INSTALLATION and WIRING

IMPORTANT: Provide each unit with a single-phase AC un-switched power supply from a circuit used for normal lighting. Operating voltage.
NOTE: The battery must be connected to the charger board prior to applying AC power to the unit. Battery damage may occur if the battery is connected longer than 24 hours without continuous AC power provided. See also “Important Battery Information”.
NOTE: The maximum mounting height of ELM2LF from ground is 11.1 feet, to meet the minimum illumination requirements of NFPA 101 (current Life Safety Code).
NOTE: Do not connect battery or power unit until remote units (if applicable) are fully connected and wires are isolated from other potentials (i.e. remote wires shall be isolated from earth ground).

JUNCTION BOX MOUNTING

1. On the mounting plate, remove the round center knockout and the desired pair of keyhole junction box knockouts.
2. Route leads through the center opening and use code-approved connectors to make the connections. Dress wires and connectors inside junction box. Units with Remote Lamp Wires: Connections to remotes wires should also occur in the junction box. If no remote lamps are connected, remote lamp leads (+ and – low voltage DC) should be left capped and dressed in mounting plate as shown.
3. Taking care not to pinch wires or connectors dressed inside junction box, secure mounting plate to junction box screws.
   NOTE: To ensure proper engagement of the mounting plate latches to the housing, DO NOT OVER-TIGHTEN THE SCREWS.

CONDUIT SURFACE MOUNTING
NOTE: to avoid interference with components in the housing, use the most compact wire connectors appropriate to the wire gauge.

1. At upper center of the mounting plate, remove the conduit connection knockout. Also remove at least three keyhole knockouts. Attach conduit and secure mounting plate to wall surface using fasteners with a minimum pullout rating of 30 lbs. each.

2. Make code-approved wire connections to the AC power supply, and remote lamps (if applicable). Dress wires into slots so that the connectors are secured as shown in Figure 2 or Figure 3.

3. Remove U-shaped knockout from top center of housing.
   Hint: Use a pair of wire cutters first to start a cut in the thick portion at each side of the knockout, then finish breaking it out with pliers.
   FINAL ASSEMBLY

4. Connect the polarized battery plug to the charger board. Make certain that the battery cable is routed to avoid interference with the AC input connector or other components.

5. Housing attachment to mounting plate: Make certain all wires and connectors are routed to avoid interference with other components.

TESTING and MAINTENANCE

NOTE: Emergency lighting systems should be tested in accordance with NFPA 101 or as often as local codes require, to ascertain that all components are operational.
NOTE: Allow batteries to charge for 24 hours before initial testing.

Manual testing:
If the batteries are sufficiently charged, either press and release the “TEST” button or use the RTKIT (remote tester accessory, up to 40’ away for SDRT units only) on the bottom of the unit to activate a 60-second test, during which the lamps will turn on. Triggering either option a second time will enable a 90-minute tests indicated by 5 flashes of the lamps. Triggering either option a third time will disable manual testing.

Self-Diagnostics (SDRT feature)
Units with this option automatically perform a 5-minute self-diagnostic test of the charging electronics, battery, and lamps every 30 days, and a 90-minute test every year, indicating system status as shown in the table at right. First self test occurs after 15 days of continuous AC Power.

Postponing a self-test:
If an automatic self-test occurs at a time when it is not desirable for the unit lamps to be on, it can be postponed for 8 hours either by pressing and releasing the “TEST” button or by using RTKIT (remote tester accessory, up to 40’ away).

Cancelling emergency operation:
Press and hold the “TEST” button for several seconds or deactivate using the RTKIT (remote tester accessory, up to 40’ away), during which the status indicator will flash until the lamps turn off. This restores the AC Reset state in which the unit is shipped.

Load-Learning feature:
Self-Diagnostic units automatically ‘learn’ their total connected lamp load during the first scheduled self-test (~15 days). The load-learning process can be initiated manually and should be initiated whenever the total connected lamp load of the unit is changed, or potentially troubleshooting a lamp error (unit indicates a lamp error yet all lamps are operating correctly) or a lamp is replaced. To clear the current load-learn, press and hold the “TEST” button for 7 seconds (count flashes), during this period the lamps will turn on. After 7 seconds, release the button, the lamps will turn off within 2 seconds indicating load clear is complete. If lamps stay on longer, the load clear was not successful and the process should be repeated. A new load learn will automatically take place at the next discharge from a fully charge state (solid green status indicator).

Clearing a failure indication:
After a failure condition has been corrected and power is restored to the unit, clear the failure indication either by pressing the “TEST” button once or by using the RTKIT
(remote tester accessory, up to 40’ away).

IMPORTANT BATTERY INFORMATION:
Batteries are perishable items. For best results, it is recommended that the batteries receive an initial charge within the first twelve months of the manufacture date of the fixture. In many cases, batteries beyond the initial charge recommendation time frame will recover if fully charged soon after installation. If such a battery does not recover after a full initial charge, it should be replaced. The manufacture date can be found on the outside of the unit packaging and on the product label as part of the Date Code / Series. The first two digits in the date code represent the year and the second two digits represent the month.

Unit Status Indications
The “TEST” button illuminates to indicate the following conditions:

Remote Test (SDRT): (RTKIT sold separately)
Units with the self-diagnostics/remote test feature allows manual test activation using a laser pointer. Aim the laser beam straight onto the circular area labeled near the “TEST” button for a few moments to activate a 60-second test. (See also “Manual testing”) A test in progress may be cancelled by aiming the beam at the test area again. NOTE: The remote tester should not be used to initiate the Load Learning feature.

BATTERY REPLACEMENT

Unit features and battery details shown may vary. See also “Battery Connection”,.

1. Disconnect battery from charger board. Release battery strap.
2. Replace battery, secure the strap snugly, and reconnect to the charger board.
