1. A first playback device comprising:
one or more processors;
a network interface;
one or more audio amplifiers configured to drive one or more speakers; and
tangible, non-transitory computer-readable media comprising program instructions encoded therein, wherein the program instructions, when executed by the one or more processors, configure the first playback device to:
play audio content in synchrony with a second playback device, wherein the first playback device plays the audio content via the one or more audio amplifiers and the one or more speakers at a first volume level that is lower than or equal to a first volume limit, wherein the second playback device plays the audio content at a third volume level that is lower than or equal to a third volume limit, wherein the first volume limit is adjustable separately from the first volume level, and wherein the first volume limit is less than a maximum playback volume of the first playback device;
detect an activation of an emergency alarm while the first playback device is playing the audio content at the first volume level in synchrony with the second playback device; and
in response to detecting the activation of the emergency alarm while the first playback device is playing the audio content at the first volume level in synchrony with the second playback device, (i) activate a second volume limit, wherein the second volume limit is less than the first volume limit, (ii) when the first volume level is greater than the second volume limit, reduce a playback volume of the audio content at the first playback device from the first volume level to a second volume level that is lower than or equal to the second volume limit, wherein the second volume level is adjustable separately from the second volume limit, (iii) cause the second playback device to reduce the third volume limit to a fourth volume limit, and (iv) when the third volume level is greater than the fourth volume limit, cause the second playback device to reduce a playback volume of the audio content at the second playback device from the third volume level to a fourth volume level that is lower than or equal to the fourth volume limit.
