Site Alarms

Building sites face unique fire safety challenges that standard domestic alarms simply can't handle. Construction environments require robust and reliable fire detection systems that operate effectively in the presence of dust, noise and harsh conditions. Weather is also a factor, and site alarms often need to be able to operate over a large area.

What makes site alarms different from regular fire detectors?

Site alarms are built to withstand the rigours of construction environments. They feature weatherproof casings, enhanced sensitivity settings, and wireless connectivity that works across large areas. Unlike home smoke detectors, these systems can operate in dusty conditions without constant false alarms.

Construction sites generate dust, debris, and various particles that would trigger standard detectors repeatedly. Site-specific alarm systems use advanced filtering technology to distinguish between actual fire threats and construction-related particles.

How do wireless site alarm systems work?

Wireless site alarms create a network of interconnected detectors, call points and sounders across your construction site. When one detector identifies a fire risk, it immediately alerts all connected units simultaneously. This ensures everyone on site receives the warning, regardless of their location.

The wireless technology eliminates the need for complex wiring installations. You can position detectors wherever needed and relocate them as your project progresses. Battery-powered units provide months of operation without external power sources.

Which fire detection technology is most effective for construction sites?

Heat detection proves most effective for construction environments. These detectors respond to rapid temperature changes rather than smoke particles, making them ideal for dusty conditions. They trigger when temperatures reach preset levels or rise rapidly.

Optical smoke detectors work well in enclosed areas, such as temporary offices or storage containers. Combined heat and smoke detectors offer dual protection for critical zones where both detection methods add value.

Are there specific regulations for construction site fire detection?

Construction sites must comply with building regulations and health and safety requirements. The Construction (Design and Management) Regulations mandate adequate fire safety measures throughout the construction phase.

Your fire detection system should meet British Standards for construction site safety. Regular testing and maintenance ensure compliance and optimal performance. Many insurance policies require the use of certified fire detection systems for construction projects.

How many detectors does a typical construction site need?

Coverage depends on your site size, layout, and specific risk areas. A general rule suggests one detector per 100 square metres for open areas. High-risk zones, such as fuel storage or electrical equipment areas, require additional coverage.

What maintenance do site alarms require?

Site alarms need regular testing to ensure reliable operation. Weekly tests verify battery levels and detector sensitivity. Monthly inspections check for physical damage from construction activities.

Replace batteries according to the manufacturer's guidelines, typically every 6 to 12 months. Clean detector sensors monthly to prevent dust accumulation. Document all maintenance activities for compliance records.

Frequently Asked Questions (FAQs)

Can site alarms be used for emergencies other than fires?

Yes, site alarms are designed to work for any emergency requiring evacuation or for alerting to a first aid emergency. They can be activated during chemical spills, violent incidents, or other dangerous situations. This versatility makes them valuable for construction sites, festivals, and temporary venues where multiple hazards exist.

What's the wireless range for modern site alarm systems?

Advanced systems, such as the Evacuator Synergy+, can connect up to 250 devices across a 2 km range. This wireless capability eliminates the need for complex wiring and allows flexible positioning as your site layout changes during construction phases.

Are simple manual alarms sufficient for small construction sites?

For small sites, basic options such as alarm triangles, megaphones, or rotary bells may be sufficient. However, your risk assessment determines the appropriate level of complexity. Larger construction sites typically require more sophisticated interconnected systems for comprehensive coverage.

Do any site alarms feature a first aid alert?

Some specialist units, such as the Evacuator Synergy+ system, include dedicated first aid buttons. When pressed, these devices send location-specific alerts to the base station, allowing first aid support to be dispatched quickly to the exact location of the person needing help.

When should construction sites install temporary alarm systems?

Construction sites should install temporary alarms from the earliest stages when permanent fire detection systems aren't feasible. These systems bridge the safety gap during construction phases, ensuring compliance with fire safety requirements and protecting workers and site visitors until permanent systems are connected.

Temporary fire alarm systems for construction sites

Temporary fire alarm systems for construction sites

Construction sites pose a challenge for standard fire safety recommendations, as during early construction, it is not possible to install a suitable fire detection system. While the FSO and Building Regulations require 'suitable' fire detection and alarm systems, and compliance with BS 5839 is recommended, these standards apply only to completed buildings, leaving a gap for construction sites. To address this, manually activated site alarms can be used throughout the site until a permanent system is installed. This ensures essential fire safety measures are in place during construction.

For more information about the appropriate use of temporary site alarm systems, read our blog.

Wireless manual site fire alarms

Wireless manual site fire alarms

Manual site fire alarms come in many forms. At their simplest, an Alarm Triangle and Striker, Megaphone, or Rotary Alarm Bell may be deemed suitable wireless options for small sites, such as campsites or small outdoor work sites. For larger settings, such as construction sites and music festivals, more complex systems may be deemed necessary by the risk assessment. Where the range of these systems have previously been limited by wires, newer models such as the Evacuator Synergy+ range enable wireless connections of up to 250 devices over a 2km range.

Site alarms for emergency evacuation and first aid

Site alarms for emergency evacuation and first aid

As well as providing a way to manually raise the alarm in the event of a fire, site alarms can be activated in other dangerous emergencies, such as chemical spills, or violent attacks at a venue. This ensures that staff and visitors are warned of danger and the need to evacuate, while alerting the site manager to the need to respond accordingly.

Further to this, some specialist call points, such as Evacuator’s Synergy+ unit are fitted with a dedicated first aid button. When pressed, an alert will display on the system base station providing the location of the activated unit, so that first aid support can be sent to the person in need.
