PRODUCT OVERVIEW The Exit Sign Warehouse ESW-EML is ideal for wet locations, resistant to corrosive atmoshperes, non-hazardous dust environments, and to water spray, splashing water, or hose down locations. The adjustable halogen lamps are enclosed in a fully gasketed, corrosive resistant fiberglass enclosure designed to withstand the harshest environment. The solid-state charging circuit features short circuit and overload protection for years of reliable use. Wet location listed, resistant to corrosive atmoshperes, non-hazardous dust environments, and to water spray, splashing water, or hose down locations
SPECIFICATIONS Fully gasketed enclosure Fully adjustable 5 watt halogen lamp heads Optional G2 self-test/self diagnostics available Automatic brownout protection Contractor friendly, snap-together design AC lockout feature reduces installation time Wall or ceiling mounted UL 94-5VA flame rating 120/277V dual primary 60Hz input Low voltage disconnect 1 year warranty ETL Listed (conforms to UL924) 90 minute emergency run time Sealed momentary test switch Maintenance-free sealed lead-acid battery
CONSTRUCTION
Enclosure is constructed of precision molded fiberglass,
resistant to corrosive atmospheres. Fully gasketed clear
polycarbonate cover encloses lamps and reflectors, and offers
protection against wet, non-hazardous dust, and hose down
locations.
ILLUMINATION
Units come standard with two fully adjustable MR-16, 6 volt,
5 watt halogen lamps.
ELECTRONICS
Dual voltage, 120 volt or 277 volt input. Circuit provides
automatic brownout, short circuit, and overload protection. A
sealed momentary test switch and LED charge indicator are
included.
G2 SELF-TEST/SELF-DIAGNOSTICS
The circuit continuously monitors the operating condition
of the AC power, battery supply voltage, emergency lamp
continuity, and charging circuit.
If failure occurs, visual status will occur immediately via the
multi-colored LED’s. LED indicator(s) will illuminate until
fault has been corrected.
The G2 also monitors the transfer circuit as well as performing
automatic code compliant testing. The self-test will operate
the equipment in emergency mode five minutes every 28
days. Also, a 90 minute full-function test is performed every six months.
BATTERY
Maintenance-free, sealed lead-calcium battery provides an
estimated service life of 10 years with an operating temperature
range of 19oC to 30oC (65oF to 85oF).
EMERGENCY OPERATION
120/277 VAC dual voltage input with surge protected, solidstate
charging circuitry provides for a reliable charging system.
The charging system is furnished with low voltage disconnect,
AC lockout, brownout protection, AC indicator lamp and
test switch. The low voltage disconnect (LVD) feature will
disconnect the battery prior to an unacceptable deep discharge,
but not before the required 90 minute emergency operation.
The AC lockout feature prevents battery drain prior to the
initial energizing of utility power, and allows the installer
to complete all wiring and electrical connections without
energizing the emergency circuit. The brownout protection
circuitry will automatically switch the unit into the emergency
mode if the utility voltage sags below 20% of nominal.
Battery charging circuitry is entirely solid-state, and utilizes
a constant current charger for sealed lead-calcium battery
units. Battery recharge time after full discharge is less than
the required UL 924 standard. Line sensitive electronics cause
an instantaneous transfer to battery power if utility power is
lost, or a brownout condition is detected. When line voltage
is present and stabilized, the transfer circuitry switches back
to normal operation and begins recharging the battery. The
transfer circuitry can be tested via a momentary test switch
located on the housing.
CODE COMPLIANCE
The LL50H-N4 Series meets or exceeds all performance
standards as required by UL 924, NFPA 70, NFPA 101, NEC
and OSHA.
