3.2 Collector and Concentrator Location Planning
When planning an installation, it is important to locate a proper place for the concentrators and
collectors. Collectors should be mounted in telephone or service areas that are near the sensory
networks they service. The sensor wires will run from the collectors to the various sensor locations
throughout the facility. The concentrator(s) should be mounted in a location central to the
collector(s) to minimize the length of collector network runs. In smaller installations, collectors
and concentrators may all be located in the same place in a telephone or utility closet. The location
selected should have easy access for servicing, but be secure against tampering by unauthorized
personnel. Make sure the locations selected are free from extremes of heat, cold and moisture, as
with any electronic equipment.
Caution:
Collectors may be affected by high watt radio or paging antennas. Do not
place a collector in close proximity to one of these antennas.
3.2.1 Collector Network Length Limitations
There must be no more than four collectors on any one concentrator as shown in the RS-485 loop
display below. Collectors should not be placed more than 1000 feet apart. The total length of the
collector network (from the Concentrator to the last Collector in the chain) must not be more than
3000 feet.
3.3 Sensor Location Planning
One of the most important steps in an installation is planning the sensor locations. A complete
understanding of sensors and badges is very helpful in designing an effective system. There are
several things to consider when planning the sensor locations.
