SDC 1591U – Frequently Asked Questions

1) Will the SDC 1590 Series maglock work on a sliding door, or is it only for swing doors?
Sliding doors are what the 1590 Series is built for, and it also works on swinging doors, manual or automatic. The lock body mortises into the frame and the armature mounts on the door, so the two halves meet face to face as the door closes into position. That two-part arrangement is why it suits a slider, where a conventional surface maglock and armature bracket has nowhere to sit.
2) Does the SDC 1590 Series lock release on a power failure for emergency egress?
It is fail-safe, so cutting power releases the lock instantly and the door is free. That is the behavior life safety codes expect on an egress opening, and it means the maglock must be tied to the fire alarm and to whatever release devices the authority having jurisdiction requires. If you need the door to stay locked when power drops, an electromagnetic lock is the wrong device class entirely, use an electric strike or electrified lock specified fail-secure.
3) What is the Door Position Switch option on the SDC 1590, and do I need it?
The 1590 Series is ordered with or without a Door Position Switch (DPS), and that is the only choice on the order form. The DPS reports whether the door is physically closed back to your access control panel or alarm, which is what you want if the system has to log door-forced or door-held-open events, or supervise the opening. On a straightforward lock-and-release application with no monitoring, skip it. There is no field retrofit implied here, so decide before you order.
4) Is the SDC 1590 maglock rated for a fire door assembly?
UL 10B and UL 10C fire test certified, and UL 1034 burglary-resistant listed. It is also ANSI/BHMA Grade 1, the commercial durability tier for high-traffic openings. Those are the listings an institutional or MRO specifier usually has to show for a facility, so the 1590 Series clears a fire door assembly spec on paper.
5) Does the SDC 1590 electromagnetic lock need to be hardwired, or does it run on batteries?
Hardwired only. It is not battery operated, so the opening needs a DC supply at 12 or 24V run to the frame. Plan the power transfer and conduit into the header or jamb before the door goes in, because the lock body sits mortised in the frame and the wiring lands there.
6) Is the SDC 1590 Series a surface mount maglock or does it get cut into the frame?
Mortised. The steel lock case is let into the frame and the armature is mounted in the door, so almost nothing shows once it is installed. That means frame prep, which is a different job from a surface maglock that bolts to the header with an angle bracket. On a retrofit, confirm the frame has the depth and material to take a mortise pocket before committing.
7) Is the SDC 1590 maglock suitable for a residential slider, or is it commercial only?
Commercial. The 1590 Series is specified for commercial and institutional openings, hospitals, schools, retail, warehouse and government buildings, and it is built to Grade 1 for high frequency use. It needs a hardwired DC supply and fire alarm interface, which is why it belongs on a controlled commercial opening rather than a house.
