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.

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.
