Russo Fire Provides full service of Emergency Lighting Systems from Self-Power Exit Signs to Centralized Emergency Lighting Systems. Emergency Lighting Systems are extremely important and require proper servicing and maintenance to ensure they will function in a power outage.

Emergency Lighting Systems are used to provide lighting to a means of egress during an emergency condition and to visibly identify Exits. This allows people to see where they are going, and safely locate an exit from the building.

There are two basic layouts for Emergency lighting systems, the Centralized System and the Distributed System. In a Centralized System, the DC bulb in the Exit Signs and Remote Heads are powered from a Centralized Battery Unit. In a Distributed System, smaller battery units are scattered throughout the building, powering Exit Signs and Remote Heads in small sections of the building. Enough of these distributed units are used to make sure the entire building has proper coverage.

The system is also designed to illuminate the bulbs for a minimum predetermined time, depending on the building type. Most small low rise commercial buildings require a minimum of 30 minutes, while high rise buildings and institutions require 2 hours.

Regardless of the type, all Emergency Lighting Systems consist of a combination of 3 unique parts.

Power Unit:

The Power Unit contains a back-up power source (Battery) to illuminate the bulbs during a building power loss condition. The size of the battery packs varies depending on the number of bulbs it must illuminate and the minimum time it must operate.

Exit Signs:

Exit Signs are required at every exit, and any point in a corridor where a bend or obstruction prevents the sign at the exit from being seen. This means that if a hallway to an exit has several corners and bends, Exit Signs must be installed so that one can be seen from any point in the corridor. Basic rule is that from anywhere in a means of egress, there must be a visible Exit Sign. Exit signs that are not right at the exit use directional arrow to indicate the direction to the exit.

All Exit Signs (except self-luminescent ones) have two sets of bulbs inside them. On set (usually 2) are 100VAC bulbs for connection directly to the buildings power. The other (usually 1) is a DC bulb that connects to the Power Unit. When a power failure occurs, this bulb comes on to illuminate the sign.

Remote Heads:

Remote Heads are used to illuminate a route of egress. They are used in stairwells, hallways and other area's so that during a power failure there will be enough light to allow a person to evacuate safely. The bulbs in the heads are connected directly to the Power Unit so that they only illuminate during a power failure condition.
