1. DITEK’s Low Voltage Line Protector series of signal,
data and loop circuit surge protectors provide strong
protection in a compact hard wire package. Applications
include protection of 4-20mA current loops, alarm panel
NAC, SLC and IDC loops, and burglar alarm panels.
The DTK-2LVLPF is specifically designed to protect
24V SLC loops into the alarm panel, preventing induced
surges from damaging sensitive (and expensive) control
boards. Its low-current fusing provides extra protection
for sensitive fire alarm panels.
