CPSC sets battery-backup safety tests for garage door openers from December 29
Our take
Battery-backup openers must keep their safety reversal working at low charge or stop running, under a rule due December 29. Plus the unattended-closing rules.

Key points
- A CPSC direct final rule published October 30, 2026 aligns the federal garage door opener standard with the 2025 edition of UL 325. It takes effect December 29 unless significant adverse comments arrive by November 30.
- Openers with battery backup must keep their entrapment protection working down to the opener's lowest operating voltage, or be rendered inoperative.
- If the battery cannot power a full open-and-close cycle, the CPSC says the door will remain open and the opener will not work until the battery is charged or mains power returns.
- Existing rules for unattended closing require an audible and visual alarm for at least 5 seconds before the door moves, and do not allow it on one-piece or swinging doors.
- Add-on control accessories may not override an opener's entrapment protection and must be marked with the openers they can be used with.
The U.S. Consumer Product Safety Commission (CPSC) has updated the mandatory federal safety standard for garage door openers, which the regulation calls automatic residential garage door operators, to cover models that run on batteries or have battery backup. The direct final rule, published in the Federal Register on October 30, 2026, takes effect on December 29, 2026, unless the CPSC receives a significant adverse comment by November 30. In that case, the agency says, it will publish a notice withdrawing the rule before that date.
The standard, 16 CFR part 1211, applies to openers made since January 1, 1993. It is built on the entrapment protection requirements of UL 325, a voluntary standard, and the update matches it to UL 325's seventh edition, dated September 15, 2025, whose garage door opener revisions the Commission accepted in October 2025. The Commission voted 3-0 to publish the rule.
What changes for battery-powered openers
Openers must already start reversing a closing door within 2 seconds of contact with an obstruction, apart from the first foot of door travel, which the rule exempts. The rule now states that its requirements also cover battery-powered openers, including those with backup batteries, whether or not the user can replace the battery. Such an opener must either keep its entrapment protection working on battery power or be rendered inoperative, meaning it will not complete a full open-and-close cycle. Compliance is tested with a fully charged battery and again with the same battery run down to the opener's lowest operating voltage.
The CPSC describes the practical effect: the opener checks that there is enough charge for both an opening and a closing cycle. If there is not, the door will remain open and the opener will not work until the battery is recharged or mains power is restored.
The rule also makes smaller changes, including these two. Openers must still check their secondary safety device, such as a photoelectric sensor, at least once on every close cycle, but the check now covers only whether the device is present, dropping “correct operation”, which the UL committee said there was no practical way to test. And the instruction requirements now refer to an operator “or system”.
Rules for closing the door when nobody is at the controls
Openers and separately sold control accessories that permit “unattended operation to close a garage door” must meet another set of requirements, in 16 CFR 1211.14, which this update leaves unchanged.
| Topic | What the rule requires |
|---|---|
| Door type | Not permitted on one-piece or swinging garage doors |
| Switching it on | One or more intentional actions; installing and setting up an accessory can count |
| Warning | An audible and a visual alarm for at least 5 seconds before the door moves: at least 45 dB measured 10 feet in front of the device, and a flashing light of at least 360 lumens or a 40-watt incandescent bulb |
| Canceling | Using a wall control, remote or keypad during the warning prevents the movement; during movement it stops the door |
| Obstructions | After an obstruction reverses the door, one more attempt is allowed; after two, unattended closing is suspended until someone uses a regular door control |
| Add-on accessories | May not interfere with, override or alter the opener's entrapment protection; must be marked for use only with UL 325-compliant openers made after a stated date, or with listed openers |
What to check
- Door type: unattended closing is not allowed on one-piece or swinging doors, and an accessory's package must warn that the feature is only for sectional doors, or that the device is not for one-piece or swinging doors.
- Compatibility: an accessory's packaging, the product itself and its instructions must say which openers it may be used with.
- Battery backup: from December 29, the federal standard requires these openers to keep their entrapment protection working on a low battery, or to stop operating.
