SDC Spacesaver 2090 Series Right Angle Electric Mortise Bolt Lock with Fail-Secure Operation

Patented Concealed Mortise Locking Technology for Access Control Applications

The SDC Spacesaver 2090 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 24VDC fail-secure mortise bolt lock installs via simple mortise cutout in virtually any standard frame or door lock stile, with the entire lock concealed for complete aesthetic acceptability and enhanced security. Built with stainless steel bolts and specification grade solenoids for superior performance and longevity.

Professional Features & Benefits

  • Patented Right Angle Design: Spacesaver bolts project at right angles to the lock mechanism, allowing installation in virtually any standard frame or door lock stile through simple mortise cutout.
  • Concealed Installation: Entire lock mechanism remains hidden for complete aesthetic acceptability and enhanced security compared to surface-mounted alternatives.
  • Specification Grade Components: Stainless steel bolts and specification grade solenoids deliver superior performance in both force and longevity compared to commercial grade alternatives.
  • Fail-Secure Operation: 24VDC fail-secure configuration ensures door remains locked during power loss for maximum security applications.
  • Automatic Relock System: Field adjustable and bidirectional automatic relock ball switches keep bolt retracted while door is open, automatically projecting to lock upon door closure.
  • Tamper Resistant Construction: Freely rotating bolts make tampering or cutting attempts extremely difficult, enhancing overall security performance.
  • Field Selectable Dual Voltage: Built-in voltage flexibility with power regulator and voltage/current spike protection for reliable operation.
  • Fire Safety Certified: UL 10C Positive Pressure Fire Tests certified along with ULC-S104 and ULC-S533 compliance for egress door applications.

SDC 2090AHU – Frequently Asked Questions

1) Will the SDC 2090 Spacesaver mortise bolt stay locked if the building loses power?
Yes. The 2090 is a fail-secure lock, so the bolt stays projected and the door stays locked when the 24VDC drops. That makes it a security lock, not an egress-release lock. If your opening needs the door to release on power failure (a stair tower on a fire alarm interface, for example), a fail-secure bolt is the wrong choice and you want a fail-safe device instead.
2) Can an SDC 2090 electric bolt be mortised into a narrow aluminum door stile or does it need a wide stile?
The right angle bolt is the whole point of the Spacesaver design: the bolt projects at a right angle to the lock body, so the mechanism lies along the stile instead of needing depth behind the bolt. SDC states it installs by a simple mortise cutout in virtually any standard frame or door lock stile. That is what lets it go into openings where a conventional inline electric bolt will not fit.
3) What is the difference between the BPS and DPS options on the SDC 2090, and do I need both?
They monitor two different things. Bolt Position Status reports whether the bolt itself is projected or retracted. Door Position Switch reports whether the door leaf is closed. You can order the 2090 with neither, with either one alone, or with both together. If your access control head end only needs to know the opening is secured, BPS is the one that proves the bolt actually threw. DPS alone tells you the door is shut but not that it locked. Card access systems that alarm on forced or held-open doors usually want both.
4) Will the SDC 2090 bolt fire into the door edge and jam when someone closes the door?
No. The 2090 uses field adjustable, bidirectional automatic relock ball switches. The switch holds the bolt retracted while the door is open and projects it once the door closes, so the bolt cannot slam into the strike edge. Bidirectional means it works whichever way the door swings, which matters on a pair or where handing changed after the frame went in.
5) Is the SDC 2090 electric bolt approved for use on a fire rated door?
It is certified to UL 10C Positive Pressure Fire Tests and complies with ULC-S104 and ULC-S533, which is what lets it go on egress door applications on both sides of the border. Note it is fail-secure, so the fire alarm interface and any required release has to be handled by the rest of the opening's hardware, not by this bolt dropping out.
6) What power supply do I need to run an SDC 2090 mortise bolt?
Plan on a 24VDC supply. The 2090 is field selectable dual voltage with a built-in power regulator and voltage/current spike protection, so it tolerates the supply variation you see on a shared access control power run. Size the supply for the solenoid inrush along with whatever else is on the circuit.
7) Can you see the SDC 2090 lock once it is installed, or is it hidden in the door?
Fully concealed. The entire lock body sits inside the mortise cutout in the frame or stile, with nothing on the face of the door or the frame. For a lobby or a glass front entry where a surface mounted electromagnetic lock and its bracket would be an eyesore, that is the practical reason to spec a mortise bolt over a mag lock, and it also removes the exposed housing an attacker would go after first.
8) How well does the SDC 2090 bolt hold up against someone trying to cut or pry it?
The bolts are stainless steel and they rotate freely, so a hacksaw or reciprocating blade skates on the bolt instead of biting into it. SDC pairs those with specification grade solenoids rather than commercial grade, which is where the throwing force and cycle life come from on a door that gets worked hard all day.
9) Should I use an electric mortise bolt like the SDC 2090 or an electric strike on my access controlled door?
An electric strike releases a latch that some other lockset throws, so you still need a lock on the door and the strike has to match that latch. A mortise bolt like the 2090 is the locking device itself, mortised into the frame or stile, and it needs no lockset and no matching strike prep. Pick the bolt when the door has no mechanical lock to work with, when you want the hardware out of sight, or when a narrow stile leaves no room for strike prep. Pick a strike when the door already has a latching lockset you intend to keep.
10) Is the SDC 2090 rated for a hospital or school corridor, or is it a residential lock?
Commercial. SDC builds the 2090 for commercial access control duty with specification grade solenoids, and the applications it is written for are healthcare access control, educational institution safety systems, government and municipal buildings, industrial facilities and multi-tenant residential. On an institutional standardization program, the fail-secure bolt with BPS reporting is what gives the head end proof the opening is actually secured.
