Potter HUSD-15B Series Owner's manual

  • Hello! I have reviewed the datasheet for the Potter HUSD-15BL and HUSD-15BM Hold-up Switches. These devices offer dual-button activation to prevent accidental alarms, have a tamper-protected design and come with a status window. The datasheet outlines the features, dimensions, and wiring details. I am ready to answer your questions about these hold-up switches.
  • What is the purpose of the dual button activation?
    What type of contact does the switch have?
    How is the switch protected from tampering?
    What is the difference between the HUSD-15BL and HUSD-15BM models?

The HUSD-15B Series is a Form C (SPDT), dual button hold-up switch that is designed to generate an alarm condition only when both buttons
are pressed simultaneously, thus preventing accidental triggering.
The housing of this series is specially designed with a status window, red (alarm) and blue (armed), to verify the switch condition. The housing
mounting screw is concealed to provide additional tampering protection. The built-in UL approved microswitch design generates an alarm
condition when the cover is removed or damaged. The terminal strip consists of three wire ports that provide a rm and secure wiring installation.
The HUSD-15BL is designed for latching operation when triggered. The HUSD-15BM is designed for momentary operation.
