Claim 4:
5. A premises security system, comprising:
a premises device located at a premises;
an on-site primary control device located at the premises and configured to communicate with the premises device and an on-site secondary control device located at the premise, the on-site secondary control device being physically separated from the on-site primary control device, the on-site primary control device comprising on-site primary control device processing circuitry configured to:
receive a detection signal from the premises device;
determine that an alarm event has occurred based on the detection signal;
transmit an alarm event signal to the on-site secondary control device for temporary storage; and
trigger a predefined timer, an expiration of the predefined timer configured to cause transmission of the alarm event signal to a remote monitoring center; and

wherein the on-site secondary control device comprises on-site secondary control device processing circuitry configured to:
receive the alarm event signal from the on-site primary control device;
temporarily store the alarm event signal;
determine that a criterion associated with the premises security system is met, the criterion comprising at least one of:
a signal strength of a connection between the on-site secondary control device and the on-site primary control device being below a first threshold value;
a signal to interference and noise ratio of the connection between the on- site secondary control device and the on-site primary control device being below a second threshold value;
a power level of the on-site primary control device or the on-site secondary control device being below a third threshold value; or
an accelerometer of one of the on-site primary control device or the on-site secondary control device detecting an acceleration greater than a fourth threshold value; and

in response to determining that the criterion associated with the premises security system is met, transmit the alarm event signal to a remote monitoring center.
