Setup & Installation

The LPX7 exit sign is designed for universal mounting, allowing for ceiling, wall, or end mount installations. Follow these steps for proper setup:

1. Site Selection

Choose a mounting location that is visible and meets local building codes for emergency exit signage. Ensure the mounting surface is structurally sound to support the unit's weight.

2. Power Disconnection

Before starting any electrical work, turn off power to the circuit at the main breaker panel to prevent electric shock.

3. Mounting Preparation

Determine the desired mounting method (ceiling, wall, or end mount). The unit is designed for semi-flush mount installation. Refer to the dimensions diagram for precise measurements.

4. Electrical Connection

Connect the unit to a 120 VAC or 277 VAC, 60 Hz power source. The LPX7 features dual voltage input. Ensure proper wiring according to the provided wiring diagram (typically found inside the unit or on a separate sheet). All connections must be secure and insulated.

5. Battery Connection

Connect the internal Nickel Cadmium (NiCAD) battery. The battery is typically pre-installed but may require connecting a small plug to the circuit board. Ensure the connection is firm.

6. Legend Configuration

Insert the desired red or green legend panels into the unit. The LPX7 ships with both options, allowing for field configuration.

7. Final Assembly

Secure the unit to the mounting surface using the provided hardware. Ensure the housing is properly closed and secured.

8. Power Restoration & Testing

Restore power to the circuit. The exit sign should illuminate. Press the "TEST" button (usually a small push-button on the side or bottom of the unit) to verify emergency operation. The unit should switch to battery power and remain illuminated for at least 30 seconds. Release the button, and the unit should return to AC power.

Operation

The Sure-Lites LPX7 Emergency Exit Light operates automatically. When connected to a continuous AC power source, the LED lamps will remain illuminated, indicating the exit path. The internal Nickel Cadmium battery continuously charges while AC power is present.

Emergency Mode

In the event of a power outage or interruption to the AC supply, the unit will automatically switch to emergency mode, drawing power from its internal battery. The LED lamps will remain illuminated for a minimum of 90 minutes, providing essential egress lighting.

Test Button

A test button is provided on the unit for routine maintenance checks. Pressing and holding this button simulates a power failure, allowing you to verify that the battery and lamps are functioning correctly in emergency mode. Release the button to return to normal AC operation.

Maintenance

Regular maintenance ensures the continued reliable operation of your emergency exit light. Always disconnect power before performing any maintenance.

Monthly Testing

Perform a monthly 30-second test by pressing the test button. The unit should operate on battery power for the duration of the test. If the lamps do not illuminate or dim significantly, the battery may need replacement or further charging.

Annual Testing

Conduct an annual 90-minute discharge test. Disconnect AC power to the unit and allow it to operate on battery power for 90 minutes. The lamps should remain illuminated for the entire duration. If the unit fails to operate for 90 minutes, the battery requires replacement.

Cleaning

Clean the exterior of the unit periodically with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these can damage the polycarbonate housing.

Battery Replacement

The Nickel Cadmium battery has a typical lifespan of 5-7 years. If the unit fails to meet the required emergency run time during testing, replace the battery with an approved Sure-Lites replacement battery. Ensure proper polarity when connecting the new battery.
