Combo Unit, Black, Steel, Chicago Approved, Sealed Lead Acid (SLA) Products (4 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.

The main housing of these exit signs and emergency lights is painted black or made from a black thermoplastic.

Tough steel exit signs are the ultimate in durable, impact-resistant exit signage & emergency lights. Available in New York and Chicago approved models, these signs features a universal canopy and LED lighting.

Chicago Approved exit signs must meet specific rules and guidelines. Signs must be rectangular 20 gauge sheet metal with a glass or plastic face. The letters and arrows must be red on white. All exit signs must be internally illuminated with at least a 10 watt lamp.

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.
