    Full text manual (for reference)

    Instruction manual for the United Security Products STAND DOWN SD-1 Wheelchair Monitoring System — a self-contained, batteryless fall-prevention chair sensor pad.

    Overview

    STAND DOWN SD-1 is a completely self-contained wheelchair/seat monitoring system with no tangled wires, no control units, no hardware, and no batteries. The sensor pad measures 9" x 16" and is placed on the wheelchair seat, with the control unit routed through the seat opening. It is designed to detect when a patient attempts to rise from the seat and sound an alarm to prevent falls.

    Key Features

    • Complete one-piece system — no tangled wires, control boxes, or batteries to replace
    • Slip-resistant surface, "patient proof" tamper resistant design
    • Thin, patient-comfort design
    • Nurse Call Station output for integration with facility call systems
    • Alarm volume control
    • Latex free and environmentally friendly
    • Moisture proof — quick wipe down cleaning
    • Folds for easy storage
    • 1-year warranty from date of first use; may be stored up to 1 year before first use

    Setup & Operation

    1. System Placement: Locate the pad on the seat, allowing the control unit to slide between the seat and backrest. The STANDDOWN logo should be in the front/right corner of the wheelchair seat.
    2. Monitoring: With the patient seated, hold the control unit and move the slide selector from OFF (down position) to ON (center position). The system will not alarm while the patient remains seated; if the patient attempts to rise, the alarm will sound. When the patient sits back down, the system automatically resets with no alarm. Alarm volume is adjustable via the Alarm Volume Control.
    3. Pause Feature: If a patient is being escorted from the wheelchair for temporary non-wheelchair activity (e.g., toilet duties), move the slide selector to PAUSE. In this position the unit emits low-volume beeps as a reminder that the system is standing by (neither monitoring nor fully off). Move the selector back to ON once the patient is reseated to resume monitoring.
    4. Nurse Call Integration: If Nurse Call Station monitoring is desired, connect the accessory cable to the Nurse Call Output jack on the pad, with the other end going to the Nurse Call Station via a "Y" plug adapter accessory.
    5. End Monitoring Session: Move the slide selector to OFF (down position).
    6. Storage After Use: The system may be loosely rolled or folded through its length for storage. Follow the instructions on the bottom of the pad to avoid damage and voiding the warranty.

    Cleaning

    STANDDOWN is moisture proof and may be cleaned with standard healthcare disinfectants. Do not immerse in water.

    Testing & End of Life

    Caregivers should test the disposable STANDDOWN system before each use by applying pressure to the pad by hand, moving the slide switch to ON, and removing hand pressure. If STANDDOWN fails to alarm, immediate replacement is required.
