Exit sign/emergency light combo units
Exit sign combo units are really a 2 for 1 solution and are the ideal solution where you need to install both an exit sign & an emergency light near each other. Exit combos allow you to maintain just one battery and unit while meeting two code requirements. There is a combo exit sign for almost every application and location.
NEMA4X rated emergency products
NEMA rated enclosures are intended for indoor or outdoor use primarily to provide a degree of protection against the entry of water during prolonged submersion at a limited depth. NEMA 12 enclosures are designed to prevent the ingress of dust, water, and oil.
Sealed lead acid (SLA) batteries
Sealed lead acid batteries are sometimes referred to as VRLA (valve regulated lead acid) and there are two primary types AGM and Gel. We offer both AGM and Gel batteries, each has its advantages over the other depending on the specific application. SLA batteries usually last between 3 to 5 years with typical usage. The optimum operating temperature for the lead-acid battery is 25°C (77°F). Elevated temperature reduces longevity. As a guideline, every 8°C (15°F) rise in temperature cuts the battery life in half.
