OPERATION
184600

When AC power is applied, the LED test switch is illuminated, indicating that the batteries are being charged. When AC power fails, the 184600 automatically 
switches to emergency power, operating the lighting load at approximately 20% (Reprogrammed to 30%) of rated luminaire power (max. 180W (PST @ 2 
Vdc) or 120W (PST @ 3 Vdc) using 

Power Share Technology

. The 184600 can also be used as a stand alone 36W inverter when used with lighting loads 

less than or equal to 36 watts. During power failure, the LED test switch indicator will be off. When power is restored, the 184600 switches back to normal 
mode of operation and resumes battery charging. The minimum emergency operating time is 90 minutes. The charging time for a full discharge is 24 hours. 

184603

When AC power is applied, the LED test switch is illuminated, indicating that the batteries are being charged. When AC power fails, the 184603 automatically 
switches to emergency power, operating the lighting load at approximately 20% (Reprogrammed to 30%) of rated luminaire power (max. 110W (PST @ 2 
Vdc) or 80W (PST @ 3 Vdc) using 

Power Share Technology

. The 184603 can also be used as a stand alone 27W inverter when used with lighting loads 

less than or equal to 27 watts. During power failure, the LED test switch indicator will be off. When power is restored, the 184603 switches back to normal 
mode of operation and resumes battery charging. The minimum emergency operating time is 90 minutes. The charging time for a full discharge 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 test.

AUTO TEST
1. Initial Auto Test:

When the system is connected properly and powered on, the 184600/3 will perform an initial Auto Test. If any 

   abnormal conditions exist, the LTS will flash rapidly*. Once the abnormal condition is corrected, the LTS will function correctly.

2. Monthly Auto Test:

The 184600/3 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, and will test transfer function from normal to emergency, emergency 
   function, charging and discharging conditions. Monthly test time is approximately 30 seconds.

3. Annual Auto Test:

 It 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, Monthly and Annual Auto 
Test.

MANUAL TEST

1. Press the LTS 2 times continuously within 3 seconds to force a 30-second monthly test

.

After the test is complete, the 

next (30-day) monthly test will count from this date.
2. Press the LTS 3 times continuously within 3 seconds to force a 90-minute annual test. After the 

test is  complete

d

, the 

next 

(52-week)

 annual test will count from this date. 

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

.

LED TEST SWITCH (LTS) CONDITIONS 

POWER SHARE TECHNOLOGY
184600

The 184600 utilizes Power Share Technology (PST) which allows single or multiple 0-10 Vdc controlled luminaires (up to 180W combined normal luminaire 
power) to automatically adjust and share up to 36W of emergency AC power. During normal operation, the emergency inverter will pass through normal 
dimming voltage (0-10 Vdc) on the dim output leads, but then supply a default 2 VDC (or selectable **3 VDC) during emergency operation to achieve 
approximately 20% (or selectable **30%) of rated luminaire power during an emergency power failure.

** Reduced output mode 3 VDC (~30%) can be selected and easily programmed via the LED test switch (LTS) by depressing the illuminated button 
for 5 seconds, releasing, then repeating the 5-second button push (i.e. two 5-second extended button pushes within a 13 second timespan). LTS 
flash conditions confirming 3 VDC mode: Slow Blinking or ON. (Return to the default 2 VDC mode by repeating the extended button press 
sequence above).

Example (default 2 Vdc setting): Four 45W LED luminaires (180W) would share 9W each of the total 36W emergency power per 184600. 45W x 20% dim = 
9W * 4 luminaires = 36W. If the luminaire power is over 45W, then 3 or fewer luminaires can be operated. 
Example (3 Vdc setting): Three 40W LED luminaires (120W) will share 12W each of the maximum available 36W emergency power per 184600. 40W x 30% 
dim = 12W. Similarly, if each luminaire is 30W, then 4 units can 9W each; whereas if the luminaire power is over 40W, then 2 or less luminaires can be 
operated. When non-dimmable loads are used, the normal and emergency output will be 36W (max.) at temperatures of (10-50°C), 27W for (0-50°C) and 
27W for 2 hours (10-50°C). 

184603

The 184603 utilizes Power Share Technology (PST) which allows single or multiple 0-10 Vdc controlled luminaires (up to 110W combined normal luminaire 
power) to automatically adjust and share up to 27W of emergency AC power. During normal operation, the emergency inverter will pass through normal 
dimming voltage (0-10 Vdc) on the dim output leads, but then supply a default 2 VDC (or selectable **3 VDC) during emergency operation to achieve 
approximately 20% (or selectable **30%) of rated luminaire power during a power failure.

** Reduced output mode 3 VDC (~30%) can be selected and easily programmed via the LED test switch (LTS) by depressing the illuminated button 
for 5 seconds, releasing, then repeating the 5-second button push (i.e. two 5-second extended button pushes within a 13 second timespan). LTS 
flash conditions confirming 3 VDC mode: Slow Blinking or ON. (Return to the default 2 VDC mode by repeating the extended button press 
sequence above).

Example (default 2 Vdc setting): Two 50W LED luminaires (100W) would share 10W each of the total 20W emergency power per 184603. 50W x 20% dim=
10W * 2 luminaires = 20W. 
Example (3 Vdc setting): Two 40W LED luminaires (80W) will share 12W each. 40W x 30% = 12W, * 2 luminiaire = 24W total for the 184603.
