Now you can specify and install a UL924 Listed Emergency Power Control, RLY-SW-2, which converts up to 20A of normal light fixtures to approved emergency lights. During normal operation, the RLY-SW-2 dims designated emergency lights using the same controls as normal (non-emergency) lights. During a utility power interruption, the RLY-SW-2 turns designated emergency lights on, regardless of switch position. The RLY-SW-2 is intended for use with such switching controls as wall switches, occupancy sensors, relay panels, and ON/OFF room controllers. Which Model Do You Need? For Choose Model 0-10V, EcoSystem, or DALI Dimmable Loads RLY-DIM-2D Line Voltage Dimmable Loads RLY-DIM-D Patented Automatic Diagnostic When the room switch is turned off, RLY-SW-2 tests itself for 2.5 seconds, testing that an emergency power source is available and that the RLY-SW-2, ballast, and lamp(s) are functioning correctly. This feature eliminates the need for manual monthly testing and is approved for this purpose. This allows installation in any location because its test switch does not need to be accessible. This feature can be disabled in the field by cutting the blue jumper. Inverter or Fire Alarm Remote Test Switch Some applications demand that emergency lighting be activated upon fire alarm, security alarm, or remote test switch activation. The RLY-SW-2 is equipped with a low voltage override input (red jumper). Contact your local Myers Emergency Power Systems Sales Representative for more details. This device can be remotely tested by applying 24VDC to the red jumper wire. Applications include fire alarm override and inverter monthly testing. Please contact Myers Emergency Power Systems for application and wiring details. Mounting The RLY-SW-2 features a unique universal mounting, which is a single enclosure design that allows flush, fixture, plenum, or panel mounting, as shown below. Flush Mount Installation Junction Box Installation Fixture Mount Installation Recommended box size 4-11/16” with extension (total depth 4”minimum) Recommended box size 4-11/16” with extension (total depth 4”minimum). Tested to UL 2043: suitable for installation in the plenum. Confirm body size (2-7/8” x 1-3/4” x 17/32”) will fit in fixture ballast channel prior to installation.

Commerce Way Bethlehem PA 18017 610-868-3500 ǀ www.MyersEPS.com 3 Installation In order to install the RLY-SW-2 in accordance with national/local code requirements, a qualified electrician should review and understand the installation instructions: Check voltage and current requirements. Verify and lock out circuit breakers on both regular (utility) power and 24 hours emergency generator or inverter circuit. Install a self-adhesive 2" x 3" caution label in each fixture or load controlled by an RLY-SW-2 indicating that the load is supplied from 2 different power sources: normal and emergency. Review wiring diagram and connect wires, one at a time, in accordance with the numeric identification. In order to provide a safe light level, when regular power is interrupted, it is recommended that a minimum 5000 lumen are controlled by a 24 hour emergency circuit and are spaced no farther than 24' in any direction from each other in a normal 9' white ceiling environment. Initial Testing and Troubleshooting In a new installation, where hundreds of devices may be used, each having as many as 14 wires to be correctly connected, it is important that a fast, convenient method is used to check connections. In order to test that the wires are connected correctly, without any inconvenience to occupants, do not turn off regular (utility) power until you have checked each device as follows: 1. Check that regular branch circuit breaker is connected and utility power is available. The green LED should be lit. If the green LED is not lit, check connections and continuity to branch circuit breaker. 2. Check that the emergency branch circuit breaker is connected and emergency power is available. The red LED should be lit. If the red LED is not lit, check the connections and continuity to the branch circuit breaker. 3. Normal Operation Test: Turn the room switch or other control device to the “ON” position. Normal and emergency lights should turn on. Turn the room switch or control to the “OFF” position. Normal lights should turn off immediately. If the blue loop is connected, emergency lights should stay on for at least 2.5 seconds. If the blue jumper is cut and capped, emergency lights should turn off immediately. 4. Emergency Operation Test: Press and hold the test button. Emergency lights should illuminate at full brightness until the test button is released. Maintenance No maintenance is required to keep the RLY-SW-2 functional. However, regular testing should be performed when the lamps, ballasts, LED drivers, or arrays have been replaced or when remodeling has taken place. Single Line Drawings On a 20 Amp circuit, one RLY-SW-2 can control up to - 20 Amps of emergency lighting load, or twenty RLY SW-2s can each control one Amp of emergency lighting load. One RLY-SW-2 is required per switch leg or zone.
