SDC 1511SNAKV – Frequently Asked Questions

1) Will the SDC 1511S delayed egress maglock meet my local code, and which version do I order for NFPA 101 versus Chicago?
Mode is an order option on the 1511S, so pick it against the code the AHJ enforces. Four choices: BC for Chicago compliance with a fixed 15 second egress delay, BD for BOCA with a fixed 15 second delay, ND for NFPA 101 with a fixed 15 second delay, and NA for NFPA 101 with a selectable egress delay. If your jurisdiction lets you run 30 seconds with approval, NA is the one to take because the delay is selectable rather than locked at 15. Everything else about the lock is the same across the four.
2) What is the difference between the K and L reset options on the SDC 1511S ExitCheck lock?
K gives you the built-in keyswitch reset, a three position switch on the lock itself for reset, manual power up, and bypass. L is less reset, meaning the lock ships without that keyswitch and you reset it from somewhere else, typically a remote reset at a nurse station or security desk. If nobody is going to be standing at the door to clear an alarm, L plus a remote reset is the right build. If staff clear it at the opening, take K. Both are offered in all four finishes and all four code modes.
3) Do I need a separate delayed egress controller and sensor with the SDC 1511S, or is it all in the lock?
It's all in the one housing. The 1511S carries the ExitCheck electronics integrated into the magnet: visual countdown display, alternating verbal messages with countdown and alarm tone, built-in activation trigger, and an adjustable door movement sensor. That is the difference between this and a plain maglock, where you would be buying the mag, a separate delayed egress module, a horn, and a sensor, then wiring them together. Here you run power to the lock and set the field selectable options.
4) How much holding force does the SDC 1511S maglock have, and is that enough for a high traffic exit door?
1,650 lbs of holding force, which is the standard commercial single door rating and the number specifiers write for interior and perimeter openings in schools, hospitals, and retail. On a delayed egress opening the magnet is holding against push attempts during the countdown, not against a battering attack, and 1,650 lbs handles that. It is a single door lock, so a pair of doors needs one unit per leaf.
5) Can I use the SDC 1511S on a pair of double doors?
Not as a single unit. The 1511S is built for single door applications, so a pair takes two locks, one on each leaf. Order the same mode and finish for both so the countdown behavior matches, and note that the lock supports single or multi-door zone control and reset, which is how you tie the two leaves together so one activation alarms and resets as a zone rather than as two unrelated doors.
6) Will the SDC 1511S work with our wander management or infant abduction system?
Yes. The 1511S is compatible with wandering patient, patient and infant tracking systems, which is the usual reason it lands on a memory care or maternity unit door. The tag system drops power or triggers the lock, and the ExitCheck countdown and verbal message run at the door. The activation trigger is field selectable, so it can be set to respond to the tracking system input rather than only to push on the door.
7) Does the SDC 1511S run on 12 volts or 24 volts?
Both, with no jumper to move. The lock is auto-sensing dual voltage 12/24VDC, so it takes whatever your access control power supply is putting out and configures itself. That matters on a retrofit where you are tapping an existing panel and don't want to re-spec the supply. It also has voltage and current spike protection built in. It is not battery operated, so it needs a wired DC supply, and on a delayed egress opening that supply normally sits on backup power.
8) Does the SDC 1511S mortise into the frame or mount on the surface?
Surface mount. The lock and its armature attach to the face of the head frame and the top of the door with an interlocking quick mount assembly, so no frame is cut and no wire is pulled through the door leaf, only up to the header. That is what makes it a practical retrofit on an existing hollow metal or aluminum opening. The housing is aluminum.
9) After the alarm trips on a delayed egress maglock, does it relock by itself or does someone have to reset it?
Your call, set in the field. The 1511S has field selectable automatic or manual reset. Manual reset is what most codes expect on a secured opening, since it forces staff to come look at why the door was pushed; automatic reset suits a lower risk opening where you don't want a lock sitting released. With the K build the reset is the keyswitch at the door, and remote reset is supported either way for a central security desk.
10) Can I hold the SDC 1511S unlocked during business hours or a fire drill?
Yes, through the bypass. The integrated three-position keyswitch covers reset, manual power up, and bypass, and bypass is field selectable as sustained or timed. Sustained is what you use to keep a door free during visiting hours or a drill; timed drops back to secure on its own so nobody leaves the building unlocked overnight. The 1511S also announces field selectable security or safety messages, so the verbal message can be set to suit whether the door is protecting people or protecting stock.
11) Is a delayed egress maglock like the SDC 1511S the right choice, or should I use a delayed egress exit device?
Pick by the door and by what is already on it. The 1511S is a surface mounted magnetic lock with the delayed egress electronics built in, so it goes on the header and leaves the existing latching hardware alone, which is why it suits a retrofit or a door where you don't want to change the exit hardware. A delayed egress exit device replaces the panic bar itself and puts the release in the pushbar, which is the better answer on a door that already needs a new exit device or where the AHJ wants the delay initiated by the panic hardware. On a door with no panic hardware at all, the maglock is the simpler run.
12) What finishes does the SDC 1511S ExitCheck maglock come in?
Four: 625 bright chrome, 626 dull chrome, 628 dull aluminum, and 710 dark bronze. All four are available in every code mode and in both the K keyswitch and L less reset builds. On an aluminum storefront header 628 is the usual match, and 710 matches dark bronze anodized entrances. If you are standardizing a building, note the finish now, because the countdown display sits at eye level on the header and it will be seen.
