Combo Unit, Hazardous Location, Sealed Lead Acid (SLA) Products (6 items)

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.

Hazardous location exit signs and emergency lights are designed to operate in hostile environments that would damage ordinary signs and lights. Constructed from corrosion resistant materials, some units offer sealed enclosures that can be used in outdoor environments or areas subject to water spray, moisture and extreme temperature conditions.

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.
