98/99™ Electrical Options
Alarm Kit – ALK
The ALK battery alarm kit is a simple yet effective way to deter
unauthorized use of an opening. While the exit device is still a means of
egress, the ALK kit contains an internal horn. When the touch bar is
depressed, the horn sounds to provide an audible means of signaling
that the opening has been violated. The alarm kit can be armed
or disarmed by key. Thus allowing the exit device to be set in an armed
or disarmed mode. The horn is rated at 85 decibel.
The key switch uses a standard 1 ¹₄" (32mm) mortise
cylinder with a straight cam (Schlage Cam reference B502-191).
The unit operates on one standard 9-volt alkaline battery. When the
battery is weak, the horn will emit an intermittent low battery alert signal.
Also can be powered using the PS9 Power Supply. See PS9 for
additional information.
Alarm kits are available with a choice of two switch kits, RX or LX. RX
monitors the touchpad and is furnished standard. LX optional latch bolt
monitoring is recommended for use with surface vertical rod exit
devices. Specify ALK-LX.
Note: For latch bolt monitoring on a 98/9975 with ALK,
specify a SS7500 lock. LX switch not available for 98/9975 devices.
The ALK is available in two styles, 33A/99ALK, grooved cover and
35A/98ALK, smooth cover.
The ALK includes “EMERGENCY EXIT ONLY. ALARM WILL SOUND”
decal for application on door, or the SS push bar trim can be used
instead of the door decal,specify SS push bar trim.
The ALK is available with 2 optional circuit boards. External Inhibit (EI)
allows for the use of external switch to be used to arm, disarm and reset
the alarm. Auto Reset (AR) rearms the alarm after a preset time. AR is
available in three factory set times – 1
¹₂, 3 or 6 minutes.
To Order, Specify:
1. External Inhibit – ALK-EI
2. Auto Reset – ALK-AR3
When the ALK is used, standard dogging is removed. If cylinder dogging
is required there are two choices. Special center case dogging is available
or for 3’ or 4’ doors the ALK can be moved to the hinge side of the device
and standard cylinder dogging can be added.
To Order, Specify:
1. Standard, 98NL ALK
2. Cylinder Dogging, CD98NL ALK
3. Special Center Case Dogging, SD98NL ALK

Request to Exit — RX
The RX (Request to Exit) feature is used to signal the use of an opening.
This device is equipped with one internal SPDT switch which
monitors the pushpad.
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.
The RX switch option should not be used to control a load, but as a
signalling switch (0.5 amps. resisitive maximum).
The RX switch is available in a low current (LC) switch. Most commonly
used in computer operated monitoring systems.
To Order, Specify:
• Standard – Use prefix RX, example RX99EO
• Low Current – Use prefix RX-LC, example RX-LC98EO
Double Request to Exit — RX2
The RX2 feature uses 2 RX switches. Also available with the Low Current
(LC) switch.
To Order, Specify:
• Standard – Use prefix RX2, example RX299EO
• Low Current – Use prefix RX2-LC, example RX2-LC98EO
Latch Bolt Monitoring — LX
The LX feature is used to signal the use of an opening. This device is
equipped with one internal SPDT switch which monitors the latch bolt.
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.
The LX switch option should not be used to control a load, but as a
signalling switch (0.5 amps. resistive maximum).
The LX switch is available in a low current (LC) switch. Most commonly
used in computer operated monitoring systems.
To Order, Specify:
• Standard – Use prefix LX, example LX99EO
• Low Current – Use prefix LX-LC, example LX-LC98EO
Electrical Rating for all Switches:
• Standard – up to 0.5 Amp @ 24VDC Maximum
• Low Current (LC) - up to .05 Amp @ 24VDC Maximum
Note: All Switches can be either factory or field installed
