Murphy Selectronic Tattletale ST Series Specification Sheet

Selectronic
Remote Alarm Annunciators
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.
® Tattletale
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 circuit
is activated which allows you to connect an
external relay to operate a general alarm,
operate a shutdown device, etc.
