98/99™ ELectrical Options
Electric Latch Retraction — EL
The EL feature allows for the remote unlatching of exit devices. A control
station operator can flip a switch to retract the latch bolt and immediately
change an exit door to push-pull operation. A powerful, continuous duty
solenoid retracts the latch bolt, either for momentary unlatching, or for
extended periods of time. The EL feature is an alternative to manual dogging.
If manual hex-key dogging is required, specify HD-EL. If cylinder dogging is
required, the standard cylinder dogging is not available, but special center
case dogging is available, specify SD-EL. SD-EL is not available on the 9875
or 9975 devices.
EL devices are also useful with automatic door operators, and may be
applied to fire-rated applications when under the control of an automatic
fire alarm system.
UL approved for Class II circuit applications.
The EL option does not include the power transfer from door to frame, the
power supply, or the control operator. Refer to EPT-2 power transfer and
the PS873 power supply.
The PS873 with the 871-2 option card is minimum option card required.
Other option cards available for other functions, see PS873 power supply
for additional information.
Solenoid Specifications:
Continuous Duty –– 24 VDC
Current Inrush –– 16 Amps
Current Holding –– 0.3 Amps
To order, specify:
Standard –– Use prefix EL, example EL99L.
Hex Key dogging –– Use prefix HD-EL, example HD-EL99L
Special Center Case Dogging –– Use prefix SD-EL, example SD-EL99L
Popular EL Application
Signal Switch — SS
Monitors pushpad and latch bolt
The SS feature is used to signal the unauthorized use of an opening.
This device is equipped with two internal SPDT switches. One switch
monitors both the pushpad and the latch bolt assembly, making the
latch bolt tamper resistant, for positive security. An additional SPDT
switch is connected to the 1
¹ ₄" (32mm) mortise with straight cam for
alarm “bypass.” (Schlage cam reference B502-191). The device can be
connected to a security console, or may be used as a single door
alarm when used with a horn and power supply. A continuous current
electric transfer must be used for transferring power from the frame
to the door.
Pushpad reads:
“EMERGENCY EXIT ONLY – PUSH TO OPEN AND SOUND ALARM.”
Pushpad is only available in US32D finish with red silk-screened
lettering.
The SS mortise lock device is furnished with both the signal switch
device and the SS7500 mortise lock. The SS7500 mortise lock has
the versatility and advantages of the 7500 lock with the addition of
signalling functions to monitor latch bolt operation and the trim
locking function. The SS7500 mortise lock is supplied standard with
the SS mortise lock device.
To Order, Specify:
1. Prefix SS, example SS99L.
2. Handing Required, LHR or RHR.
Electrical Ratings :
Up to 2.0 AMPS @ 24VDC
