Network Requirements
Network Requirements
Certain criteria may affect the number of transmitters required for a
network. The following points have an impact on installation:
•
The type of area covered; whether it is an open garage, wall type
(full or half concrete, gypsum, etc.) and ceiling height.
•
Area to cover; maximum distance between transmitters is 30.5 m
(100 ft) therefore, the greater the area, the more transmitters are
needed.
•
Depending on the distribution and layout of your network, more
than one 301C controller may be required.
•
If the controller (or relay module) is installed in a closed area, away
from the central transmitter area, two additional transmitters are
required outside of the enclosed area to act as signal relays.
Determining the Number of Transmitters
The number of transmitters required is determined by a unit’s
communication radius, the area where it will be installed and by the
degree of protection desired (an increased number of units offers
increased security).
Sensor Surveillance Area
Redundancy is key to ensuring the strength of the network.
Adding additional transmitters at key points ensures that the
communication link will be maintained should one transmitter
communication link fail.

Honeywell Analytics recommends installing additional
transmitters near the ceiling (at ramp entrance points)
that act as transmission links when communication is
weak.
