FIELD DEVICE Functional characteristics FD-DA02 is a module for the acquisition of sensors data and to command actuators devices like sirens, electrical locks, etc with the following characteristics: ♦ Data acquisition from dry contacts (ON/OFF) ♦ Data acquisition from supervised sensors managing 5 states per sensor (normal, alarm, tamper, cut circuit, short-circuit), and inject pseudo-random interference in order to prevent level detection from the outside. ♦ Able to control resistive and inductive loads up to 4 loads, from 0.3ADC (0.2 AAC) up to 2.5 ADC (1.8AAC) per channel adding optional relays) Output monitoring, with alarm generation in the event of faults Able to monitor a FD-PA01 power supply module through a suitable connection, for all the main electrical parameters including the battery effectiveness tests. Visual fault and/or alarm indication Connection to FD-BUS through an RJ45 connection Double RJ45 connector (internally in parallel) for easy reconnection to the FD-BUS. Galvanic separation of the FD-BUS backbone from the local reference ground Possibility of connecting the FD-BUS remote power supply to the local power supply through jumpers. The equipment is protected against the following events: ♦ polarity reversal on the cables (RJ45) connecting to the FD-BUS ♦ voltage surge in the power supply ♦ negative voltage peaks at outputs with inductive loads The FD-DA01 module is part of the Orangelink system and can perform the data acquisition functions related to the status of sensors and/or contacts, and control electrolocks and/or turnstiles. The module can operate in two different ♦ In dry contact (access control) acquisition mode, the module can acquire the status data from 8 contacts. ♦ In supervised contact acquisition mode (intrusion dtection and access control), the module can acquire the status data from 4 sensors, and manage the 5 possible states (normal, alarm, tamper, cut, short-circuit).
