In-Range, Out-of-Building Voice Termianl and Protectors
DESCRIPTION You can place a voice terminal in another location, outside of the main
building, but within 1000 feet of the MERLIN 11 system control unit. In order
to protect both this In-Range, Out-of-Building (IROB) voice terminal and the
control unit from exposure to lightning, contact with power lines, or power
currents induced by nearby power lines, you must also install two Model TII
341 IROB protectors.
See the example in Figure 2-24. Install one of the IROB
protectors where the cable from the control unit leaves the building, and the
other where the cable enters the building in which the IROB voice terminal
is located.
