Electrical Ratings:
Up to 2.0 AMPS @ 24VDC
Popular SS Application
Unauthorized use of this opening will activate the local horn. The key switch permits inhibiting this system for authorized entry.
ALK Alarm Kit
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. The horn is rated at 85 decibels.
For Hardware Applications
The assembly includes both a 24VDC Input and External Inhibit. The External Inhibit provides remote arming and dis-arming.
The key switch uses a standard 114 32mm mortice cylinder with a straight cam (20-001 w. 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 be re-armed with a 1 1/2, 3 or 4 1/2 second time delay.
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.
The ALK is available in two styles, 3327ALK, grooved cover and 3527ALK, smooth cover.
The ALK includes a decal for application on door “EMERGENCY EXIT ONLY. ALARM WILL SOUND”
SS push bar trim can be used instead of the door decal, specify SS push bar trim.
Standard - 3327ALK
EL Electric Latch Retraction
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 centre case dogging is available, specify SD-EL.
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.
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 PS0EL power supply.

PN Pneumatic Controlled Exit Devices
The PN feature provides remote latch bolt retraction in hazardous (ATEX rated) areas where electrically operated devices would not be permitted. The pneumatic solenoid will retract the latch bolt for momentary or prolonged periods. PN exit devices are particularly suited for use with automatic door operators.
The PN feature includes a special actuating linkage that gives building owners the option of mechanically or pneumatically dogging the exit device. If manual hex-key dogging is required, specify HD-PN (dogging the device, whether mechanically or pneumatically, makes the device function as a push/pull unit and reduces the wear on its moving parts.) If cylinder dogging is required, the standard cylinder dogging is not available, but special centre case dogging is available, specify SD-PN.
When activated pneumatically, the latch bolt(s) retract in 0.5 to 1.5 seconds. Devices operate best @ 80psi
This product will function only when it is part of a pneumatic system (air compressor, air lines, pneumatic controller etc.). Contact Relcross for full system specificaton.
