many business alarm companies out there and choosing the right one for your business is a crucial decision. Useful points to consider include:

  • Accreditation – Is the company approved by the NSI or the SSAIB?
  • Specialisation – Can the company offer business security alarms specifically?
  • Recommendation – Does the company have a positive reputation, both within the industry and with customers?

Once you’ve reviewed these, it’s time to think about which alarm system is best for your business.

Business alarms – how to choose:

  • Think about how it will be installed – Is a wired or wireless system more suitable?
  • Consider the type of connectivity – Can it be combined with an app?
  • How is the signal received – Internet (IP), mobile (GPRS) or radio?
  • Look at the response time – How quick is the process from activation to notification?
  • Check the visual aspect – Are alarm boxes, cameras and warning stickers available to be displayed prominently?
  • Which way of monitoring is best – Do you require an alarm system that connects to an ARC, or is a more simple bell-only device needed?
  • Review the costs – How much and how long is the contract length; what are the installation and maintenance charges, and are they included?

The NSI and the SSAIB are the two leading certification organisations in the UK for companies that offer fire and security protection. It’s important that the company you choose is approved by one of these organisations so you can be sure that the system installed in your business adheres to the required best practice as well as relevant codes and legislation.

Business alarm systems: what are the benefits?

The benefits for your business are wide-ranging. With an alarm installed in your business, you have an additional layer of security that’s always available. Plus, it’s not open to human error that you may experience with only using security guards, as alarms use sensors to detect movement.

In the first instance, an alarm can deter people from breaking in to your premises. If an intrusion should occur, then the alarm immediately alerts others in the vicinity of an issue. Plus, if you choose to have the monitored system, then the ARC will investigate, and if applicable, inform the police or other emergency responders.

Not only do alarms protect your property, they also can be used to monitor staff work times so you know exactly who is coming and going, and when.

Also, consider commercial alarm systems that have smart technology. For example, an app that you can monitor the system on remotely. This is ideal if you’re overseas, or if you spend a lot of time away from your business premises, as you only require your device and an internet connection to access it.

  • 24/7 security
  • Sensors detect movement
  • Act as a deterrent
  • Alerts others through sound and lights
  • Monitored systems connect to ARCs for investigation or referral
  • Follow staff work times
  • Connect to alarm activity remotely via an app, if possible

If you run a business from home, then you should also consider the physical security of your workspace. You could check with the alarm company as well as your insurer to see if commercial alarm systems are required, or if a domestic alarm will suffice. This could depend on the type of business you run from home, as well as also if you store goods or other valuable products, and other factors.

Why are commercial fire alarm systems essential?

Another integral part of your business’s security systems are commercial fire alarm systems. These should be a part of your wider fire safety strategy – this includes conducting a Fire Risk Assessment and having a Responsible Person (if your business has five or more employees) for fire security. This is determined by the relevant legislation, the Regulatory Reform (Fire Safety) Order 2005.

When choosing a fire alarm for your business, think about which type is most suitable. Depending on the size of your premises, an alarm with a zoning system may be required – this sections the property, allowing for any incidents to be dealt with in a focused and controlled manner. Alternatively, an alarm without zoning could be used in smaller sized spaces.

You may also want to think about emergency lighting – this is crucial if the mains power should go out during a fire. Also, fire extinguishers are a key part of a business’ fire strategy. Think about which types your business would most likely need. For example, a specific electrical fire extinguisher for a business with a lot of electrical equipment.

Whichever system you choose, it’s extremely important to regularly test the alarms and conduct fire drills, as well as record the results. This allows you to know that the alarm systems in your business are working correctly and that you’re operating in the most safe and secure manner should a fire occur. Plus, if a fault or another issue should be identified, you can address it immediately.

Types of commercial fire alarm systems

Commercial fire alarm systems are typically made up of all or some of the following parts:

  • Panels – The control panel which connects the parts together
  • Detectors – The devices which identify a fire
  • Manual call points – Wall-mounted boxes; people can activate these upon finding a fire
  • Sounders and flashers – Audio and visual devices that go off when the alarm has been triggered

What types of systems are available?

Conventional system – A series of call points and detectors are wired to a control panel, with sounders and flashers to notify people when activated. The area is divided into zones and it’s possible to locate in which one a fire has started.

Addressable system – Similar to a conventional system. The key difference is that with an addressable system it’s possible to identify the exact call point or detector where the alarm was raised.

Analogue addressable system – Offers more comprehensive coverage due to the increased number of detection and notification devices that can be connected. They’re particularly suitable for large premises, such as a warehouse. In addition to the size of the property, a key reason for choosing this system is to reduce or prevent false alarms.

Wireless system – An analogue addressable system that doesn’t use cables. The key difference is that the components, such as the call points and the smoke detectors, along with the sensors, connect with the control panel wirelessly with radio signals. More detail about wireless systems is provided in the next section.

Commercial wireless fire alarm systems: pros and cons

An initial concern with commercial wireless fire alarms was with the reliability of the radio signalling they used. This technology has improved over time though and these systems offer the security and safety of traditional systems, alongside the improved visual aspect. This is especially useful for businesses that have a visually strong brand and don’t want wires to disrupt carefully designed spaces.

Higher set-up costs than traditional systems
