The Conventional Zone Module FI700/M1CZ serves for the line-monitored connection of conventional detectors to a loop with Labor Strauss protocol. In this way manual call points and automatic detectors in conventional technology can be easily integrated into loopbased fire detection systems. The bi-directional communication on the loop allows for an accurate and fast evaluation of the status of the module and the conventional zone. For resetting special detectors, the module provides a dry relay output. The module can be either loopsupplied, or it can be connected to an external power supply. A capacitive termination of the conventional detection line ensures a low power consumption of the module and facilitates the detection of wire breakage. Alternatively, a resistive line termination can be set. A bi-colour status LED indicates the alarm condition in red colour, the fault condition in yellow and – optionally – the polling of the module in green. An integrated dual-isolator disconnects the loop in case of a short circuit. In this way, the undisturbed communication with the loop elements outside the faulty loop section is ensured. The module address can be set by means of the Programming Unit FI750/PU within the range 1 to 240.In addition, the programming unit allows for the readingout of several parameters, such as the default analogue value or the production date. Alternatively, the module can be addressed automatically if it is connected to a compatible fire detection control panel. The module is integrated in a plastic housing that is suitable for wall mounting.
