From Locknetics Security Engineering, the 672 REX TouchBar non-latching exit bar needs only a 1/4 inch movement to release an electromagnetic lock or signal access control and alarm systems for a request to exit. In red, green or white push to exit letters, the TouchBar has an optional lighted version in which the letters are backlit in red but, when the bar is depressed, the letters change to green.
