OVERVIEW
The Power Sentry® constant power emergency drivers are technologically the most advanced,
intelligent, and versatile class 2 emergency drivers available to the industry today. These drivers
combine high quality and system reliability required for optimal compliance to NFPA 101 (Life Safety
code) and deliver constant light output throughout the 90 minutes of code-required emergency
operation in the event of a normal AC power loss. These emergency drivers are suitable for damp or
wet location, when installed in sealed and gasketed luminaires.
Class 2 emergency drivers are compatible with any LED array that operates at a voltage of 10V to
55V. This includes most Strips, Linear, Commercial Lay-ins, and Downlighting luminaires from any
luminaire manufacturer.
The new constant power series incorporates the industry-preferred Power Sentry Double Isolation
safeguard technology ensuring that no single fixture component failure or combination of abnormal
operating conditions, including feedback, can compromise the functionality of the emergency driver.
These drivers provide integrated self-diagnostics as a standard feature. Constant power emergency
drivers are UL listed for universal field installation. All the constant power products comply with the
CA Title 20 energy efficiency code and current NFPA 101 Life Safety code.

Notes:
1. At 77°F Ambient temperature, charge/discharge cycles and prolonged full discharge may reduce useful life.
2. All life safety equipment, including emergency lighting for path of egress must be tested in accordance with
all National Fire Protection Association (NFPA) and local codes. Failure to perform the required testing could
jeopardize the safety of occupants and will void all warranties.
3. Ambient temperature range where unit will provide capacity for 90 minutes. Higher and lower temperatures
affect life and capacity.

HOW TO ESTIMATE DELIVERED LUMENS IN EMERGENCY MODE
Use the formula below to estimate the delivered lumens
in emergency mode
Delivered Lumens = 1.25 x P x LPW
P = Ouput power of emergency driver. P = 10W for PS1055CP
LPW = Lumen per watt rating of the luminaire. This information is available
on the ABL luminaire spec sheet.
The LPW rating is also available at Designlight Consortium.
