Electrically locking
L9080 EL electrically locked (fail safe)
Outside trim is continuously locked electrically. The
latchbolt is retracted by a key outside or by the knob/lever
inside. Switch or power failure allows the outside knob/
lever to retract the latchbolt. The auxiliary latch deadlocks
the latchbolt when the door is closed. The inside knob/
lever is always free for immediate exit.
L9080 EU electrically unlocked (fail secure)
Outside trim is unlocked electrically. The latchbolt is
retracted by a key outside or by knob/lever inside. The
auxiliary latch deadlocks the latchbolt when the door is
closed. The inside knob/lever is always free for immediate
exit.
L9082 EL or EU Electrically locked or unlocked both
sides
The same as L9080EL/EU, except both knobs/levers are
locked or unlocked simultaneously. (Previously XL11-452).
Cylinders
All Schlage cylinders are available with the previously
mentioned locks. Specify the locks with the required
cylinder code, e.g. L9080PEL (code P) for classic and full
size Everest cylinders. For a complete list of order codes,
see "Ordering procedures" on page 134.
Replacement kit
L283-053 solenoid and driver, EL or EU.
Electrical requirements
Voltage
: 24V AC or 24V DC (max. 26V, min. 22V).
Peak current
: 1.3 Amps at 5 to 10 second intervals.
Holding current:
.135 Amps between peak current intervals.
Operating temperature
: max +151° F, min. -31° F.
RX Microswitch:
5 Amps, normally closed circuit.
Typical installation
All installations should be in accordance with local electrical
codes and National Electrical Code NFPA #70. It is
recommended that each lock have its own 24 volt
transformer. Two or more locks may be operated in
parallel from a single transformer provided it has the
necessary current rating. DO NOT connect locks in series
from a higher voltage rated transformer. Damage to locks
may occur if connected to a supply circuit that also
contains electromagnetic devices. The transient voltage
must be suppressed at the equipment producing it
before connecting the locks to a circuit. A varistor rate at
35 volts (at peak current) may be used for transient
voltage protection.
