ALK Alarm kit
ALK 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

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
decibels.
For Hardware Applications
The assembly includes both a 24VDC Input and External Inhibit
standard. The External Inhibit provides remote arming and
dis-arming.
The key switch uses a standard 1
1
/4" (32mm) mortise cylinder
with a straight cam (Schlage 20-001, B502-191 cam). 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.
The alarm can automaticaly re-arm with a 1

/2, 3 or 4
1
/2 minute
time delay upon request.
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 or when alarm needs to sound
from both the exit device and trim side of the door. 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 a 6" x 20" decal for application on door
“EMERGENCY EXIT ONLY. ALARM WILL SOUND.” RSS push bar
trim can be used instead of the door decal, specify RSS push bar
trim when ordering the device.
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.

1. Standard, 98 ALK
2. Cylinder Dogging, CD98 ALK
3. Special center case dogging, SD98 ALK (98/99 Series only)
4. If AR desired, specify AR 1.5, 3 or 4.5
