Potter DRV-50 is a LED driver module. The DRV-50 communicates using an RS-485 (P-Link) connection to the panel providing 50 user-configurable LED outputs and 4 supervised dry contact inputs. The DRV-50 is connected to the fire alarm control panels using a four-wire RS-485 (P-Link) connection. This connection is
power limited and supervised. The 50 programmable LED outputs are located on connectors P1-P5, each containing 10 LED outputs and 2, 5VDC outputs.

The system LEDs and PZT control outputs are located on connector P6. The 4 programmable dry-contact inputs are located on connector P7. All input circuits are power limited and use a UL Listed 5.1k EOL resistor (Potter part #3005013). All outputs are power limited. The DRV-50 can be installed in the AE-2, AE-8, and AE-14 Accessory Enclosures. The DRV-50 can also be installed inside the PSN-1000E Intelligent Power Supply and larger control panel enclosures that include space for mounting stacker bracket modules.
