2 System Description 2.1 IM-900 The Setcom System 900 is a vehicular intercom/radio mixer designed specifically for fire apparatus and other emergency response vehicles. It provides noise-attenuating dual-speaker headsets with a Noise Reduction Rating of 24dB for hearing conservation. It improves communications in-route by providing radio interface through a noise-canceling boom-mounted microphone.
2.3 System Description IM-900E The IM-900E is similar to the IM-900 with a few important exceptions. The 900E has a total of four radio access circuits as compared to two for the IM-900. An AUX port on the IM-900E replaces the built-in footswitch port on the IM-900.
A footswitch port allows either/both the driver and Captain to key the radio with a footswitch or push button stations. The IM-900’s small size (6.5”W x 5.0”H x 1.75”D) and lack of adjusting controls allows mounting it anywhere in the vehicle.
• Aerial Advantage™ Antenna - Setcom offers the only wireless system on the market with the option to have an advanced antenna designed to optimize the wireless connection between the cab of the apparatus and an aerial platform or ladder.
3.6 6B-900 and 6B-901 Series Headsets The 6B-900 series is a single ear muff, over the head, reversible cable dress headset. Standard configurations include a radio transmit headset and an intercom only headset, the 6B-900 and 6B-901 respectively. The reversible cable dress eliminates the need for a Right or Left style.
The ES-900-xx and ES-900RA-xx are commonly used to remote the Driver and Officer locations when the IM-900’s location is hidden. They can also be used in jump seat locations where obstacles in the compartment make it difficult for two crewmembers to both plug into a dual jumpseat station.
One end of the JS-900-xx is fitted with a twist-lock connector that mates with the "REMOTES" port of the IM-900 or the expansion port of a JS-901-xx. There are a variety of lengths for the JS-900-xx, with xx denoting the length. A red washer is used behind the Tip-Ring-Sleeve (TRS) female panel mount jack to indicate this is an intercom-access/radio-listen port.
JS-901-xx, but it allows a TS-900 Tailboard Station to be plugged in. If a series of stations are being daisy-chained to the "REMOTE" port of the IM-900, the JS-902-xx is always the second-to- last station in a chain of stations, with a tailboard becoming the last station.
PS-900-xx with the exception of the cable termination. This version terminates with a three-conductor phone plug which can be plugged into any of the Headset Ports on an IM-900 or IM- 900E. This Pump Panel Station is normally used with an IM-900E system where a second Pump Station or a Turntable Station is required.
The MACB-xx and LMACB-xx Microphone Adapter Cables allow plug-in installation, retention of the hand mic, and easy exchange of the radio for maintenance. Use of a Setcom MACB will not void a new radio warranty and eliminates problems that can occur if a radio cable is mis-wired.
Cable on those radios with this accessory connector provision. A terminated radio cable allows plug-in installation, retention of the hand mic, and easy exchange of the radio for maintenance. Use of a Setcom radio cable will not void a new radio warranty and eliminates problems that can occur if a radio cable is miswired.
“RADIO” port of the IM-900. There are two or three one-foot cables terminated with the mating connector to the “IM-900 end” of the 9RC Radio Cable or MACB- xx Microphone Adapter Cable. If the radios being connected to the Radio Select Module have different transmit level setting, a separate Rim-900-BAL will be needed for each radio.
When a single Push Button Station is mounted, it can be wired to key either the Driver or Captain's position. Although the IM-900 can be mounted in different orientations, the Driver has a pre-determined port due to the fact the Driver's Port is paralleled with the Pump Station Port.
3.29 PRAC-9xx Portable Radio Adapter Cables A PRAC-9xx allows any system 900 radio transmit headset to be used with a portable radio at the fire scene. The PRAC-9xx is fitted with the radio connector, a jack for receiving the headset plug, and clothing clip. A radio PTT is fitted to the PRAC for keying the portable.
4 Representative Systems All Setcom Intercom Systems are delivered with a System Diagram specific to the components ordered. Be sure to have this System Diagram in hand before starting your installation. If your intercom system was installed by the apparatus original equipment manufacturer, the Setcom System Diagram should be included with your manual. If you cannot locate the System Diagram specific to your installation, contact Setcom at 1-650-965-8020 ext.
(MAC or Radio Cable) may be required to allow the IM-900 to correctly modulate this new radio. You will need to call our toll-free service line 1- 888-673-8266 ext 603 (888-6SETCOM ext 603) to determine the correct radio interface device required for the new radio.
Double-sided tape should be used for installation of the master station on glass. If the IM-900 is to be mounted on a window that has a sliding section it should be mounted on the fixed section at a location that will not restrict opening the window. A 10- foot power cord is supplied for connection to the power source.
the MACB and you will need to modify your microphone. Cut the connector off the hand microphone and install the supplied connector. A schematic to determine correct pin-outs is included with the MACB. Plug the hand microphone into the MACB and perform a radio check using both the hand microphone and headsets.
Note the position of a JS-900, JS-901, JS-902, PS-900 and the RSJ-900 stations in relationship to each other or to the IM-900 Master Station. Since some of these stations are may be daisy-chained, each must occupy its correct position in the chain for the system to work properly.
the cable is routed down from the enclosure and the enclosure is not mounted horizontally, see Figure 5.9. Mounting Exterior Stations Figure 5.9 5.9.1 Installation of Weatherproof Stations Installation of these watertight enclosures is facilitated by virtue of a self-adhesive back. To install these stations, temporarily position the station on a clean flat surface at the installation location.
hours are recommended for full strength of the adhesive to be achieved, however, the station is usable during this period. Mounting holes can be used in conjunction with or in place of the adhesive. 5.10 Cable Installation Insert the cables along existing grooves and ducts if possible. Where ducts or grooves are not available, select routing that will not interfere with normal operations of the crew.
If you want to check the intercom with the radio cable disconnected, you can clip a lead from the metal portion of the headset jack in the IM-900 to chassis ground. •Check the volume control knob setting.

IM-900. Disconnecting the radio cable will remove the grounding point from the system; simply grounding pin 4 of the “Radio” port on the IM-900 will allow a complete path. •If the whine stops or is greatly reduced, the FM radio is probably the source.

9RC cables: Replaced by RCB cables and the RIM-900-BAL Cable went from radio to an intercom station, the IM-900 for example. The new RCB cables go from the radio to a RIM-900-BAL, and the RIM-900-BAL goes to the intercom station. This allows for more control over receive and transmit volume levels.
