1. A surge protection system, the surge protection system comprising:
a surge protection device including a flag movable between a ready state corresponding to normal operation of the surge protection device and a triggered state corresponding to an end-of-life state of the surge protection device; and
a surge protection monitor system that includes a sensor, the sensor including: a switch, and an electronic transmitter configured to wirelessly transmit signals based on a state of the switch;
the sensor having an installed configuration in which the sensor is secured to the surge protection device with the switch aligned to detect a position of the flag that corresponds to the triggered state; and
with the sensor in the installed configuration, the electronic transmitter being configured to wirelessly transmit an end-of-life signal to indicate that the surge protection device is in the end-of-life state, in response to detection of the position of the flag by the switch.
