The Murphy ST5AS-F 5-Point Selectronic Remote Alarm Tattletale is a general purpose annunciator suitable wherever a remote alarm and annunciation is required. Typical applications are in marine pilot houses to alert the crew of problems developing in engine, gear, bilge, auxiliary power plants, etc. As a side note, the ST5AS-LM (25700003) has been discontinued by FW Murphy. Your only choice is to purchase this item and simply remove the flange mounting bracket yourself. Repeater panels can be added for additional locations such as flybridge, on deck, galley or engineer's quarters. Each repeater panel can be acknowledged individually or alternate wiring allows for one master control to silence all repeater panels. Other applications include power plant control rooms or building maintenance, for remote drilling rigs, construction sites, agricultural and construction equipment. The ST5AS-F model includes a "Flange Mount" packaged with the annunciator. The flange mount provides a simple and inexpensive solution to mounting your remote alarm in a recessed panel location. This model features five (5) visual alarm points and a mini-siren alarm. Preprinted peel and stick nameplates for common faults are supplied with each unit. The ST5AS-F Tattletale accepts either normally open (N.O.) or normally closed (N.C.) contacts. You can mix N.O. and N.C. contacts. It also has a time delay available to lockout the audible alarm on startup. This unique alarm panel has wide ranging applications and can be grouped in many configurations. This model accepts 8-32 VAC or 8-40 VDC input voltage.
