REMOTE ALARM ANNUNCIATORS SELECTRONIC® TATTLETALE®

ST SERIES

• Provide Audible and Visual Alarm
• Simple and Inexpensive
• Wide Range of Applications
• Gen-Set Models Meet NFPA-99 and NFPA-110 Requirements

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 free-standing 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 circuits activated which allows you to connect an external relay to operate a general alarm, operate a shutdown device, etc.

APPLICATIONS

• Marine
• Agriculture
• Generator Sets
• Construction
• Oil Field

Description

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.
