Site Alert

Reliable, simple, tough

Standalone alarm systems are ideal for smaller sites where the warning can still be heard clearly in all areas. With the option to hard-wire the stations together to form a network, the Site Alert product is simple yet highly effective.


The Howler Wireless Site Alert fire alarm looks and sounds a bit different to his big brothers, but you’ll quickly discover that he has all the family characteristics – reliable, simple and tough. Designed specifically for smaller construction sites – and smaller budgets – this little guy really means business.

Up to 20 wireless fire alarm units can be linked together and, with voices of 100dB at 1 metre, you’ll find them difficult to ignore when they get going. As far as hard-wired fire alarm systems go, the Howler Site Alert is a fantastic solution.
