TBUD-150

2 loops microprocessor expansion card (500 addresses). 250 addresses per loop (detectors, modules, sounders and manual call points). To be used in CAD-150-8 and CAD-150-8-PLUS.

The TBUD-150 expansion card allows to add 2 loops to the 8 loop Detnov's addressable control panel: CAD-150-8 and CAD-150-8-PLUS; and its printer versions: CAD-150-8-P and CAD-150-8-PLUS-P. Each loop can control up to 250 addresses, with no limitations on the number of detectors and modules to install. The communication between the loop devices and the fire control panel is carried out through 2 wires. The connection of these devices in the loop supports non-polarity in case of not having ingtegrated isulator.
