The Sitewarden RF Pro Site Alarm is a battery-powered, wireless critical alert system purpose-built for construction sites and other temporary or high-risk environments. Combining fire and first-aid alert functions in a single, easy-to-install unit, it delivers powerful audio warnings alongside bright, strobing LED signals to ensure immediate awareness in emergencies. Its fully portable design makes it ideal for rapidly changing site conditions where flexibility is key.

Manufactured by Firechief, up to 63 units can be wirelessly linked to form a comprehensive, site-wide alert network. Any unit can be designated as the master, which is responsible for identifying and announcing which specific unit has been triggered. When the fire alarm is activated, all units emit a pre-recorded warning message, while the master identifies the source of the alert. For first-aid activations, only the triggered unit and the master sound are activated, although the signal is still relayed across all units to maintain full communication coverage.

With a two-year battery life under normal use and no need for fixed wiring or internet connectivity, the Sitewarden RF Pro is both highly reliable and extremely easy to deploy. Its intelligent design and robust performance make it an essential part of any site’s safety infrastructure, offering rapid alerting and clear communication when it matters most.
