DA-611TO (standard)
Transmitter/Internal Sensor
The Model DA-611TO Sensor/Transmitter contains the transmitting electronics, and sensor “wand” on a 50 foot direct burial cable.
The Transmitter box must be placed at least 5 feet above ground on a post, tree, or hung from any convenient point. The front of the
transmitter box should face the receiver for best range. The Sensor can be placed on top of the ground at the edge of the drive for
testing to confirm good operation, before burying the sensor and cable. The Sensor and cable should be buried about 5-6 inches to
prevent damage. The Transmitter uses 2 - AA alkaline batteries and the unit is active as soon as the batteries are installed. The unit
transmits continuous for about 1 minute after the batteries are put in and then is ready to act on Sensor inputs. The batteries can be
left in after this. When the battery voltage reaches 2.7 volts, the LO BATT lamp on the receiver will light and the batteries should be
replaced soon. The batteries should be put in near the receiver to confirm the system functions correctly. The receiver can be muted
by turning off the whistle switch or unplugging the chime to avoid annoying alarms while working on or moving the unit. After
installing batteries and confirming operation, the top cover and gasket can be put on. Place the gasket around the unit and install
the top cover until a small gap is seen between the cover and housing. Roll the gasket up to fill this gap and tighten the cover screws
to seal the transmitter box. If over tightened, the gasket may roll out of position. The System can now be placed in the desired
position.

If the system false alarms due to nearby traffic or electric lines, the Sensitivity can be reduced by turning the Sensitivity control
counter-clockwise slightly. A very small screwdriver is needed for this. The Sensitivity is factory set at maximum.
If interference is encountered from a neighbors system, the address can be changed by moving the jumper plugs located at the AD-
DRESS position from “0” to “1”. The corresponding address in the Receiver must also be changed to match. Switch one and/or two
of the Receiver address switches should be placed to the “ON” position.
The BIAS control should not be adjusted.
