1.7 MC-Series Standard Capacity system cabinet

The MCSC system cabinet is a short 19” equipment cabinet with lockable front and

rear doors, 4,000 BTU air conditioning unit, allowing access to the system without

opening the doors. The cabinet is rated for operating in an environment of -32° to

+52° C ambient. External RF connectors are flush with the rear of the enclosure in a

recessed bulkhead. For more information, refer to the cabinet manufacturer’s

documentation shipped with the MCSC system.

1.7.1 Air Conditioning

The MCSC system comes with a 4,000 BTU air conditioning unit installed on the

front door. Refer to Appendix C , Section C.1.11 (Air Conditioning Cabling) for

wiring information.

1.8 Non-RadioFrame Networks Hardware (must be installed)

Non-RadioFrame Networks hardware for the MCSC system must be procured and

then installed in order for the MCSC system to be complete.

1.8.1 integrated Site Controller (iSCIII (must be installed))

The MCSC system uses a integrated Site Controller or iSCIII, which is connected

to the macro network through a Channel Service Unit (CSU). The connection

between the iSCIII and the MCSC system is via a coaxial interfaces. The first is a

10Base2 Ethernet connection to provide data communications. This connection is

made directly to the MCSC system and does not require an external media

converter.

For more information about the iSCIII, refer to the Motorola document Gen 3 Site

Controller System Manual, 68P80801E30-O.

1.8.2 Environmental Alarm System (EAS (must be installed))

The Environmental Alarm System (EAS) provides a central location for site alarm

signal processing. The EAS monitors site environmental conditions, including AC

power, smoke alarms, intrusion alarms, antenna tower lights, etc.

Each of the site alarm contacts are normally closed and connected to the EAS

through a 50-pin Champ cable that connects to a punch block. All alarm contact

pairs must be dry (isolated from ground). Most alarm connections are inputs.

Outputs provide a dry relay closure rated at 0.5 A, 30 Vrms or 60 VDC, 10 VA

max.

Plan to implement EAS alarm blocks, wiring and sensors as required depending

on the installation:

• Plan on providing standard facility environmental sensors, wiring, and

connections. The alarm blocks can be installed inside the enclosure, which

contains a 66-connection punch down block (Figure 1.17).
