SDC Spacesaver 1490 Series Narrow Stile Right Angle Electric Mortise Bolt Lock with Field Selectable Fail-Safe Operation

Patented Concealed Mortise Electric Locking Solution

The SDC Spacesaver 1490 Series represents a fundamental innovation in electric locking technology, featuring a patented right angle bolt design that projects at right angles to the lock mechanism. This narrow stile mortise bolt lock is specifically designed to fit in 1-1/2"; frame or door stiles with 12/24VDC operation and field selectable fail-safe/fail-secure functionality. The concealed mortise installation allows placement in virtually any standard frame through a simple mortise cutout, providing complete aesthetic acceptability with enhanced security.

Professional Features & Benefits

  • Narrow Stile Compatibility: Designed specifically for 1-1/2"; frame or door stiles, enabling installation in space-constrained applications where standard locks cannot fit.
  • Patented Right Angle Design: Spacesaver bolts project at right angles to the lock mechanism, allowing concealed installation in virtually any standard frame through simple mortise cutout.
  • Dual Voltage Operation: Field selectable 12/24VDC power supply compatibility provides flexibility for various access control system requirements.
  • Field Selectable Fail Mode: Configurable fail-safe or fail-secure operation allows adaptation to specific security and life safety requirements.
  • Specification Grade Components: Stainless steel bolt construction with specification grade solenoids deliver superior performance in both force and longevity compared to commercial grade alternatives.
  • Automatic Relock System: Field adjustable and bidirectional automatic relock ball switches keep the bolt retracted while door is open, with automatic projection upon door closure.
  • Tamper Resistant Construction: Freely rotating bolts make tampering or cutting attempts extremely difficult, enhancing overall security performance.
  • Fire Safety Certified: UL 10C Positive Pressure Fire Tests certification ensures compliance with fire door assembly requirements.

SDC 1490AIQ – Frequently Asked Questions

1) Will the SDC 1490 Spacesaver electric bolt fit a 1-1/2 inch narrow stile aluminum door?
That's exactly the opening it was built for. The 1490 Series mortises into 1-1/2 inch frame or door stiles, which is where a conventional electric mortise lock body simply won't go. The patented Spacesaver design gets it there: the bolt projects at a right angle to the lock mechanism, so the body sits in the narrow stile and the bolt still throws where it needs to. Face plate is 8 x 1-1/4 x 1/8 inches, so plan the mortise cutout around that.
2) Is the SDC 1490 fail-safe or fail-secure, and can I change it in the field?
Both, and you set it on site. Fail mode on the 1490 mortise bolt is field selectable, so one part number covers an egress door that has to release on power loss and a storage or IT room that has to stay locked when power drops. Decide it during install rather than at the order desk.
3) Can I use an SDC 1490 mortise bolt on a fire rated door?
The 1490 Spacesaver carries UL 10C Positive Pressure fire test certification, with ULC compliance stated as well. That is the test that governs use in a fire door assembly. Set the fail mode to suit the life safety requirement for that opening, since the 1490 lets you pick either in the field.
4) How do I monitor whether the door is actually locked with an SDC 1490?
Two separate monitoring options, ordered as options on the lock. Bolt Position Status (BPS) tells the panel whether the bolt is actually thrown, and a Door Position Switch (DPS) tells it whether the leaf is closed. They're independent yes/no choices, so you can take one, both, or neither. If your head end needs to distinguish a door that's shut but unlocked from one that's secured, take BPS; if you only need door open/closed, DPS on its own is enough.
5) Does the SDC 1490 bolt stay retracted while the door is open, or will it hit the frame?
It stays retracted. Bidirectional automatic relock ball switches hold the bolt in while the door is open and project it as soon as the door closes, so the bolt never strikes the frame edge on swing. The switches are field adjustable, which is what you use to tune the projection point on a door that isn't hanging perfectly.
6) Should I use a concealed electric mortise bolt or a surface mounted electromagnetic lock on a narrow stile glass door?
Depends on whether the hardware can show. A mag lock sits on the frame face and header where everyone sees it; the 1490 mortises into the stile through a simple cutout and disappears, which is why it gets specified on storefront and lobby openings where appearance is part of the job. Security-wise the 1490 uses a stainless steel bolt that rotates freely, so cutting or wrenching it is difficult, and specification grade solenoids drive it. Where you cannot cut the stile at all, or the door has no usable 1-1/2 inch stile, a surface device is the fallback.
7) What finishes does the SDC 1490 Spacesaver mortise bolt come in to match the rest of my hardware?
Eleven finishes, in standard BHMA numbers: 335 dull black, 605 bright brass, 606 dull brass, 611 bright bronze, 612 dull bronze, 613 oil rubbed bronze, 625 bright chrome, 626 dull chrome, 628 dull aluminum, 629 bright stainless, and 630 satin stainless steel. On aluminum storefront, 628 and 630 are the usual matches to existing pulls and rails; 626 is the common match on commercial interior lever hardware.
8) Is the SDC 1490 rated for commercial traffic, or is it a residential lock?
Commercial only. The 1490 is built with specification grade solenoids rather than commercial grade ones, which SDC calls out for force and longevity, and a stainless steel bolt. It's the lock that goes on school and healthcare secure areas, stockrooms, government buildings, and multi-tenant residential common doors, all tied into an access control system rather than run standalone.
