Wheelock FS6-61 - FireAlarms.tv - jjinc24/U8oL0's Fire Alarm Collection

Category : Silent Knight

Personally, I think that the Silent Knight logo on the head of this smoke is a bit ugly.

Category : Siemens

This is the second alarm of this model which is in my collection.

Category : Simplex

Oddly enough, the model number on this particular smoke doesn’t fit the typical pattern for Simplex devices.
