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.

Approved ground

CONSIDERATIONS	● These protectors must be mounted indoors,
	● An approved electrical ground, such as a ground installed by the power
	service company, grounded building steel, or concrete-encased ground,
	is required for proper operation of the IROB protector. (For more
	information about approved ground, see the instructions that come with
	your IROB protectors.)
