B. System Components Overview

System Components

The following components (in addition to a suitable power supply) are typically utilized to make

up the Selective Call Intercom System (see Figure 2).

• Selective Call Intercom Module: This module is typically installed in the On-Q

enclosure and is considered the System Command, Communication and Power Router of

the system. All Room Units, Patio Units and Door Units are connected directly to the Module

via “home run” style single Cat 5e cabling. The Intercom Module also supplies power to the

entire SCI System. Up to eight units of any combination are supported by each module and

modules may be cascaded three times, for a total system support of up to 32 units.

• Selective Call Room Unit: Through the LCD display, this unit provides both basic

intercom communication functions such as talk, talk to door (if Door Unit is installed),

monitor, mute, and advanced functions such as dynamic sorting of users or monitoring

multiple rooms at the same time. Up to 8 Selective Call Room Units can be installed per

Selective Call Intercom Module, and up to 32 per system.

• Selective Call Patio Unit: This unit also provides similar basic Room Unit functionality in

a weather resistant wall mounted package for your patio. For security reasons, it does not

support the door release function. There are no specific limits as to the mix of Room Units

and Patio Units up to the physical limitation of 8 per module and 32 per system.

• Selective Call Door/Video Door Unit:

This unit allows a visitor to the home to press the

door chime button on the unit to notify the occupants of their presence. The occupants can

then initiate a two-way communication with the visitor, see the visitor (Video Door Unit only)

and even open the door (requires electronic door release device, not included). Up to 20

different door tones can be selected as the door tone that is played when the door chime

button is pressed. There are no limits to the mix of Room, Patio and Door Units up to the

physical limit of 8 per Distribution Module and 32 per system.
