GARAGE DOOR MONITOR OPERATION
When the receiver is powered up, both red and green LEDʼs
will flash once. The receiver will then show a solid green LED
until it receives a signal from a programmed sensor. The receiver
will display the current status of the programmed door sensor. If
no door sensor(s) is programmed to the receiver, the green and
red LED will flash simultaneously. See Learning section.
The sensor sends a closed signal when the garage door is
closed (vertical) and an open signal as the sensor changes to
open (horizontal) position.
Up to 4 door mounted sensors will work in conjunction with one
receiver.
The red LED will flash once every half-second if one or more of
the programmed sensors are not in the closed position. The
green LED comes on steady only when all the programmed
sensors are in the closed position.
NOTE:
The system will sometimes take a few seconds to send a
signal. The sensor updates the receiver by transmitting an open
or closed signal every few minutes.
LEARNING MORE THAN ONE SENSOR(S)
1. Door must be closed and the green
LED on steadily.
2. Press and hold the learn button for 2
seconds, the receiver will enter the learn
mode. The green LED will flash on and
off in 1/2 second increments.
3. The additional sensor(s) must be moved
from a vertical position to a horizontal
position or vice versa.
4. Both green and red LEDʼs will turn on for 1 second to indicate
a successful learn. Upon success, the receiver immediately
exits the learn mode and returns to normal operation.
5. If no signal is received within 30 seconds, the receiver will exit
the learn mode and return to normal operation.
ERASING OR CLEARING THE MEMORY
1. Unplug the small plug from the AC adaptor on the
indoor receiver.
2. Make sure the AC adaptor is plugged into a wall outlet.
3. To erase the memory of all programmed sensors, press and
hold the learn button while plugging the small plug on the AC
adaptor into the indoor receiver.
4. Both red and green LEDʼs will flash simultaneously. This also
indicates that no sensor(s) are in memory.
5. Proceed to Step 2 of
Learning More Than One Sensor
to
program the sensor to the receiver.
TROUBLESHOOTING
The sensor battery must be replaced every year to assure
consistent operation. Flashing of the red and green LEDʼs in a
special sequence normally indicates intermittent operation or a
dead battery.
Loss of signal:
The sensor sends a signal periodically to
synchronize to the receiver. Should the receiver not receive the
signal in approximately 20 minutes, the red and green LEDʼs will
flash as follows. The green LED will flash once, then the red LED
will flash one to four times depending upon the sensor
number. This indicates the receiver has not received the signal
from this sensor for over 20 minutes and therefore
requires attention.
If replacing the battery does not rectify the issue, move the
receiver into the garage for additional troubleshooting. If the
monitor works flawlessly in close proximity, the sensor(s) signal is
being either blocked or interfered with in the previous location
and may require placement in a room closer to the garage
door(s).
Garage Door Monitor system just installed:
The sensor and receiver set are factory coded prior to shipment
and should work out of the package. If you encounter a situation
where the sensor and receiver work properly upon initial
installation, but show a loss of signal after 20 minutes you may
have an additional factory code in the receivers memory. In this
instance, the receiver will then appear to be unresponsive to the
sensor. In this instance, do the following:
1. Clear Receiver Memory – See
Erasing or Clearing the
Memory
section. Upon clearing memory, the receiver will
power up and show simultaneously flashing green and red
LEDʼs – this indicates that memory is cleared.
2. Proceed to Step 2 of
Learning More Than One Sensor.
Note
that the procedures to learn 1 sensor or multiple sensors are
the same.
If the receiver is still showing a loss of signal after following the
above procedure, then the receiver is located too far away from
the sensor. Relocate the receiver closer to the sensor.
Garage Door Monitor suddenly malfunctions after working
properly:
The sensors battery power is low. Replace the battery.
OPTIONAL ACCESSORIES
You can purchase additional sensors if you have more than one
garage door. The receiver will learn up to 4 sensors and the red
light will flash if any one of the garage doors is open.
