LightLEEDer Remote 20 Dimming Relay with Emergency Bypass

Model: R20D-EM

The ILC Remote 20 Amp, Emergency Bypass Relay combines normal relay operation with a UL 924 bypass relay in one convenient package. When normal power is lost the EM relay will automatically force ON the  EM load and send dimming to 100%. When normal power is restored the device will return to normal control. The R20D-EM has a relay test  button, and a wired input that can be used for a remote test switch or as an override connection from a Fire Alarm system.
