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.
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.
