It suits installers shutting down plant or controlling dampers from the loop. It is loop powered, has a single loop address and includes a short-circuit isolator.\u003c\/p\u003e\u003ch2\u003eKey features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFour outputs to control plant – 4 change-over relay outputs, each driven separately by the panel\u003c\/li\u003e\n\u003cli\u003eEither contact state to hand – N\/O and N\/C volt free contacts\u003c\/li\u003e\n\u003cli\u003eLocal fire and fault signals back to the panel – four inputs, fully monitored for open and short circuit\u003c\/li\u003e\n\u003cli\u003eNo separate power supply for the module – loop powered, with single loop address\u003c\/li\u003e\n\u003cli\u003eHelps limit a loop fault – integral short-circuit isolator\u003c\/li\u003e\n\u003cli\u003eStatus at a glance – green LED flashes when polled, amber LED when a short-circuit fault is detected\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFor installers\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePower: loop powered, 17 - 41 VDC.
