Testimonials

"

I now require this protection for all bar/nightclub or similar assembly occupancies and have virtually eliminated malicious false alarms at these locations. I strongly recommend these products in most new construction where a potential problem exists, such as daycares, schools, children’s medical facilities (pediatric clinics and dentist offices), or where accidental activation may occur due to increased activity or work at or near the pull stations. Great products that simply make great sense!
