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 pro-

vides 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 con-

tacts for audible only alarm.
