UDP-2SF-A Addressable remote start device

Remote start devices UDP-2SF-A and UDP-3SF-A are designed to provide an alarm signal to the device receiving and controlling security and fire control addressable "Vesta 01F" after activation of the drive element. Activation of the devices 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>UDP-2SF-A and UDP-3SF-A devices have an inbuilt short-circuit isolator (hereinafter referred to as SCI). When a short circuit occurs in the address line "SHA", the short-circuit isolator galvanically isolates the minus terminals (input and output) of the address line "SHA".
