INSTALLATION and MOUNTING

IMPORTANT: Provide each unit with a single-phase AC un-switched power supply from a 120 V to 347 V circuit used for normal lighting. PRODUCT DAMAGE WILL OCCUR IF THE RATED INPUT VOLTAGE IS EXCEEDED.
WARNING: During installation of remotes, input wires from main unit to remote units must NOT be connected to each other or connected to ground. Failure to due so will lead to failure of the main unit.
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 DSL3 SP640L is 31.9 feet, the DSL3 SP1100L is 47.2 feet and the DSL3 SP2200L is 64.5 feet respectively, to meet the minimum illumination requirements of NFPA 101 (current Life Safety Code).
NOTE: Before installation, choose a location that allows adequate clearance for sliding the Rear Housing onto the Mounting Bracket (minimum 6-1/2″ above top edge of Bracket)
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).

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 RTKITHLP (remote tester accessory 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 RTKITHLP (remote tester accessory).

Cancelling emergency operation:

While in emergency Mode, press and hold the “TEST” button for several seconds or activate using the RTKITHLP (remote tester accessory), 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-learn clear 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 green 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 charged 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 RTKITHLP (remote tester accessory).

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:

Indication:	Status:
Off	Unit is off
Flashing green	Unit is in Emergency operation or Test
Solid amber	Battery is charging
Solid green	Battery is fully charged
Flashing R / G	Manual test, battery not fully charged (SDRT)
1x red flashing	Battery failure (SDRT)
2x red flashing	Lamp failure (SDRT)
3x red flashing	Charger / electronics failure (SDRT)
Flashing R/Amber	Unable to charge
Solid Red	Battery is disconnected

Remote Test (SDRT): (RTKITHLP 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.
