Watt Stopper /Legrand  has developed a new relay panel to provide fail-safe emergency lighting in a variety of commercial settings. The Emergency Relay Panel option is UL924 listed for use on emergency circuits. It is available as an option with Watt Stopper’s 24 or 48 relay size Lighting Integrator (LI) low voltage lighting control panels.
A dedicated normal power sense connection monitors the presence of normal power and allows the HDR relays to control the emergency lighting circuits based on ordinary control schedules and devices, such as switches, occupancy sensors, and daylighting control devices. When normal power is lost for any reason, all HDR relays controlling emergency circuits are each individually bypassed automatically by a set of normally closed contacts. The HDR relays do not change state during a power outage so lighting is restored when normal power is restored.
The Lighting Integrator emergency panel option is ideal for applications where always-hot emergency lighting circuits need to be controlled along with the normal lighting circuits. Because the lighting control panel with integrated yet dedicated emergency relays operates normally based on the type of intelligence card installed in the panel, this is suitable for virtually any type of application. These panels can be used reliably for fail-safe emergency lighting operation in schools, office buildings, libraries, airports, industrial plants, warehouses, and auditoriums.
