Heads
The lamp housing is constructed
of flame-resistant and impact-
resistant injection molded
thermoplastic with matching
finish. The three dimensional
swivel assembly permits
approximate aiming adjustment
from 80° vertical and 358°
rotation. The placement is
secured with a lockable pivot
mounted on a rotating base ring.
Lamps
Designed specifically for
emergency lighting applications,
the PAR 36 sealed beam type
design insures optimum glare-
free trapezoidal light distribution
along with horizontal and
vertical adjustment by rotating
the lens within the housing.
Housing
The rugged 18-gauge die-
formed steel housing is finished
with white corrosion-resistant
polyester powder coat paint.
Cabinet has keyhole mounting
slots and knockouts in top, rear
and side for AC/DC wiring
connections. Front cover has
large viewport to allow visual
inspection of electrolyte level
and removable cover provides
easy access to filler caps on
the battery(s).
Line-Latched
Sure-Lites’ line-latched
electronic circuitry makes
installation easy and
economical. A labor efficient
AC-activated load switch
prevents the lamps from
turning on during installation
to a non-energized AC circuit.
Line-latching eliminates the
need for a contractor’s return
to a job site to connect the
batteries when the building’s
main power is permanently
turned on.
Solid-State Charger
Supplied with a 120/277 VAC,
voltage regulated solid-state
charger. Immediately upon
restoration of AC current after
a power failure, the charger
provides a high charge rate.
The charge circuit reacts to
the condition of the battery
and alters the rate of charge in
order to maintain peak battery
capacity and maximize battery
life. Solid-state construction
recharges the battery following
a power failure in accordance
with UL 924.
Overload and Short
Circuit Protection
The solid-state overload
monitoring device in the DC
circuit disconnects the lamp
load from the battery should
excessive wattage demands
be made and automatically
resets when the overload or
short circuit is removed. This
overload current protective
feature eliminates the need
for fuses or circuit breakers
for the DC load.
Brownout Circuit
The brownout circuit in Sure-
Lites’ units monitors the flow
of AC current to the unit and
activates the emergency
lighting system when a
predetermined reduction
of AC power occurs. This
dip in voltage will cause most
ballasted fixtures to extinguish
causing loss of normal lighting
even though a total power
failure has not occurred.
Solid-State Transfer
The unit incorporates a solid-
state switching transistor which
eliminates corroded and pitted
contacts or mechanical failures
associated with relays. The
switching circuit is designed to
detect a loss of AC voltage and
automatically energizes the
lamps. Upon restoration of
the AC power, the emergency
lamps will switch off and the
charger will automatically
recharge the battery.
Low-Voltage Disconnect
When the battery’s terminal
voltage falls below 80% of the
rated voltage, the low-voltage
circuitry disconnects the
lighting load. The disconnect
remains in effect until normal
utility power is restored,
preventing deep battery
discharge.
Test Switch/Power Indicator
Light
Conveniently located Test
Switch allows for manual
verification of proper
operation of the transfer
circuit and emergency lamps.
The Power Indicator Light
provides visual assurance that
the AC power is on.
Serviceable Nickel
Cadm i u m B a t t e r y
The wet cell pocket plate nickel
cadmium battery remains the
premier battery for emergency
lighting applications. Designed
with an extra large electrolyte
reservoir, these batteries
require maintenance every
three to five years under
normal ambient conditions.
More frequent maintenance is
required when operated at an
elevated temperature. The
sintered plate design should
provide up to twenty-five
years of service if properly
maintained.
Warranty
All Sure-Lites’ units are backed
by a firm one-year warranty
against defect in material and
workmanship (excluding
lamps). Serviceable, long-life,
nickel cadmium batteries carry
a fifteen-year pro-rata warranty.
