1. Cellular Alarm Communicators are becoming more
widely used in the fire alarm industry. In many
installations an external antenna kit is added to
attain the required wireless signal strength. Since
the antenna is external to the building, it becomes
an avenue for harmful transient surges to enter the
system through the coaxial antenna cable.
DITEK’s VSPN surge protector combines state-of-
the-art hybrid circuit technology with N type
connectors to protect a variety of coaxial devices.
