The new stopper station three-pack from STI offers three buttons with protective shields, three activation choices and three snap-in message choices per button. Easy-to-use, each button’s activation can be changed on site from Key-to-Reset, Turn-to-Reset or Momentary (default). To help protect the buttons against damage and accidental activation, three stopper station shields are included. Optional illumination (red, green, white) allows users to easily find the push buttons in a dark corridor. The multipurpose push button kits are available in blue, yellow or green. They are available from local distributors and are UL/cUL listed and ADA compliant.
