Narrative:
While working the cabin attendant coordinator position; the amass alarmed and said 'runway 8L go around.' runway 26R was active and amass was set to west confign. Aircraft landing runway 26R was rolling out; no other aircraft or vehicle a factor. Amass was put in limited mode. Operations manager comes to tower cabin attendant an hour later and says to let the amass rest; then put it back in service. I am now working local control. 15 mins later; the amass alarmed and said 'runway 8L go around.' again; we were landing west and aircraft was already rolling out on runway 26R. An amass alert gets your attention (it scares the hell out of you). It is warning you of an imminent situation that requires immediate action. Twice in 2 hours rattled me; and there was no reason for the alarm. There was definitely no good reason to put it back in service. This faulty piece of equipment needs to be replaced.
