SDC 101-KDENA 101-DE Delayed Egress Keypad Controller

The SDC 101-KDENA ExitCheck is a wall-mounted delayed egress controller designed for commercial doors requiring controlled exit and emergency release. Featuring selectable 15- or 30-second egress delays, a programmable digital keypad, and a reset and bypass keyswitch, it operates with compatible SDC delayed egress magnetic locks and exit devices. The controller supports 12/24 VDC automatic voltage selection, audible voice instructions, an alarm tone, and a digital countdown display. Its aluminum housing and NFPA 101 operation mode support delayed egress applications in commercial, institutional, and healthcare facilities.

SDC 101-KDENA ExitCheck Delayed Egress Controller with Keypad and Keyswitch, 12/24VDC

The SDC 101-KDENA ExitCheck Delayed Egress Controller provides centralized electronic control of delayed egress locking systems in healthcare facilities, retail stores, educational institutions, transportation facilities, and commercial buildings. Part of the Security Door Controls 101-DE Series, the controller manages compatible slave electromagnetic locks or electrified exit devices to prevent immediate unauthorized egress while maintaining code-required emergency release functionality. Its NFPA 101 operation mode provides a field-selectable 15- or 30-second exit delay, allowing security personnel to respond when an occupant attempts to leave through a secured exit. The integrated digital countdown display, audible alarm, and verbal instructions communicate the remaining delay time before door release. The 101-KDENA combines a three-function digital keypad with a mechanical reset and bypass keyswitch, providing authorized personnel with two methods of controlling the delayed egress system.

The 101-KDENA operates on automatically selected 12 VDC or 24 VDC input power, accepting a voltage tolerance of 10% and drawing a maximum of 180 mA at either operating voltage for the controller itself. The unit provides a 1-amp lock output and SPDT alarm and lock-status relay contacts, supporting integration with compatible locking hardware and remote monitoring equipment. The NA operating configuration allows installers to select a 15- or 30-second egress delay, a 1- or 2-second nuisance delay, and locked or unlocked operation after power restoration. During the nuisance delay, a warning tone sounds while the system monitors the activation input. If the triggering condition clears before the nuisance period expires, the controller resets without completing the unlock sequence. Once the nuisance period has elapsed, the irreversible release countdown continues until the programmed delay expires. A fire alarm or emergency release condition bypasses the normal delay to permit immediate egress through the compatible locking device.

The SDC 101-KDENA features an integrated three-function keypad that provides alarm and lock reset, adjustable 1- to 30-second timed bypass, and sustained bypass for authorized door operation. The additional keyswitch provides mechanical control of reset and bypass functions, while remote inputs support request-to-exit activation, access control integration, and external reset devices. The controller includes field-selectable male security voice instructions, female safety voice instructions, or alarm tones without verbal messages. Its digital display indicates armed status, nuisance activation, delayed release countdown, and unlocked conditions, providing visual feedback throughout the operating sequence. The system also supports anti-tailgate operation and configurable door-prop monitoring when used with appropriate door position equipment. These functions make the 101-KDENA suitable for patient wandering protection, infant security applications, retail loss prevention, and controlled commercial exit doors.

The SDC 101-KDENA is housed in an aluminum enclosure measuring 4-1/2 inches wide, 6-7/16 inches high, and 2 inches deep, with an approximate weight of 2 pounds. The controller supports recessed mounting using the included three-gang metal plaster ring or surface mounting with the separately available DEC-J three-gang enclosure. Compatible slave locking devices include selected SDC 1511DEV, 1571DEV, and 1581DEV electromagnetic locks, along with supported delayed egress exit devices. One controller can manage a single opening or a compatible pair of doors when the required slave locking hardware is installed. The 101-KDENA is supplied without the mortise key cylinder, which must be ordered separately. The 101-DE Series carries manufacturer-listed certifications including UL 294, UL 10B, UL 10C, and applicable ULC standards, with California State Fire Marshal approval. All installations require appropriate fire alarm integration, an approved power supply, compatible locking hardware, and approval from the local authority having jurisdiction. The SDC 101-KDENA provides selectable delayed egress control, audible and visual annunciation, and dual keypad/keyswitch operation for commercial life safety and access control systems.
