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.
