Model SI-L-A
Small Inverter
240W, 350W, 500W, 1000W, 1500W, or 2000W
FEATURES
- No individual battery packs to replace means lower maintenance costs, quicker testing, and greatly reduced electronic waste - only batteries need
to be replaced, not entire battery packs with electronics.
- High effiency, pure sine-wave inverter delivers full output throughout 90 minute operation.
- Automatic diagnostics for connected loads through patented RLS. Every day testing alerts room occupants and custodians of problems
with tubes, ballasts. When room switch is turned off emergency lights stay on for 2.5 seconds to ensure compliance with NFPA 101 and
eliminate lengthy and costly monthly testing procedures, which, in some districts, requires fire marshal supervision.
The SI-L-A is housed in a custom, powder coated, metal panel engineered for strength, but still lightweight to reduce shipping charges and allow
easy, single person handling and installation. All individual parts weigh less than 50 lbs.
-
Innovative battery harness with disconnects makes installation and servicing safe and easy. No factory startup required.
Modular Design - All major components are field replaceable.
Provides line voltage to any load you specify, compatible with fluorescent, incandescent, LED, halogen, and CFL loads.
Designated emergency fixtures will operate at full brightness, eliminating tedious calculations and guesswork.
-
Visible LED indicators supervise input, output, and charging circuits (2 LED’s)
Self resetting protection for overload, reverse polarity, shorts, temperature-controlled fan and more.
Designed for 25 year trouble-free operation
Full 3 year warranty on electronic components
6 year pro-rata warranty on batteries
UL924 Listed
Emergency fixtures operate at full output (2800 lumen for F32T8) during power failure for 90 minutes

NORMAL OPERATION
-- The SI-L-A Transfer Control will feed Utility Power through RL1 (see
diagram). This will supply all emergency loads connected to the SIL-A.
-- Supervisory LED’s will indicate that utility feed, inverter, and charger
are all energized and operating properly.
-- Test switch is easily accessible without opening cover and may be
pressed to switch SI-L-A to emergency mode.
TRANSFER
- Upon power failure the SI-L-A will transfer from utility power
to inverter power through relays RL1 and RL2 (see diagram).
- These relays are electronically interlocked with a time delay,
which prevents arcing when transfering between two out
of phase power sources. This safety feature protects the
SI-L-A, loads, as well as expensive equipment on both
sides of the inverter.
EMERGENCY OPERATION
- The SI-L-A Transfer Control will feed pure sine wave Inverter
Power through RL2 (see above). This will supply all emergency
loads connected to the SI-L-A for up to 90 minutes.
- Optional RLS emergency lighting controls in each room allow
emergency fixtures to be controlled from regular wall
switches, occupancy sensors, or dimmers during normal operation,
but will automatically illuminate emergency fixtures at
full brightness during emergency operation.
