Site Alarms

Site Alarms allow manual alarm systems to be installed where an automatic detection system is not feasible or not yet connected. These temporary site fire alarm systems can be used to raise the alarm in any emergency that requires evacuation of the site. Our site alarms can be used and activated following dangerous incidents such as chemical spills as well as fires. A site alarm can therefore be installed on construction sites and temporary structures for example container accommodation, and at outdoor venues such as music festivals, outdoor events, and campsites.

Visit our help guide for more information about manual fire alarm use.

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.
