Alarms

About Alarms

Alarms are critical security and safety devices designed to detect and alert users to potential threats such as intruders, motion, or unauthorised access. MyToolShed.co.uk supplies professional-grade alarm systems suitable for construction sites, workshops, retail premises, warehouses, domestic properties, and commercial facilities across the UK. These systems provide essential protection for tools, equipment, and premises, helping tradespeople and property owners prevent theft and unauthorised entry. Modern alarm technology has advanced significantly, with wireless systems offering flexible installation without complex wiring, whilst motion-sensing capabilities provide reliable detection with minimal false alarms.

The alarm category at MyToolShed includes motion sensor alarms, PIR (Passive Infrared) detection systems, wireless alarm units, and portable security devices. These products are particularly valuable for tradespeople working across multiple sites, site managers protecting valuable equipment overnight, and homeowners seeking cost-effective security solutions. Battery-powered and mains-operated options are available, with many contemporary systems featuring adjustable sensitivity settings, multiple alarm tones, and easy mounting solutions for both temporary and permanent installations.

Applications

• Builders and Site Managers: Protecting construction sites, tool stores, and valuable equipment from theft overnight and during unmanned periods
• Electricians and Tradespeople: Securing vans, mobile workshops, and temporary site cabins containing expensive tools and materials
• Warehouse and Facilities Managers: Monitoring access points, storage areas, and restricted zones within commercial and industrial premises
• Retail and Shop Owners: Detecting customer movement in specific areas and alerting staff to potential security concerns
• Landlords and Property Managers: Protecting vacant properties, garages, sheds, and outbuildings from break-ins
• Homeowners and DIY Enthusiasts: Enhancing domestic security for garages, workshops, garden sheds, and home entry points
• Security Professionals: Installing standalone alarm systems as part of comprehensive security solutions

Choosing The Right Alarms

When selecting alarm systems, first determine the environment and application. For outdoor use or construction sites, choose weatherproof units with appropriate IP ratings that withstand exposure to dust and moisture. Indoor applications allow for standard units with adjustable sensitivity to suit different room sizes and detection requirements.

Power source is a key consideration. Battery-operated wireless alarms offer maximum flexibility for temporary installations or locations without mains power access, ideal for site cabins and outbuildings. For permanent installations with 240v mains access available, hardwired systems provide continuous operation without battery replacement concerns. Many professional users prefer wireless systems for ease of repositioning as site layouts change.

Detection range matters significantly—PIR motion sensors typically cover areas from 3 to 10 metres, with coverage angles varying from narrow focused beams to wide 110-degree detection zones. Consider the size of the area requiring monitoring and any obstacles that might create blind spots. Adjustable sensitivity settings allow fine-tuning to minimise false alarms from pets or environmental factors whilst maintaining effective intrusion detection.

Volume and alarm tone should be appropriate for the environment. MyToolShed.co.uk stocks alarms ranging from 90dB to over 120dB output—louder systems suit noisy construction sites or large premises, whilst moderate volumes work well for domestic applications. Look for systems with multiple tone options or adjustable volume settings for versatility across different scenarios.

Frequently Asked Questions

What's the difference between PIR and standard motion sensors?

PIR (Passive Infrared) sensors detect changes in infrared radiation caused by body heat from people or animals moving within the detection zone. This technology is more reliable than basic motion detection, producing fewer false alarms from moving objects like curtains or shadows. PIR sensors are the professional standard for security applications, offering superior accuracy whilst consuming less power than active scanning systems.

Can wireless alarms be used on construction sites?

Yes, wireless alarms are particularly well-suited to construction sites where mains power may be unavailable and flexible positioning is essential. Choose ruggedised models with weatherproof housings rated IP65 or higher to withstand site conditions. Battery-powered units eliminate trailing cables that create trip hazards, and they can be easily relocated as site layouts evolve. Ensure regular battery checks are part of your site safety routine.

How do I prevent false alarms from my motion sensor?

Position sensors away from heat sources like radiators, air conditioning vents, and direct sunlight, as temperature fluctuations can trigger PIR detectors. Adjust sensitivity settings according to the monitored area size—higher sensitivity suits large spaces but may cause false triggers in smaller rooms. Mount sensors at the recommended height (typically 2-2.5 metres) and angle them to avoid detection zones passing through windows where moving trees or passing traffic might activate the alarm.
