Emergency Lighting Relay Switch

Normal emergency lights are fed via a normal emergency breaker panel and a wall switch or wallbox dimmer.

Emergency lighting relay switch.

A mix of exit style 24 7 and normally off emergency lights were used. The lighting load can be switched on off using an individual wall switch. The nlight npp16 er series relay pack is used to switch luminaires powered via an emergency circuit. This unit is intended for applications where both a normal and emergency branch circuit are to be connected to the emergency lighting.

With this method of emergency lighting selected branch circuits can be automatically switched from normal power to emergency power upon loss of normal power by a transfer switch that is electrically operated and mechanically held in accordance with 700 5. Our enclosed 20 amp electrically held ul 924 automatic load control relay is specifically designed for projects requiring control of an emergency lighting along with controlled general lighting in a space. A custom ul924 relay control system was requested by the specifier to replace a central dc battery system.

When normal power drops out the esr coil is deactivated and n c contact falls closed. The lighting on the emergency circuit is switched on and off based on the normal circuit switching input to the unit.

The shunt relay is used on designated emergency lights to shunt or bypass around the lighting controls when a normal power outage occurs.

These devices sense normal power and automatically connect the emergency power source to its lighting loads during a power outage. Emergency lighting transfer switches enable general illumination lighting fixtures to act as emergency lighting fixtures when an emergency power source is available. In automatic load control applications when normal power is present the esr relay coil is activated and the emergency panel is fed from normal power. Ideal for use along side a standard npp16 relay pack that controls a zone s normal powered lighting the npp16 er is designed to switch up to 16 amps of lighting load.
