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 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.
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 con-
tacts for audible only alarm.
