Selectronic® Flasher Alarm Light and Mini-siren
TL7 and SAH Series
Features
• High Visibility Flashing Red Alarm Light
or Audible Alarm
• 12 VDC or 24 VDC
• Panel Mount
• All Electronic Description
The Model TL7 is a panel mounted flashing alarm light and audible alarm driver. The TL7 helps protect the Murphy
Swichgage contacts from the very high inrush current of the lamp. It is available in 12 or 24 VDC for negative ground
systems. The SAH Mini-siren provides an audible alarm when fault conditions are detected by a Swichgage instrument. It
can be panel mounted and operates on 6–28 VDC.
Application
The TL7 Flasher/Light is used as a warning device on various types of industrial and mobile equipment. The Mini-siren will
give an audible warning when the TL7 operates, or it can be wired directly to the Swichgage contacts for audible only
alarm.

Typical Wiring Diagram
WARNING Before beginning installation of
this Murphy product:
 Disconnect ALL electrical power to the
machine.
 Make sure the machine CANNOT
operate during installation.
 Follow all safety warnings of the
machine manufacturer.
 Read and follow all installation
instructions.
Below is a typical circuit diagram for the TL7 Flasher/Light and SAH Minisiren. When the switch closes the lamp will flash and the optional Minisiren will pulse at the same frequency.
NOTE: typical wiring with negative ground. Although designed to
be used with Murphy Swichgage, the TL7 can be used with any dry
contact type switch.
How to Order
When ordering a TL7, voltage and polarity must be specified (see the
