General The TR-75 (red) and TR-75B (black) are intelligent addressable fire alarm control panels (FACP). TR-75 has a single line circuit (SLC) loop for connecting addressable detectors, which can support 75 System Sensor ® IDP/SK sensors and 75 IDP/SK modules or 75 Hochiki® SD devices per loop. For IDP or SK devices the overall point capacity to a maximum of 150 points per panel, or for SD devices the overall point capacity to a maximum of 75 points per panel. TR-75 has the interconnection capability for up to 32 panels. The system has two modes of operation, multiple panels covering one larger building, or multiple independent buildings. To network panels together use the SK-NIC network interface card. Copper wire or fiber optic cable panel connectivity can be used within the same networked system. TR-75 has a built-in dual-line digital and IP communicator with an optional cellular communication module, Form C trouble relay, and two programmable Form C relays. IFP-75 has powerful features such as detector sensitivity, day/night thresholds, drift compensation, pre-trouble maintenance alert, and calibration trouble alert. The TR-75 supports a variety of devices, including RA-2000, RA-1000 or RA-100 remote annunciator, 5824 serial/parallel printer interface module (for printing system reports), RPS-1000 power module, and IDP, SK, SWIFT wireless or SD devices..
