Addressable Manual Fire Alarm Pull Station IP 513-3SF-A for Fire Safety

Fire detectors manual addressable IP 513-2SF-A and IP 513-3SF-A (hereinafter - detector IP 513-2SF-A and IP 513-3SF-A, respectively) are designed to send a signal "Fire" to the device receiving and controlling alarm and fire control addressable "Vesta 01F" after activation of the driving element by the person who detected the fire. Detectors activation is performed in two actions: <ul> <li>- first action - displacement of the protective element (sealed transparent cover);</li> <li>the second action - activation of the drive element (button or lever, respectively).</li> </ul>The detectors ?? 513-2SF-A and ?? 513-3SF-A have a built-in short-circuit isolator (hereinafter - IKZ). In the event of a short circuit in the address line "SHA", IKZ performs galvanic isolation between the minus terminals (input and output) of the address line "SHA".
