Installing and Wiring Telephones
May 2003
Connections to 24 Out-of-Building Telephones
Off-Premises Protection Requirements
Both building entrances require carbon block or equivalent protection and sneak current
protection. Protection can be provided by:
•
a 4-type protector, which is equipped with a heat coil
•
a 3-type protector plus a separate sneak current protector
The 4-type protector is the preferred device. For installations not using primary protection,
4-type protectors should always be used. When the 3-type protector is already installed, a
separate sneak current protector is required.
