Before installation, a room, closet, or other area must be designated where the system control unit can be mounted on the wall. The area must meet the environmental requirements in Table 1–1.

Table 1–1. Environmental Requirements

Conditions

Requirements

 

 

 

Distances

Within 25 cable feet (7.6 m) of the network interface

 

(cannot be installed outdoors)

 

 

 

Within 1000 cable feet (304.8 m) of telephones

 

 

Within 5 cable feet (1.5 m) of a dedicated AC power outlet

 

(one outlet for every carrier)

 

 

 

 

 

Heat

Fully loaded basic carrier: 500 Btu/hr (35 cal/sec)

 

Dissipation

Fully loaded 2-carrier:

1000 Btu/hr (70 cal/sec)

 

 

Fully loaded 3-carrier:

1500 Btu/hr (105 cal/sec)

 

 

 

 

 

Power

Basic carrier: 117 VAC

60 Hz ± 5%

160 W

5.4 amps

 

2-carrier:

117 VAC

60 Hz ± 5%

320 W

10.8 amps

 

3-carrier:

117 VAC

60 Hz ± 5%

480 W

16.2 amps

 

one properly grounded outlet needed for each carrier

 

Additional outlets may be needed if installing printers and PCs.

 

 

 

 

Temperature

40° through 104°F; 4° through 40°C

 

 

 

(optimal temperature 60°F; 16°C)

 

 

 

 

 

 

Humidity

20% through 80% relative humidity

 

 

 

 

Ventilation

Allow at least 1 in. (2.5 cm) of space on the right and left sides of

 

the control unit and 12 in. (30.5 cm) above and below the

 

control unit to prevent overheating.

 

 

!CAUTION:

The AC outlet for the control unit should not be switch-controlled. Plugging the control unit into an outlet that can be turned on and off by a switch can cause accidental disconnection of the system.

The AC outlet must be properly grounded by using an AC receptacle for a 3-prong plug.

Do not install the control unit outdoors.

Do not place the control unit near extreme heat (furnaces, heaters, attics, or direct sunlight).

Do not expose the control unit to devices that generate electrical interference (such as arc welders or motors).
