Can two of these receivers be used in two different locations in the house using the same sending device?
1 answer-
ProductExpert11· 6 years ago
This will be an additional receiver used on the driveway alarm to allow you to have the receiver in two separate locations. You will set the units to the same code used for the transmitter.

2 Questions: Power Supply & LED reset
First Question - The complete system receiver (Item 510725) is described as coming with a 115 VAC transformer power supply. The description of this receiver says it's battery operated...does it not come with a power supply like the original?
2nd Question - A previous question asked describes that the receiver will not work if you do not reset the LED. What if you have this 2nd receiver in another location and only reset one of them when the system is tripped...will the system then work or do you have to reset the second receiver as well?
1 answer-
ProductExpert36· 12 years ago
The receiver does use a 115V AC power supply. The outdoor transmitters are the units that require batteries. You will need to reset each receiver to clear the LED visitor warning light, however it is not required to hit the reset button for the unit to function. It will still beep, and the light will blink each time someone new passes the sensor even if you don't reset the receiver.
