ISL-28 TBTS SERIES D EMERGENCY LIGHTING EQUIPMENT

INSTRUCTION MANUAL IMPORTANT SAFEGUARDS When using electrical equipment, basic safety precautions should always be followed, including the following:

READ AND FOLLOW ALL SAFETY INSTRUCTIONS 1.

CAUTION – To prevent electrical shock, do not mate unit connector until installation is complete and A.C. power is supplied to the unit.

2.

CAUTION – This fixture provides more than one power supply output source. To reduce the risk of electrical shock, disconnect both normal and emergency sources by turning off the A.C. branch circuit and by disconnecting the unit connector.

3.

CAUTION – This is a sealed unit. The integral, high temperature Ni-Cad battery is not replaceable. Replace the entire unit when necessary and recycle or dispose of the nickel-cadmium battery properly.

4.

DO NOT USE OUTDOORS. The ISL-28 is for use with grounded, UL Listed, indoor fixtures except in heated air outlets or hazardous locations.

5.

The ISL-28 requires an unswitched A.C. power source of either 120 or 277 volts. Properly cap the unused A.C. lead.

6.

Do not mount near gas or electric heaters.

7.

The ISL-28 should be mounted in locations and at heights where it will not readily be subjected to tampering by unauthorized personnel.

8.

The ISL-28 will cold strike and operate for 90 minutes one 2′ to 4′ T5 or T8 linear lamp.

9.

The ISL-28 is compatible with all A.C. magnetic and electronic ballasts including multiple lamp ballasts with one lamp operating in the emergency mode.

10.

The use of accessory equipment not recommended by the manufacturer may cause an unsafe condition.

11.

Do not use this equipment for other than intended use.

12.

Install in accordance with the National Electrical Code and local regulations.

13.

Installation and servicing should be performed by qualified personnel.

14.

Lighting fixture manufacturers, electricians, and end-users need to ensure product system compatability before final installation.

SAVE THESE INSTRUCTIONS

THIS UNIT CONTAINS A RECHARGEABLE NICKELCADMIUM BATTERY. PLEASE RECYCLE OR DISPOSE OF PROPERLY.

INSTALLATION INSTRUCTIONS CAUTION: Before installing, make certain the A.C. power is off and the ISL-28 unit connector is disconnected.

1. LAMPS OPERATED

The ISL-28 can be used with most 2′-4′ lamps. Refer to the chart below for the type of lamp(s) operated and the number of lamps to be operated in emergency mode.

2. MOUNTING THE ISL-28

Remove the ballast channel cover. Mount the ISL-28 in the ballast channel at least 1/2″ away from the A.C. ballast(s).

When battery packs are remote mounted, the remote distance can not exceed 1/2 of the distance from ballast to lamp specified by the A.C. ballast manufacturer. For example, if the A.C. ballast manufacturer recommends no more than 25′ remote distance, then the battery pack should not exceed 121/2′. Under no circumstances should the battery pack exceed a distance of 50′ from the lamp.

3. WIRING Refer to the wiring diagrams on the back page for the appropriate wiring of lamp(s) and ballast. Install in accordance with the National Electrical Code and local regulations. For additional wiring diagrams consult Customer Service.

4. INSTALLING THE THREADED BODY TEST SWITCH (TBTS) Recessed Troffer Fixture – Select a convenient location with proper clearance in the ballast cover and drill or punch a 7/8″ hole (1/2″ knockout). Insert the 7/8″ bushing into the hole. Push the plastic tube through the bushing. Route the leads of the TBTS through the plastic tube. Connect the LED wires from the unit to the TBTS (Red/Black or Red w/tag to Red, White/Red to White). Push the entire assembly back into the tube until the lens collar rests against the plastic tube. The plastic tube should be adjusted so that the TBTS is within ¼″ of the fixture lens. The TBTS must be visible after installation. Refer to Illustration 1. Linear Fixture – Select a convenient location on the fixture so the TBTS can be seen after installation. Allow for proper clearance inside the fixture and drill or punch a 1/2″ hole. Remove the nut from the TBTS. Push the TBTS housing into the 1/2″ hole and secure with the nut. Connect the LED wires from the unit to the TBTS (Red/Black or Red w/tag to Red, White/Red to White). Refer to Illustration 2.

5. WIRING THE A.C. INPUT A. The ISL-28 and A.C. ballast must be on the same branch circuit. B. The ISL-28 requires an unswitched A.C. power source of either 120 or 277 volts. Select the proper voltage lead and cap the unused lead. C. When the ISL-28 is used with a switched fixture, the A.C. input to the ISL-28 must be connected ahead of the fixture switch. Refer to Illustration 3 for switched and unswitched fixture wiring diagrams.

6. LABELS Attach the appropriate labels adjacent to the TBTS. Annotate Re-lamping label for lamp type and wattage. The Caution and the Re-lamping labels must be on the fixture in a readily visible location to anyone attempting to service the fixture.

7. COMPLETING INSTALLATION When the installation is complete, switch the A.C. power on and join the ISL-28 unit connector.

OPERATION Normal Mode – A.C. power is present. The A.C. ballast operates the fluorescent lamp(s) as intended. The ISL-28 is in the standby charging mode. The TBTS will be lit providing a visual indication that the battery is being charged. Emergency Mode – The A.C. power fails. The ISL-28 senses the A.C. power failure and automatically switches to the Emergency Mode. One lamp is illuminated, at reduced output, for a minimum of 90 minutes. When the A.C. power is restored, the ISL-28 switches the system back to the Normal Mode and resumes battery charging. See page 1 of the Instruction Manual.

TESTING & MAINTENANCE Pressing the red lens on the TBTS turns off the light on the TBTS and forces the unit into emergency mode, interrupting power to the designated A.C. ballast. The emergency lamp is now being lit by the ISL-28 unit. After releasing the TBTS, the fixture returns to normal operation after a momentary delay. To simulate a “BLACK OUT” use the circuit breaker to turn off A.C. power. Initial Testing – Allow the unit to charge approximately 1 hour, then press the TBTS to conduct a short discharge test. Allow a 24 hour charge before conducting a one hour test. The ISL-28 is a maintenance free unit, however, periodic inspection and testing is required. NFPA 101, Life Safety Code, outlines the following schedule: Monthly – Insure that the TBTS is illuminated. Conduct a 30 second discharge test by depressing the TBTS. One lamp should operate at reduced output. Annually – Insure that the TBTS is illuminated. Conduct a full 11/2 hour discharge test. The unit should operate as intended for the duration of the test. “Written records of testing shall be kept by the owner for inspection by the authority having jurisdiction.”

SERVICING SHOULD BE PERFORMED BY QUALIFIED PERSONNEL. Consult Customer Service or visit www.iotaengineering.com for current warranty information. Page 3
