ASSA ABLOY AAIEMAGA4SSHSAL A4 600 lbs EM Lock, Single Door, Non-Monitored

Overview

What it is

The ASSA ABLOY AAIEMAGA4SSHSAL is the non-monitored A4 single-leaf electromagnetic lock (EM lock or maglock) from ASSA ABLOY, often called a 600 lbs magnet. It holds a door shut with 250 to 280 kg of force while powered and releases instantly when power is cut.

What it is used for

It is used on access-controlled single doors in offices, IT and server rooms, shops and apartments, including aluminium, glass, wooden and steel doors, swinging in or out, with the magnet surface mounted on the frame.

Key features

• Holding force 250 to 280 kg.
• Fail-safe: unlocks when power is removed.
• Dual voltage, selectable on site: 12 or 24 V DC (plus or minus 10%); 450 mA at 12 V or 225 mA at 24 V.
• Smart electronics remove residual magnetism for instant release; silent operation.
• Self-aligning armature plate that pivots to allow for door drop; aluminium case, 250 x 47 x 26 mm.

Buying considerations

This version has no lock status output. If the access system must know that the door is bonded and closed, order the monitored AAIEMAGA4SSHRAL (Hall-effect and reed switch). Being fail-safe, it needs a backed-up supply or a secondary lock where security must be kept during power cuts. Rated -10 to 55 °C, 0 to 90% humidity; CE approved and UL listed.

Compatibility and what you need

Add a 12 or 24 V DC access control power supply, an exit button and a controller or reader. For glass or outward-opening doors, ASSA ABLOY lists L, Z and L, U and I brackets for the A4 magnet.
