The Automatic Load Control Relay (ALCR) is a UL924 listed emergency device that tracks the state of normal power and
automatically bypasses control of the load to the emergency state
upon loss of the normal power sense feed source. The ALCR is
powered from an always-available normal/emergency source fed by
an upstream emergency transfer switch.
The DIN rail mount model also supports control bypass for 0-10V
luminaires, driving them to full output.
Automatically activates lighting loads upon loss of normal power sense feed source
Provides remote activation by dry contact closure for connection to a fire alarm or building management system
Configurable “return-to-normal” delay of 0-15 minutes
Support for control bypass of connected 0-10V controlled luminaires (ALCR-DIN only)
Maintenance-free
Application:
Any lighting control system requiring UL924 emergency bypass of individual circuits
