The SF503UL Neck Lanyard Pendant feature the great range
and reliability of 900 MHz in a small, waterproof package.
The pendants can be worn in the shower or bathtub, outside
in the rain, or other environments where they may be splashed
with water or momentarily submerged.
The pendants have a single-button design with “press and
one-second hold” activation, making them very easy to
use but very resistant to false alarms. When a pendant 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 an RP500 Alarm Clearance
Card over the button, or by a sequence of button presses.
The pendant transmitters are especially suited for assisted
living installations. They feature a fully supervised RF
link to ensure reliability. The built-in LED flashes with all
transmissions, including supervision, so the user can seethat the transmitter is still functioning.
