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.

iO LED Lighting’s raye is designed for cove and wall slot applications. Two cross sectional profiles are available: 3"h x 3.6"w and 2"h x 6"w. raye is ideal for applications where spatial conditions are limited but functional light is required. This low voltage LED based luminaire offers three luminous intensities for a variety of architectural lighting requirements. raye’s optical assembly has been designed to uniformly illuminate the interior surfaces of the cove for a clean appearance, while offering a very precise asymmetric beam projection. raye is perfect for delivering light at low angles for hallow cove and wall slot conditions. Individual units may be placed end to end without socket shadows, offering a uniform distribution of light along an architectural reveal. Projected average rated life is 50,000 hours at 70% of lamp lumen output. raye is available with three lumen outputs for white light.

The MicroSet Passive Infrared Low Voltage Occupancy Sensing Ceiling Sensor is a motion sensing lighting control that is used for energy savings and convenience. The sensor is designed to detect motion from a heat-emitting source (such as a person entering a room) within its field-of-view and automatically switch lights ON. These sensors have multi-segmented lenses. For units to sense motion, the person must cross between two segments. PIR sensors are considered line-of sight sensors, meaning that the sensor must be able to have a direct line-of-sight to the person making the motion. The sensor includes self-adaptive technology that continuously self-adjusts sensitivity and Time Delay in real-time, maximizing the potential energy savings that are available in the particular application.
