The PDM8-12V includes an integrated fire trip input that can be monitored using a 22K EOL resistor or set as non-monitored via voltage trip. Each of its eight outputs can be configured to either cut power or remain active during a fire trip using jumper switches.
A common fault relay output is available to signal failures in any circuit, which can be used to trigger DVR alarm inputs, security systems, building management systems, or local sounders/strobes to notify personnel of equipment failure.
Available in both 12VDC and 24VDC models, the PDM8 helps prevent total system shutdown by isolating faults in individual circuits. It incorporates advanced Surface Mount Technology and features eight individually fused M205 1A circuits, each equipped with an LED to indicate fuse status, along with a power status LED. Technicians can customize fuse ratings as needed, with 1A fuses provided by default.
The unit is designed for easy installation with 35mm DIN rail mounting hardware.
Installers must ensure that the total system current draw does not exceed the connected power supply and fire trip relay ratings (10A).
