ASSA ABLOY AAIEMAGA4DSHSAL A4 Double Door EM Lock, Non-Monitored

Overview

What it is

The ASSA ABLOY AAIEMAGA4DSHSAL is the non-monitored A4 double-leaf electromagnetic lock (EM lock or maglock) from ASSA ABLOY. A single 500 mm housing carries two magnets, one for each leaf of a double door, with a combined holding force of 500 to 560 kg.

What it is used for

It secures double swing doors at office entrances, corridors, lobbies and access ways under access control, mounted on the head of the frame for inswing or outswing doors.

Key features

• Total holding force 500 to 560 kg across both leaves.
• Fail-safe: releases when power is removed; instant release with no residual magnetism.
• 12 or 24 V DC (plus or minus 10%), selectable on site; 900 mA at 12 V or 450 mA at 24 V.
• Self-aligning armature plates; silent operation.
• Aluminium case, 500 x 47 x 26 mm.

Buying considerations

Size the power supply for 900 mA at 12 V, roughly twice a single lock. This version gives no status signal; the monitored AAIEMAGA4DSHRAL adds Hall-effect bond sensing and a reed switch. Because it is fail-safe, plan a backed-up supply where doors must stay locked during outages. Rated -10 to 55 °C; CE approved and UL listed.

Compatibility and what you need

Add an access control power supply, exit button and reader or controller. The A4 bracket range (L, Z and L, U, I) covers outward-opening and glass doors.
