BLASI – Emergency opening button green
BLASI – Emergency opening button green is a dedicated push‑button installed on BLASI‑type automatic‑door and barrier systems to allow safe manual emergency release of the door. The button is colored green to indicate “open” or “release” in line with common safety and door‑control practice, and is typically mounted at standard height on the operator tube or wall so it is clearly visible and easy to reach. Behind the panel it connects via wired contacts (often 1×NO or 1×NO & 1×NC) to the BLASI emergency‑release circuit, so pressing the button immediately overrides the normal closing logic and opens or unlocks the door. BLASI lists this simply as “Emergency opening button green” in its spare‑parts sitemap, so technicians usually source a standard green emergency‑door‑release button with a suitable contact rating and mounting‑hole pattern.
Product Details
BLASI – Emergency opening button green forms part of the safety infrastructure around BLASI‑series swing, sliding and revolving‑door systems, allowing users or staff to open the door quickly in an emergency without using the automatic sensors. The large green dome or flat‑face button is designed for easy pressing, often with a high‑impact plastic or metal surround, and is frequently mounted in a protective box or cover labeled “Emergency Open” or “Push to Open.” When pressed, the internal contacts close (or open, depending on the BLASI design) to send a clear signal to the BLASI control board, which then forces the door to stop, open or remain open, overriding any normal closing or locking functions. This emergency‑release logic is usually wired into the BLASI emergency‑stop or safety‑circuit path so it is both fast‑acting and reliable.
The button is typically rated for auxiliary control‑circuit use (several amps at low voltage or 24 V DC, often with extra dry contacts for third‑party alarms or interlocks), and is intended for indoor or sheltered entrances where humidity and temperature are moderate. Many similar green emergency‑opening buttons available in the market are designed for over 1 million operations and are built with vandal‑resistant materials, which suits high‑traffic BLASI‑type entrances such as malls, airports and office lobbies. By using BLASI – Emergency opening button green, facility managers and safety engineers provide a clear, code‑respected way to manually open the automatic door in an emergency, while keeping the control‑logic wiring simple and consistent with BLASI‑area practice.
