Dormakaba Saffire ELPS Emergency Power Override Assembly (118-515990)
The Dormakaba Saffire ELPS Emergency Power Override Assembly (Part No. 118-515990) is a battery-powered backup device designed to maintain access control functionality on Saffire LX series locks during a power outage or primary power failure. When building power is interrupted, this assembly allows authorized personnel to override the lock electronically — avoiding the need for mechanical key bypass and preserving audit-trail integrity at the door.
Designed for property managers, security integrators, and facilities teams who cannot afford a loss of access control during an emergency, the ELPS assembly connects via USB and draws power from four AAA batteries, providing a reliable, on-demand power source without requiring hardwired backup infrastructure at the door level.
Key Features
- Emergency power override capability for Saffire LX series access control locks
- USB connector interface — simple, tool-free connection at the lock
- Powered by 4x AAA batteries (included or field-supplied)
- Maintains electronic access during primary power loss
- Supports audit trail continuity — no need to revert to mechanical key override

- Part Number: 118-515990
- Brand: Dormakaba
Ideal For
- Multi-family and commercial property managers requiring code-compliant emergency egress

Dormakaba 118515990 – Frequently Asked Questions
1) Will the Dormakaba 118-515990 ELPS override work on any Saffire lock, or only certain models?
The 118-515990 ELPS Emergency Power Override Assembly is built for Dormakaba Saffire LX series locks. That is the compatibility Dormakaba states for it. If the openings in your building run a different Saffire family or another Dormakaba electronic lock line, this assembly is not the backup part for them.
2) How does the ELPS emergency power override connect to the lock, and do I need tools at the door?
Connection is a USB connector at the lock, so no tools and no disassembly of the lock case. You bring the assembly to the door, plug it in, and power the lock long enough to present a credential. Nothing is hardwired, so there is no conduit, transformer, or door-loop work required to have emergency power capability at an opening.
3) What powers the Dormakaba ELPS override assembly - does it need to be plugged into building power?
Four AAA batteries power it, which is the whole point of the device: it is self-contained and independent of building power. That is what lets it bring a Saffire LX lock back up when primary power at the door has failed.
4) Why use a battery override instead of just carrying the mechanical key when a Saffire LX lock loses power?
A mechanical key bypass opens the door but leaves no electronic record of the entry. Powering the lock back up with the ELPS assembly means the credential is read normally and the event lands in the audit trail like any other opening. For multi-family and commercial sites where who entered and when has to be defensible, that difference is the reason the assembly exists.
5) Is the Dormakaba 118-515990 something I mount at each door or a portable tool one person carries?
It is a portable, on-demand power source, not door-level infrastructure. Dormakaba describes it as supplying power without hardwired backup infrastructure at the door, and it connects by USB, so a single unit serves every Saffire LX opening on the property rather than needing one per door. Integrators and maintenance teams generally stock one or two per site in the truck or the shop.
6) How do I order the Dormakaba Saffire ELPS override - are there different versions or finishes to specify?
There is one configuration. Order part number 118-515990 from Dormakaba and there is nothing further to select: no handing, no finish, no size. The only decision left is whether you have AAA cells on hand, since the assembly runs on four of them.
7) Does the ELPS override unlock the door by itself, or does someone still need a valid credential?
It restores power to the lock, it does not release it. Dormakaba describes the assembly as letting authorized personnel override the lock electronically, meaning the Saffire LX comes back to life and reads credentials as it normally would. Access rules stay in force through the outage.
8) Is the red button on the Dormakaba ELPS assembly what triggers the power override?
The unit carries a red button alongside its connector ports. Plug the USB lead into the Saffire LX lock and the assembly delivers battery power to the lock so a credential can be presented; it is a hand-held override device, not a keypad or a credential in its own right.
