Section I: Introduction CUTION: Certain dangers to human safety and to equipment may occur if some equipment is stopped without pre-warning. It is recommended that monitored functions be limited to alarm-only or to alarm before shutdown.. This manual is directed to the design, installation, and operation of alarm systems using the STS family of alarm annunciators and accessories.. The Murphy STS family of alarm annunciators are designed to indicate the cause of an alarm with both an audio and visual signal. The audible portion of the warning has an alarm silence so the operator can turn off the alarm, but leave the flashing warning light on. selectable lockout time delay is provided so that when power is applied the audible alarm does not operate and the circuit does not latch on. This feature gives the monitored variables of an engine time to reach their desired normal levels. The built-in lockout time delay feature may be bypassed by the user, see Section IV: Installation Operation Electrical #, # and #. nother feature is that a momentary alarm contact will register and lock in until the larm Silence/Lamp Test button is operated. Remote Silence feature can be wired for all models, see Figures and Typical Circuit Diagrams(p-). C. The STS model is a five-function alarm annunciator with an larm Silence/Lamp Test button. The ST0S model is a ten-function alarm annunciator with the larm Silence/Lamp Test button. The STDS model consists of two STS s in one package with separate positive power supplies and a common negative. The STDS has a common alarm and larm Silence/Lamp Test button. The STDS is a convenient device for monitoring two separate engines within the same package. The three different types of mounting for the STS, ST0S, and STDS families are listed below. DESIGNTION LM F G MOUNTING Less Mounting Flush mount bezel rotating Gimbal is provided as a mounting device uxiliary devices designed to be used with the STS electronic TTTLETLE family include the TDST - and TDST 8-0.. When two or more STS Selectronic Tattletales are wired together (Example: Pilot house and fly bridge) customer supplied diodes must be installed between each Tattletale to protect the circuitry in each device from the feed back voltage from the other devices.. TDST - Time Delay. single point - second delay. The TDST - is commonly used to delay bilge alarm signals to compensate for roll and pitch of marine vessels.. TDST 8-0 Time Delay. single point 8-0 second delay. Section II: Specifications. STS Family. Power Requirements a. Voltage 8-0 VC, 8-0 VDC b. Current i.

MINI-SIREN audio alarm. larm silence function that turns the MINI-SIREN off but leaves the alarm flashing. dditional alarms also sound the MINI-SIREN even if it has been silenced.. udio alarm lockout time delay at start up (power on): to seconds (may be bypassed by the customer, see Section IV below; Electrical #,, ).. The mounting options include less mounting (LM), flush mounting (F), and gimbal mounting (G).. larm relay driver for customer supplied relay ( V maximum, coil not to exceed 00 m). Relay voltage same as input. 6. Lamp Test Function lights larm s while depressed.. The STS has a five-point alarm with generic function labels for each. C. The ST0S has a ten-point alarm with generic function labels for each. D. The STDS has two five-point alarms with generic function labels for each. The STDS has a common connection for the MINI-SIREN, larm Silence/Lamp Test function, and negative for the power supplies. Two remote alarm relay outputs are provided. lthough it uses two separate positive voltage inputs, the negative must be common to each power supply. STS-90N page of 8
Section IV: Installation Operation N.C. Switch: open for alarm. FS WIRING N.O. Switch C Sensor is common must go to negative. Figure N.O. Switch: closed for alarm. Sensor is common must go to negative.. Electrical Typical customer switch wiring for the STS family of alarm annunciators at terminals and are shown in Figure. Switch wiring should be run separate from other wires; DO NOT run along with C power wires since voltages, that may be induced into the switch wires, may exceed rating and cause damage to circuits. Specific circuit diagrams for the STS, ST0S, and STDS are listed in Figure below. Figure shows the wiring for a normally closed switch connected to input terminals and. The factory supplied metal link must be removed to use this wiring. When the switch opens the alarm will sound. Figure shows the wiring for a normally open switch connected between terminal and the negative power input. The metal link is connected between and. When the switch closes the alarm circuit turns on. Figure C shows the wiring for a normally open switch which is the same as Figure except two wires are run from the STS Terminal and to the switch. With this closed loop wiring the circuit monitors the wires as well as the switch. If the circuit is opened due to a loose connection or broken wire, the alarm will sound. nytime the normally open switch is closed to the negative side of the power supply the alarm sounds. Figure D shows how to wire a small control transformer to supply C power to the STS family. If an alarm relay is used, the relay coil should be the same voltage as the transformer secondary, but it must be a DC coil. n C coil relay will not work. Wire alarm relay as shown in Figures & (p. ).. The STS circuit diagram is shown in Figure (p. ). This figure shows the STS monitoring one engine. larm system is turned on with a manual ON/OFF switch. n alarm relay is provided to sound a remote alarm bell. Start-up time delay is bypassed with a jumper from # to #.. The ST0S circuit diagram is shown in Figure (p. ). This figure shows the ST0S used to monitor two generator engines and four bilge levels. The common connections of the engine SWICHGGE instruments are wired through a fuel pressure switch so the alarm switches are disconnected while the engine is not running. The four bilge switches are active at all times. The start-up time D.C. OPERTION Volt 00 ma. Transformer. Sensor is common must go to negative. delay is bypassed with a jumper from #6 to #. n alarm relay, if used, is wired to # and #.. The STDS circuit diagram is shown in Figure (p. ). This figure shows the STDS monitoring two main engines. The ON/OFF switches may be either manually operated or could be speed or fuel pressure switches, which would turn on the alarm system when the engine is started. The start-up time delay is used to prevent normal start-up alarms (Start-up time delay is bypassed with a jumper from # to #.) The negative of power supplies must be common. Note: When power is removed or to reset the equipment, wait -0 seconds before applying power again to allow the internal components to stabilize.. Mechanical Specific types of installation for STS, ST0S, and STDS with F and G options are listed below.. The mechanical installation for the STS-F is shown in Figure (p. 6). The mechanical installations for the ST0S-F and ST-DSF are shown in Figure 6 (p. 6). Four screws, 6- x /8 in. (supplied), are used on the flush mount bezel to connect it to a mounting panel or dash.. The mechanical installation for the G option on the STS, ST0S, and STDS is shown in Figure 7 (p. 7). Three holes are provided in the base of the Gimbal for installation.. The mounting of the TDST - and TDST 8-0 is shown in Figure 9 (p. 7). Two #8 screws can be used to attach a TDST to a mounting panel or dash. C. Directions for pplication of Preprinted larm Labels If you have received labels with the unit and you wish to apply these labels in certain designations follow these steps to insure a proper application:. e sure face is clean and free of oil.. Peel one label at a time and position on the ST unit.. efore pressing down, be sure label is correct.. Rub down firmly, and leave untouched for several hours. The pressure sensitive labels are permanent when properly applied. D. uxiliary Installation description of the installation for the TDST - and TDST 8-0 Time Delay, is the following:. TDST - is used when a - second time delay is needed. typical wiring diagram for the TDST - and TDST 8-0, with the STS family, are shown in Figure (p. 8).. TDST 8-0 is used when a 8-0 second time delay is needed. The wiring diagram is the same as the TDST - in Figure.
