ADDITIONAL ACCESSORIESEASILY EXPANDABLE
The RDTD-20U offers expandability matched
by no other wireless alert system on the
market. With four channels and three
unique chime tones, users can add up
to nine TD-20U sensors to one RC-20U
chime box receiver. The fourth channel
on the chime box can accept three more
transmitters and acts as a latching alarm,
and will continue to chime until the user
turns it off. In addition, up to five RC-20U
receivers can be used per system.

The selectable 17ft. fan pattern or
50ft. beam pattern on the battery-
operated TD-20U make it a versatile
option for perimeter awareness
These measurements were obtained with receivers & transmitters mounted 7ft. above level
ground without obstructions. Natural & man-made obstructions and other environmental
factors do shorten transmission ranges.

The TR-20U is a hardwired repeater for the RCTD-
20U (Wireless 2000). It extends the range between
either the TD-20U, TC-20U or TS-10U, and the
RC-20U receiver of up to 1,000 additional feet
(depending on device, line of sight).
The TS-10U is a push button, battery-powered
transmitter for the RCTD-20U (Wireless 2000). It
allows the user to send a signal back to the RC-
20U chime box and creates a chime for notification
purposes, as well as triggering or releasing other
devices such as magnetic door locks and lighting.
The TC-10U is a battery-powered door/window
contact and wireless transmitter for the RCTD-
20U (Wireless 2000). When used as a wireless
transmitter and installed in the back-box of any
of OPTEX’s battery operated detectors, extended
detection range and wireless notification to your
RC-20U chime box is achieved. Instantly monitor
larger areas with minimal false alarms for a greater
sense of protection. When used as a door contact,
the TC-10U will send a signal to the RC-20U receiver
chime box. This gives the user a notification when
the door is opened, and is perfect for high traffic
areas around entrances where an above door
sensor is not practical.
