Did your New York store's automatic sliding doors get stuck half-open after a power outage? Do not try to force it open.

In the New York metropolitan area in late October, when stores were switching power, checking breakers or experiencing brief power outages, automatic sliding doors were sometimes stuck half-open, beeping repeatedly, or not opening and closing properly even after power was restored. This does not necessarily mean damage to the door itself. There may be a problem with the control unit, sensor area, backup power supply, lock or bypass setting, etc. However, if the entrance is a customer or employee passageway or an emergency evacuation route, ensuring that traffic remains smooth and predictable is more important than “sliding the door shut.” New York City fire codes require that essential escape routes be kept unobstructed at all times and associated door hardware and equipment must be in good operating condition. Which doors are required exits should be determined by the building manager and applicable regulations, taking into account site conditions.

First, we need to distinguish between “power outage” and “door failure.”

Site supervisors can observe three things without having direct contact with the facility: First, note whether there was a power outage throughout the store or just at that door, and whether there were any malfunctions in ambient lighting, checkout, or access control systems. Second, observe from a safe distance whether the door is fully open, half-open, or closed, whether there is debris, standing water, deformation of the edges of the entry mat, or whether a cart has entered the rail and sensor area. Third, record the door's initial reaction after power is restored (e.g., no display, persistent beep, opening but not closing, or no movement at all). Do not constantly cover sensors, push buttons, or pull open doors to get additional information.

Low-Risk Preparation

When should “manual bypass” no longer be allowed?

Some devices offer a manual mode for experienced users, but the unlocking, escape, and reset conditions vary depending on the door type. If you are not sure whether the door can be pushed manually, or how the locking, detection, and escape functions change when the door is pushed, this should not be considered a preliminary operating manual. In particular, the automatic bypass function should be stopped if the door drags, the guide rail generates friction noise, water accumulates at the bottom of the door, the glass becomes loose, or the operation is not smooth after power recovery. automatic sliding door The bottom guide of and sensor area error Our previous post on may help you understand this phenomenon, but it is no substitute for field inspection.

When requesting repairs, please include both “electrical” and “accessibility” information.

Before contacting your service provider, please have the exact location of the door (whether single or double door), location of the door before and after the outage, whether power has been restored, whether any alarms or annunciators are operational, whether current operations/closures are affected, and a work order and entry requirements for the building. If the door is used as an emergency exit, do not block, lock, or alter any part of the door to allow it to be reopened. Typical evacuation maintenance requirements are: New York City Fire Department fire regulations Please refer to . However, the specific scope of repairs, reopening conditions and applicable regulations will need to be determined based on site inspection and building requirements.
