Fire alarm system translation Hello, everydody! Could you check my translation please. I've been trying to make it clear for English speakers. If you could improve this text to make it clearer I would really appreciate this. "To continue taking part in this (and in another major projects) we need all input/output modules to be adapted to work with Normally Closed (NC) contacts. Besides, it is necessary to have the line control (or maybe it’s better to say control on the line) at the very input of the module in a way that an open-circuit fault signals that there is malfunction while unlocking in the device shows that there is a fire."
