Page 9: Pre-Installation
System Orientation (page 1) and Installation (page 12) BEFORE installing the 3010R Series Intercom onto the apparatus. Taking a little time to plan the installation BEFORE installing the 3010R Series Intercom System may prevent many installation errors which could result in improper system IMPORTANT operation. -
Page 10: Headset Modules
P R E - I N S T A L L A T I O N HEADSET MODULES There are 2 different types of Headset Modules for the 3010R Series Intercom system (Figure 5). The HM-10 is the standard module and is designed for use inside the apparatus where it is protected from the elements. -
Page 11: Daisy-Chaining The Headset Modules
P R E - I N S T A L L A T I O N 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. -
Page 12: Routing The Ca Cables
P R E - I N S T A L L A T I O N ROUTING THE CA CABLES The path along which you intend to run the CA Cables from the Intercom to the Headset Modules should also be planned BEFORE the installation. The items below are some of the items to consider when planning where to route the CA Cables. -
Page 13: Intercom Connections
The 3010R Series Intercom requires at least +12 volts DC nominal (with a negative ground) at .5 amps. This Intercom will accept DC voltage as high as 36 volts. The 3010R Series Intercom comes with a Power Cable Assembly and a 1.0 amp, in-line fuse. We suggest connecting the Intercom power and ground to the apparatus power buses. -
Page 14: Intercom Adjustments
16 in this manual. These adjustments to the intercom MUST be performed by a Qualified Radio Technician to ensure proper operation of the 2-way radio and 3010R Series Intercom System. IMPORTANT OPTIONAL FOOT SWITCH The optional Foot Switch (FS-1) is used in situations where the user cannot, or does not wish to, use the headset mounted Push-T o-Talk (PTT). -

21. Connect the red wire (from pin 2) to one end of the supplied in-line fuse holder. 22. Connect the other end of the fuse holder to the vehicle's switched positive power supply. The 3010R Series Intercom System is installed and ready for connection to the radio. FIGURE 15: Power Cable Assembly... -
Page 18: Radio Connections
I N S T A L L A T I O N RADIO CONNECTIONS To ensure proper operation, the connection to the radio should be performed by a Qualified Radio Technician. IMPORTANT 23. If you are using a radio-specific interface cable, follow the directions included with the interface cable, then proceed with step 27 in this Installation Procedure. -
Page 19: Intercom Adjustments
A change to the radio programming may also be needed. The Firecom 3010R Series Intercoms have an adjustable delay between pressing the Push-To-Talk on the headset and the keying of the radio. -
Page 20: Auxiliary Input & Output
AUXILIARY INPUT & OUTPUT On the back of the 3010R Series Intercom, there are 2 jacks labeled “Aux In” and “Aux Out” (Figure 19). These jacks are 3.5 mm stereo (conductor) jacks. If a mono plug is inserted in this jack, it may damage the auxiliary device. -
Page 21: Installing The Remote Head
I N S T A L L A T I O N INSTALLING THE REMOTE HEAD One or two Remote Heads can be connected to the main base unit. The connections at the rear of the unit are identical in function. CA Cables of the style and pin-outs as the audio CA Cables will work to mount the remotes. - Page 22 I N S T A L L A T I O N 40. When mounting the Remote Head using the brackets, first plug in and thread the cable through the bracket assembly as shown in (Figure. 21). 41. Plug the CA Cable into the Remote Head and secure the panel with (4) machine screws and nuts to the front of the bracket.

Page 23: System Test
S Y S T E M T E S T This procedure tests all functions of the 3010R Series Intercom System and should be used to test the system for proper operation after installation. In the event of a system failure, it may also be used to help identify and isolate the exact symptoms before troubleshooting a prob- lem, and to test the system after repair work has been performed. - Page 24 S Y S T E M T E S T 11. Adjust the headset volume for a comfortable listening level. 12. Monitor radio communications. Verify that the incoming radio transmissions are the same volume as the intercom volume. 13. Repeat steps 4 to 12 for each headset/headset position on the apparatus. TEST RADIO COMMUNICATION Steps 14 to 16 are for Radio-Transmit Headsets only! These are the models FH-10 and UH-10, and have a red PTT on the ear dome.

Page 25: Intercom Operation
The mic is always active for intercom communications. Radio-T ransmit Headsets are typically used at the Driver , Officer and Pump Panel positions. There are 4 models of Radio-T ransmit Headsets available for use with the 3010R Series Intercom System: the UH-10, UH-10S, FH-10 and the FH-10S. There is a RED Push-To- Talk (PTT) button located on the ear dome which allows communication on the radio. - Page 26 I N T E R C O M O P E R A T I O N INTERCOM-ONLY HEADSETS The Intercom-Only Headsets receive both intercom and radio communications at all times, but are NOT radio-transmit capable. Intercom-Only Headsets are typically used at the jumpseat positions, due to the high ambient noise level at these locations (engine noise, etc.).
- Page 27 I N T E R C O M O P E R A T I O N HEADSET ADJUSTMENT The vertical fit of the headset is changed by adjusting the headband (FH models) or the headstrap (UH models). • Over-The-Head (FH) style headsets (Figure 24): These headsets have adjustable headbands with slide mechanisms located at each side above the ear domes.
