R20D-EM Distributed UL924 Relay

The ILC Remote 20 Amp, Emergency Bypass Relay combines normal relay operation with a UL 924 bypass relay in one convenient package. Relays are available in both a wired (R20D-EM) and wireless (WR20D-EM) version that uses the 915MHz radio frequency for communication to ILC wireless devices. 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 and WR20D-EM have 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.
