Fire-Lite MS-9200UDLS System Test 11: EST Chime/Strobes!

System test 11 features special EST fire alarm chime/strobes, that's right, CHIME, fire alarms that are nice and quiet.

Fire alarm chime/strobes are used in special applications where a loud alarm is not necessary or can actually be a safety concern, for example, hospitals. When the fire alarms went off during school, how often did you jolt to the sudden loud noise? Imagine a delicate surgery suddenly interrupted by a screaming fire alarm.
