Door stop alarm vs door handle alarm

Updated: October 2026

You have seen two small sirens that both claim to watch a door. A door stop alarm sits on the floor as a wedge. A door handle alarm hangs on the lever and listens for movement. They share a noise and almost nothing else. This page is the mechanism. The eight wedges are on the [alarm door stop comparison](/hub/door-and-window-security/alarm-door-stop). Swing, gap, and cell checks are in the [buying guide](/hub/door-and-window-security/alarm-door-stop/sub/alarm-door-stop-buying-guide). Peter F. separated these types on 19 October 2026. Neither kind was lab-tested. A qualifying purchase can earn a commission at no extra cost to you.

Two devices that share a siren and nothing else

A door stop alarm here is a plastic wedge inside an inward-opening door. KERUI asks for at least 8–10 mm. Jognee states 10–25 mm. A handle alarm hangs on the lever, needs no gap, and does not jam the door. Defender's ultra-slim unit, B0DZ7763YH, and Defender's handle alarm, B01BNLDBCI, were removed because they hang on the handle. Anskyloe's hanger, B0GXF61CWR, was removed as well. Those details are so you can recognise the type. They are not rows in the wedge table, and the prices were not checked again. SanJie, B0CR3QMGXK, is a plug-in chime on a UK plug, a third device.

When the floor decides it

The floor kills a wedge and does not touch a handle alarm. With about 8–10 mm or more, and a door that opens into the room, a wedge can sit there. A Lomuna reviewer needed about 20 mm before that plate switched. One Airbnb stay had no gap, so the wedge was dead weight. A handle alarm ignores that crack. Corridor fire doors are on the hotel door stop alarm page.

What you lose with a handle alarm

You lose the hold. Someone who turns the handle is not blocked by the hanger. Reviews on the removed Defender handle alarm say a light touch sets it off and the siren is short. Sold Secure Gold on that bullet is not BS 3621, and it is not the Sold Secure SS312 rating West Yorkshire Police describe. A logo on a hanging siren does not transfer to these wedges. The room lock comes first.

Which pages to use next

Use the wedge table when the door opens inwards and the gap is real. The comparison holds eight amazon.co.uk rows, including TECKNET at 4.4 from 557 of its own ratings and two Mengshen packs that share one review pool. Do not add Defender, Anskyloe, or SanJie back because a search showed them beside a wedge. Buy a handle alarm as its own product when there is no gap, or the door opens outwards, and you only want a noise if the handle moves. Decibel bullets on both types are claims. If the cylinder is loose or the door is a fire door, stop buying gadgets.

Common questions

What is the difference between a door stop alarm and a door handle alarm?
A door stop alarm is a floor wedge for an inward-opening door. It can add a little friction and it sounds when the door presses it, if the gap is large enough. A door handle alarm hangs on the lever, needs no gap, and sounds when the handle moves. It does not hold the door. The wedges stayed in this comparison. Defender and Anskyloe hangers were removed. SanJie's plug-in chime is a third type.
Which works if there is no gap under the door?
The handle alarm. A wedge needs space under the door, about 8–10 mm on KERUI's line, 10–25 mm on Jognee's, and about 20 mm in one Lomuna review. No gap means the door shoves the wedge or never loads the plate. A hanger does not use that crack. You give up the chock. If the door has a handle and no floor clearance, the hanger is the mechanism that can still make a noise.
Does a handle alarm hold the door shut?
No. It only makes a noise when the handle moves or the sensor trips. It does not jam the door the way a wedge can, and even a wedge will not stop a determined push. Reviews on one removed Defender handle alarm describe a short siren and trips from a light touch. If the door must hold, you need the lock. police.uk's advice on that point is about lock standards, not either gadget.
Do handle alarms need a 9V as well?
Not as a type. The removed Defender listings named LR44 on the ultra-slim and AAA on the handle alarm, with cells included when those pages were taken out. Anskyloe asked for AAA cells that were not included. The wedges in the kept table usually need a 9V you buy yourself, except TECKNET's USB-C cell and Jognee's LR44 line. Read the battery line on the exact hanger.
Is Sold Secure Gold on a handle alarm the same as a lock standard?
No. One removed Defender listing claimed Sold Secure Gold on its bullet. That wording is not BS 3621, and it is not the Sold Secure SS312 rating West Yorkshire Police explain for euro cylinders. It does not apply to the eight wedges here. A mark on a siren stays on that siren. Your lock is a separate purchase. That Defender claim is not treated as checked stock today.
Which one is in this comparison table?
Only the floor wedges: Jognee, Mengshen's single and 3-pack, KERUI's single and 2-pack, Lomuna's 2-pack, Miangerrn, and TECKNET. Defender's two handle alarms, Anskyloe's hanger, and SanJie's plug-in chime were removed and are not scored there. Use this page to choose the mechanism, then the comparison to choose a wedge. A hanger is outside that table on purpose.
