  • Additional Product Details

    Exit Alarm - Retrofit Kit

    Use with 99 Series Exit Hardware Only.

    The ALK Alarm Kit is a simple yet effective way to deter unauthorised use of an opening. When the touch bar is depressed, a horn signals that the opening has been violated. The alarm kit can be armed or disarmed by a key, allowing the exit device to be set in an armed or disarmed mode. The horn is rated at 85 decibels.

    • The assembly includes both a 24VDC Input and External Inhibit as standard. The External Inhibit provides remote arming and disarming
    • The key switch uses a Schlage 20-001.114.C.626 | Mortice Cylinder (20-001) w. L583-477 Straight Cam, which is included with the kit.
    • 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 (but not supplied) with this kit. This kit allows the device to resume the alarm option after a pre-set time. Pre-set times can be field-selected at 1.5, 3, or 4.5 minutes
    • Alarm kits are available with 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 an alarm needs to sound from both the exit device and trim side of the door. Specify ALK-LX


    The ALK includes a decal for application on the door 'EMERGENCY EXIT ONLY. ALARM WILL SOUND'

    This range of architectural-grade escape devices includes the 98 Series with its smooth mechanism case and the established 99 Series with its familiar grooved design. The two styles are mechanically and dimensionally identical and provide a solution for standard stile applications down to 89mm. They are best suited to heavy-duty situations on perimeter and internal doors where architectural-grade safe egress in panic emergencies is required.
