Description
The ST Series Selectronic Tattletale annunciators are a simple and inexpensive answer to your remote alarm annunciator needs. Basic models ST5AS and ST10AS are general purpose alarms suitable for a variety of applications. Model ST8 gives first out annunciation of fault. Model STA16 is designed for generator set applications and can be configured to meet NFPA requirements for standby generators.
These compact Tattletale annunciators tell you by a flashing LED which variable malfunctioned. Many feature a pulsating
Mini-Siren to audibly alert you to the malfunction. The audible alarm is silenced by depressing the Alarm Silence push button, but the visual signal remains in operation until the fault is corrected and the contacts are cleared.
A test push button allows you to test all alarm LEDs. Because LEDs are solid state, cold light, electronic devices, they don’t burn out as incandescent light bulbs do.
Basic models accept 8-32 VAC or 8-40 VDC input voltage. Others are available for either
12 VDC or 24 VDC input.
Preprinted peel and stick nameplates for common faults are supplied with each unit.
Most of the Selectronic Tattletale annunciators accept either normally open (N.O.) or normally closed (N.C.) contacts. You can mix
N.O. and N.C. contacts on the same unit.
Two mounting styles are offered; a recessed panel mounting flange and a freestanding gimbal mounting. (Model STA16 is available only in flange mount).
All models except STA16 have a time delay available to lockout the audible alarm on startup.
These unique alarm panels have wide ranging applications and can be grouped in many configurations. Ask any Murphy sales/engineer for assistance.
Basic Operation
When an alarm sensor trips, the LED flashes and, if equipped, the Mini-Siren sounds. At the same time an output circuit is activated which allows you to connect an external relay to operate a general alarm, operate a shutdown device, etc.
Applications
• Marine
• Generator Sets
• Oil Field
• Agriculture
• Construction

BASIC: ST5AS, ST10AS and ST5DAS Series
Murphy Basic ST-Series Selectronic Tattletale annunciators are used 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.
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.
When a fault occurs, the contact operation causes the appropriate LED to flash and the audible Mini-Siren to pulse. At the same time an output signal is generated which allows an external relay to be wired to operate a general alarm such as a bell or horn.
Depressing the Alarm Silent button silences the local audible alarm and disconnects the output for the remote alarm. The flashing
LED remains in operation until the fault is corrected and the contacts reset. Alarm Silence/Test button allows you to test all LEDs.
Preprinted peel and stick nameplates for common faults are supplied with each unit.
5-Points
• ST5ASF (flange mount) and ST5ASG (gimbal mount)
• Provides 5 alarm points and output for remote alarm relay.
• Accepts N.O. and/or N.C. contacts.
• Use individually or gang for multiple applications.
• Input voltage 8-32 VAC or 8-40 VDC.
10-Points
• ST10ASF (flange mount) and ST10ASG (gimbal mount)
• Provides 10 alarm points and output for remote alarm relay.
• Accepts N.O. and/or N.C. contacts.
• Use individually or gang for multiple applications.
• Input voltage 8-32 VAC or 8-40 VDC.
Dual 5-Points
• ST5DASF (flange mount) and ST5DASG (gimbal mount)
• Provides two separate sets of 5 alarm points in one package. Each set of 5 points is powered separately from the other, but they share the same negative of the power source.
• Primary application is on twin engine boats. Since each set of alarm points is powered separately, if only one engine is running there is no alarm on the engine not running.
• Accepts N.O. and/or N.C. contacts.
• Input voltage 8-32 VAC or 8-40 VDC.

FIRST OUT FAULTS: ST8 Series
First out fault Tattletale tells you which monitored variable malfunctioned first. The fault is annunciated and locked in until reset by the operator. Applications include process monitoring such as compressors, pumps, generators, etc.
Preprinted peel and stick nameplates for common faults are supplied with each unit.
8 First Out
ST8F (flange mount) and ST8G (gimbal mount)
• Provides 8-point first out cause of shutdown Tattletale. A flashing LED indicates the cause of shutdown identified by the nameplate.
• Accepts N.O. and/or N.C. contacts.
• Includes SPDT dry contact output rated 2 A @ 28 VDC.
• Selectable sensor lockout for delay on startup.
• Input voltage 8-32 VAC or 8-40 VDC.
GENERATORS: STA16 Series
The STA16 is a multi-functional visual and audible 16-point alarm typically applied as a remote alarm. Its picture frame bezel allows for flush mounting into a control panel or customer supplied wall mounted pull box. Preprinted peel and stick nameplates for all common engine and generator functions allow for generic applications or for NFPA-110 REQUIREMENTS,
16-Points
• STA16 is a 16-point annunciator for generator sets.
• Provides 16 points of visual and audible alarms including built-in sensing for low battery voltage and battery charger malfunction.
• Accepts N.O. switch inputs
• Negative switch input.
