A device and a method used during installation of a security system that allows the security system control panel to learn the IDs of the wireless transmitters in the security system without receiving an RF transmission from the wireless transmitter. The installation device comprises a power supply means, a first and second interface means, monitoring means for monitoring the current drawn from the power supply means, and processing means for producing a digital signal based on the current monitored. The first interface means connects the power supply means of the installation device to the battery terminal of the transmitter, and the second interface means connects the output of the installation device to the control panel. The monitoring means, comprising a resistor and a comparator, monitors the current drawn from the power supply means, wherein the current drawn corresponds to the data transmitted by transmitter. The resultant digital signal is processed by a microprocessor and transmitted to the control panel via a common interface bus. The control panel then stores the ID of the transmitter.
