ZKTeco EX28-L Slim Stainless Steel Exit Button, 91 x 28 mm

Overview

The ZKTeco EX28-L is a slim push button for the inside of an access controlled door, 28 mm wide against the 86 mm of a square plate. That width is the whole point: it fits the narrow upright of a glass or aluminium door frame, where a square plate will not sit flat. It is stainless steel and tested to 500,000 presses.

Is it right for you?

• It suits a glass entrance, where the frame is often only 40 to 50 mm wide and a standard plate would overhang the glass.
• It works with any access panel, standalone terminal or direct lock wiring, because the output is a plain NO/COM dry contact.
• For a standard 86 type wall box, the square EX86-S is the usual choice.

Key features

• 91 x 28 x 22 mm, sized for a narrow frame or upright.
• Stainless steel panel for high-traffic and public areas.
• NO/COM dry contact output.
• Rated for 500,000 operations (aging test qualified).
• 12 V DC supply.
• Rated -20 to 55 °C and 0 to 95% relative humidity; 0.05 kg.

What else you need

Two-core cable to the exit input of the controller or to the lock circuit, and the 12 V DC access control supply. On a fire escape route, an emergency break glass unit alongside it.

Installation

An access control installer or electrician can fit it. The button wires into the exit or release input on the controller, or in a simple installation it breaks the lock power circuit directly. Surface mount it on the frame upright beside the door.

Before you buy

• Measure the frame upright: the button is 91 mm long and 28 mm wide.
• Pair with an emergency break glass unit on an escape route.
