Foot Switch (Optional); Radio Connections - Firecom 210 Installation & Operation Manual

Foot Switch (optional)

A radio Push-to-Talk (PTT) foot switch option is available from Firecom when a headset radio PTT is not desired.
The foot switch is installed to the headset module in a similar fashion as the headset module daisy-chain installation.
See "daisy-chaining headset modules" in the System Wiring section of this document. Depressing the foot
switch will initiate radio transmissions of the headset plugged into the headset module where the foot switch is
installed.
The foot switch is installed to the headset module using a CA cable and RJ-12 connector. You will need to open
the headset module and remove the plastic tab which covers the access hole to the second modular jack.
Warning
The CA cable from the intercom should always be plugged into the headset module on the
"Firecom" label side.

Radio Connections

A mobile radio may be connected to the intercom by using the radio port on the back of the unit. A MR interface
cable, with an un-terminated end, is supplied with the intercom. For independent wire descriptions, see
Appendix A.
Warning
To ensure proper operation, the connection to the radio should be performed by a qualified
radio technician.
Some radio specific interface cables are available for common model radios. For a list of interface cables, please
visit www.firecom.com and click on the Product Support section of our web site or contact our service department
at 800-527-0555.
When installing an MR cable, tighten the two screws on the plug of the cable.
Warning
If the screws are not properly tightened, the 9-pin plug may vibrate and cause problems with
transmission, reception, or other radio functionality.
