Some methods can include detecting an ambient emergency condition, and responsive to detecting the ambient emergency condition, transmitting a wireless beacon signal, wherein a range into which the wireless beacon signal is transmitted is limited, and wherein a signal strength of the wireless beacon signal progressively decreases from a first part of the range, adjacent a source of the wireless beacon signal, to a second part of the range, displaced from the source of the wireless beacon signal. Additionally or alternatively, some methods can include receiving a wireless beacon message from a sensor device, determining the signal strength of the wireless beacon message, and based on the signal strength of the wireless beacon message, determining the range of the sensor device. ## Claims ### Claim 1 A method comprising: an electronic device receiving a wireless beacon signal transmitted by a sensor responsive to the sensor detecting an ambient emergency condition; the electronic device identifying a range level of the sensor based on a signal strength of the wireless beacon signal; the electronic device determining a category of the range level as immediate, near, or far relative to the electronic device; when the electronic device is operating under a first user type and the category of the range level is far, the electronic device directing a user of the electronic device to change directions towards the sensor; and when the electronic device is operating under a second user type and the category of the range level is immediate, near, or far, the electronic device directing the user of the electronic device to change directions away from the sensor, wherein a range into which the wireless beacon signal is transmitted is limited, and wherein the signal strength of the wireless beacon signal progressively decreases from a first part of the range, adjacent the sensor, to a second part of the range, displaced from the sensor. ### Claim 2 (depends on 1) The method of claim 1, wherein the wireless beacon signal includes a Bluetooth Low Energy advertising message. ### Claim 3 (depends on 1) The method of claim 1, further comprising the electronic device failing to receive the wireless beacon signal prior to the sensor detecting the ambient emergency condition. ### Claim 4 (depends on 1) The method of claim 1 further comprising the electronic device failing to receive the wireless beacon signal after the sensor fails to detect the ambient emergency condition for a predetermined period of time after detecting the ambient emergency condition. ### Claim 5 (depends on 1) The method of claim 1 further comprising: the electronic device receiving user input; and responsive to the user input, the electronic device transmitting instructions to the sensor to cease transmitting the wireless beacon signal. ### Claim 6 (depends on 1) The method of claim 1, wherein the wireless beacon signal includes information about the sensor. ### Claim 7 (depends on 1) The method of claim 1, wherein the wireless beacon signal includes information about the ambient emergency condition. ### Claim 8 (depends on 1) The method of claim 1, further comprising reporting the ambient emergency condition to an alarm monitoring system. ### Claim 9 A method comprising: an electronic device detecting and receiving a wireless beacon signal from a sensor device; the electronic device determining a signal strength of the wireless beacon signal; based on the signal strength of the wireless beacon signal, the electronic device determining a range of the sensor device; the electronic device determining a category of the range as immediate, near, or far relative to the electronic device; when the electronic device is operating under a first user type and the category of the range is far, the wireless beacon signal instructing the electronic device to change directions towards the sensor device; and when the electronic device is operating under a second user type and the category of the range is immediate, near, or far, the wireless beacon signal instructing the electronic device to change directions away from the sensor device, wherein the signal strength of the wireless beacon signal progressively decreases from a first part of the range, adjacent the sensor device, to a second part of the range, displaced from the sensor device. ### Claim 10 (depends on 9) The method of claim 9, wherein the wireless beacon signal includes a Bluetooth Low Energy advertising message. ### Claim 11 (depends on 9) The method of claim 9 further comprising failing to receive the wireless beacon signal outside of the range. ### Claim 12 (depends on 9) The method of claim 9 further comprising decoding the wireless beacon signal to identify additional information about the sensor device. ### Claim 13 (depends on 9) The method of claim 9 further comprising decoding the wireless beacon signal to identify additional information about an ambient emergency condition detected by the sensor device. ### Claim 14 (depends on 9) The method of claim 9 further comprising the electronic device displaying or emitting a notification message indicative of the range. ### Claim 15 A system comprising: a sensing device; and an electronic device, wherein, responsive to the sensing device detecting an ambient emergency condition, the sensing device transmits a wireless beacon signal into a limited range for detection by the electronic device, wherein a signal strength of the wireless beacon signal progressively decreases from a first part of the limited range, adjacent the sensing device, to a second part of the limited range, displaced from the sensing device, wherein the electronic device receives the wireless beacon signal, identifies a range level of the sensing device based on a signal strength of the wireless beacon signal, and determines a category of the range level as immediate, near, or far relative to the electronic device, wherein, when the electronic device is operating under a first user type and the category of the range level is far, the wireless beacon signal directs the electronic device to change directions towards the sensing device, and wherein, when the electronic device is operating under a second user type and the category of the range level is immediate, near, or far, the wireless beacon signal directs the electronic device to change directions away from the sensing device. ### Claim 16 (depends on 15) The system of claim 15, wherein the wireless beacon signal includes a Bluetooth Low Energy advertising message. ### Claim 17 (depends on 15) The system of claim 15, wherein the sensing device abstains from transmitting the wireless beacon signal prior to detecting the ambient emergency condition.
