Von Duprin 75-ALK-711-48 75 Series Alarmed Kit, 48in, 711/US19 Flat Black Powder-Coated

Von Duprin 75-ALK-711-48 75 Series Alarmed Kit offers a robust solution for enhancing security in high-traffic areas. This 48-inch alarm kit is designed to deter unauthorized access while ensuring safe egress. When the touch bar is activated, an internal horn emits an 85-decibel alarm, signaling a potential breach. The alarm system is flexible, allowing for arming and disarming via a standard mortise cylinder key switch. This kit includes a 24VDC input and external inhibit standard, which supports remote arming and disarming. It operates on a single 9-volt alkaline battery, and a low battery alert ensures consistent performance. The auto reset feature is particularly useful, with preset times selectable at 1.5, 3, or 4.5 minutes, enabling seamless operation after a security event. Compatible with the 75 Series Exit Device, this alarm kit also comes with essential signage to inform users of the alarm's presence. Additional options include RX monitoring for the touchpad and optional LX monitoring for latch bolts. The ALK removes standard dogging but offers alternatives for those needing cylinder dogging. With its sleek flat black finish (US19), the Von Duprin 75-ALK-711-48 combines functionality and style, making it an ideal choice for both professionals and discerning homeowners.

75 Series Alarmed Kit, 48in, 711/US19 Flat Black Powder-Coated

Alarm kit (ALK) 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 decibels.

Features:

• 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, L583- 477 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.
• Auto reset (AR) option is available with this kit. This kit allows the device to resume the alarm option after a preset time. Preset times can be field selected at 1.5, 3, or 4.5 minutes.
• 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.
• 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 (SD) is available. Or, as an engineered special, the ALK can be moved to the hinge side of the device, and standard cylinder dogging (CD) can be added.
