Safety Technology International REX PLUS ED-50 User Manual - page 2
Like father, like son. Introducing the next generation of Rex, the famous barking dog alarm. In addition to
the sound of a ferocious, attack dog, Rex Plus offers the sounds of the rainforest. Choose the sound that
suits you best. Try the continual sounds of the rainforest, or the option that allows you to use these same
sounds as an annunciator. Another option includes an angry, barking dog followed by the sound of a siren
for 20 seconds. Rex Plus is versatile and provides an excellent way to deter burglars, without the annoying
problems of owning a real dog. With his electronic radar eyes, Rex Plus can “see” through doors, walls and
glass. And once his cord is plugged into any standard 110 VAC electrical outlet, he will stay on duty around
the clock, indefinitely.

Operation Instruction
1. Insert the adaptor plug into the unit, then plug AC adapter into outlet.
2. Choose the feature you wish by adjusting the switch on the back of the unit.
a. Rainforest (sound is continuous).
b. Watchdog - Detects moving objects. When Rex “sees” movement, barking gets more frequent as
c. Rainforest (entrance chime) - As the visitor approaches, the unit will sing the melody to announce
the arrival of visitors.
d. Watchdog and Warning Siren - When Rex “sees” movement, the device will bark and a siren will
alarm for 20 seconds.
3. Turn on the “VOLUME” switch and adjust the required “RANGE.”
Note: Generally, the “RANGE” is adjusted to its maximum before delivery. Therefore, it needs no further
adjustment. In case it is too sensitive, turn the knob in a counter-clockwise direction to reduce the range.
Operation Instruction Caution: Rex Plus is designed for use indoors. The unit should be placed at a height
of 3-5 feet from the floor to obtain the widest range of detection. The position and sensitivity may be
adjusted until optimal performance is reached. Setup may take time and patience.
