OPERATION

When AC power is applied, the LED test switch is illuminated, indicating that the batteries are being charged.

When AC power fails, the LVM-125/250 automatically switches to emergency power, operating the lighting load 

at rated emergency power. During power failure, the LED test switch will be off. When the AC power is restored, 

the LVM-125/250 switches the system back to normal mode of operation and resumes battery charging. The 

minimum emergency operation time is 90 minutes. A short term discharge test may be conducted after unit has 

been charging for 1 hour. The charging time for the full discharged battery of LVM-125 is 12 hours, of LVM-250 

is 24 hours. 

TESTING AND MAINTENANCE

The following Periodic testing is recommended to ensure the system is working correctly.

1. Visually inspect the LED test switch (LTS) monthly. It should be illuminated when AC power is applied.

2. Conduct a 30-second discharge test by switching off the emergency breaker every month. The LTS will be off.

3. Conduct a 90-minute discharge test once per year. The LTS will be off during the test.

AUTO TEST

This LVM-125/250 has an Auto Test feature which saves cost by reducing the need for manual testing.

1. Initial Auto Test

When the system is connected properly and powered on (make sure the load is switched on), the

LVM-125/250 will perform an Initial Auto Test. If any abnormal conditions exist, the LTS will blink quickly. Once

the abnormal condition is corrected, the LTS will function correctly. The Initial Auto Test will be restarted

automatically when the connected dimmable loads' maximum power increases.

2. Preprogrammed Scheduled Auto Test

a) The LVM-125/250 will conduct the first Monthly Auto Test after 24 hours and up to 7 days after initial power on.

Then monthly tests will be performed every 30 days.

b) Annual Auto test will occur every 52 weeks after initial power on.

- Monthly Auto Test

The Monthly Auto Test shall be executed every 30 days, and will test:

Normal to emergency transfer function, emergency, charging and discharging conditions are normal.

Monthly test time is approximately 60 seconds.

- Annual Auto Test

Annual Auto Test will occur every 52 weeks after the initial 24 hours full charge, and will test:

Proper initial battery voltage, 90-minute emergency operation and acceptable battery voltage at the end of the

full 90-minute test.

 If the Auto Test is interrupted by a power failure, a full 90-minute Auto Test will occur again 24 hours after the

 power is restored. If the power failure causes the battery to fully discharge, the product will restart the Initial

 Auto Test and Preprogrammed Scheduled Auto Test.

MANUAL TEST

1. Press the LTS one time to simulate emergency mode for 10 seconds.

2. Press the LTS 2 times continuously within 3 seconds to force a 60-second monthly test. After the test is

completed, the next (30-day) monthly test will count from this date.

3. Press the LTS 3 times continuously within 3 seconds to force a 90-minute annual test. After the test is

completed, the next (52-week) annual test will count from this date. Note: Prior to conducting annual test, the

LVM-125/250 must be charged for 24 hours.

4. In normal mode, press and hold the LTS for greater than 3 seconds to restart Initial Auto Test.

5. During any manual test, press and hold the LTS for greater than 3 seconds to terminate a manual test. The

Preprogrammed Scheduled Auto Test time will not change.
