Alpha WPT504-10BU 10 Wireless Pendants+Wristband
- Non-returnable or refundable

The WPT504-10BU from Alpha is a 10 Wireless Pendants+Wristband. The Alpha Communications® WPT504 Wristband Pendant features the great range and reliability of 900 MHz in a small, water-resistant package. Users can wear the pendant in the shower or bathtub, outside in the rain, or other environments where the pendant may be splashed with water, or momentarily submerged. The pendants have a single-button design with "press and one second hold" activation, making the pendant very easy to use, yet still reduces false alarms. When the WPT504 is activated, it vibrates briefly and its red LED blinks rapidly for five seconds, then blinks slowly until the alarm is cleared. Alarms may be cleared by placing the ACC500K Alarm Clearance Card over the button, or by a sequence of button presses. The WPT504 features a fully supervised RF link to ensure reliability. The built-in LED flashes with all transmissions, including supervision, so the user can see the transmitter is still functioning. The battery is a field-replaceable long-life 3V lithium type (model BA004), and is included.
