Daisy-Chaining The Headset Modules - Firecom 3000C Installation & Operation Manual

DAISY-CHAINING THE HEADSET MODULES

Daisy-Chaining the Headset Modules is a method used to increase the number of headset
positions available, or a method of reducing the number of cable runs and the length of the
cable runs. Daisy-Chaining the Headset Modules is easy to accomplish, but must be well
thought out in advance considering the following requirements:
• The Headset Modules in a Daisy-Chain must be connected in a SPECIFIC
manner (Figure 5).
• The CA Cable from the Intercom unit should ALWAYS be plugged into the
Headset Module via the modular jack under the label.
• The modular jack on the other end of the Headset Module, is for the CA Cable
which leads to the next Headset Module in the Daisy-Chain.
• DO NOT mix headset types (Intercom-Only vs. Radio-Transmit) that are
plugged into a Daisy-Chain.
• A maximum of 2 Intercom-Only Headsets may be plugged into a Daisy-Chain
at any time.
• You may have more Headset Modules in the Daisy-Chain, but NEVER plug
more than 2 Intercom-Only Headsets into the Daisy-Chain at any one time.
A maximum of 1 Radio-Transmit Headset may be plugged into a Daisy-Chain
•
at any time.
• You may have more Headset Modules in the Daisy-Chain, but NEVER plug
more than 1 Radio-Transmit Headset into the Daisy-Chain at any one time.
Improper Daisy-Chains in a system may result in operational problems and reduced
system performance. If you have any questions regarding Daisy-Chains, contact your
local Firecom Dealer for more information.
