SAFETY INFORMATION Intrinsic Safety and Certification What is Intrinsic Safety? Intrinsic safety is a type of protection in which a portion of the electrical system (apparatus, circuits, and wiring) contains only equipment that is incapable of causing ignition in the surrounding atmosphere. No single device or wiring is intrinsically safe by itself (except for battery operated, self-contained apparatus such as portable pagers, transceivers, gas detectors, etc., which are specifically designed as intrinsically safe, self-contained devices). Devices are intrinsically safe only when employed in a properly designed intrinsically safe system. Certification The Firecom 4100 Portable Intercom System is listed by SGS / United States Testing Company (USTC) as Intrinsically Safe for use in certain hazardous atmospheres. Hazardous atmospheres can range from gas vapor to dust to flying fibers. The listing by USTC indicates that Firecom’s 4100 Portable Intercom System has undergone a series of tests that demonstrate it is incapable of releasing a level of energy, either thermal or electrical, under normal or abnormal conditions, that may cause ignition in a specific hazardous atmosphere. The Firecom 4100 Portable Intercom System has been listed as Intrinsically Safe for use in Class I, II, and III, Division 1, Groups A, B, C, D, E, F, G hazardous locations. The following accessories can be used with the Firecom 4100 Portable Intercom System while maintaining full compliance with the Intrinsically Safe listing: Headset

CONFINED SPACE Definition A confined space has all of the following characteristics: • A restricted opening that makes entry and exit difficult • Large enough for an adult to enter completely • Not designed to be occupied Most confined spaces are designed to hold substances such as liquids, gases, and loose materials, or to house equipment. Though they come in many sizes and shapes, most can be classified in two ways: those with depth and open tops, and those with narrow openings. Examples Open top and deep spaces include pits, wells, vats, hoppers, bins, degreasers, and kettles. Spaces with narrow openings include ship compartments, silos, pipes, tunnels, utility vaults, casings, and sewers. Permit Space A permit space is a confined space that may contain life-threatening hazards. No one can enter a permit space without first completing a written entry permit and having it signed and posted by an entry supervisor. For more information, see the OSHA web site. For a quick reference to the required Confined Space Standard permit, see www.orosha.org -or- osha.org

Firecom’s 4100 Portable Intercom System features six independent, full-duplex audio channels designed for continuous hands-free voice communications in confined space and high-noise environments. The six stations include four entrants, an attendant, and an additional monitoring station or accessory port. The system provides constant, real-time communications between all interfaced personnel. Each entrant is equipped with an individual alarm and local volume on each headset. In addition, each team has its own volume control at the main unit while the standby team has a built-in mute switch, that when pressed, prevents them from being heard by the entry team, attendant, and accessory ports. 4
SETUP AND CONNECTIONS Charging the Battery Figure 3.
Ground Connection
The Firecom 4100 Portable Intercom System is powered by a sealed lead-acid rechargeable battery housed in the base unit. Before you can put the 4100 Portable Intercom System to work, you must charge the battery with a full charge. Connect the battery charger to the back of the main unit and plug the battery charger into an indoor 120-volt AC outlet as shown in figure 3. Initial battery charge time is 24 hours. After the initial battery charge, charge time will decrease according to usage. The battery charger unit comes with an indicator light. The light will illuminate red if a fault condition exists, yellow when the unit is charging, and green when the charger is in float (slow charge) mode. The 4100 Portable Intercom System will operate up to 80 hours on a full charge. Do not drain the battery completely. Warning Battery chargers sold with this unit are not Intrinsically Safe. Warning Do not charge or change batteries in intrinsically safe zones or hazardous environments. Warning Use the battery charger indoors only. Ground Connection A grounding connection is provided on the back of the intercom unit (see figure 3). The intercom unit should be grounded according to local safety practices and those outlined by the National Electric Code. 5
SETUP AND CONNECTIONS The Intercom Case Figure 4.
Pressure Release Valve
The intercom base unit and accessories case are durable, watertight, and airtight with integrated pressure release valves. To open the base unit or accessory case, press the black button in the middle of the latch and lift as shown in figure 4. If the case does not open, the pressure release valve may need to be temporarily opened. This should equalize pressure and allow the case to be opened. After opening, return the pressure release valve to a closed position to protect internal components. Note: When the intercom lid is closed, the system automatically switches off. Connecting Headsets The 4100 Portable Intercom System headset includes heavy-duty cables with locking connectors and alignment features to assure correct wiring. To connect a headset to a cable, visually inspect both connectors for a notch in the female connector and a mating protrusion in the male connector. Align these items, retract the locking ring on the female connector, and insert. After insertion, push the locking ring forward and rotate clockwise to lock, as shown in figure 5. To disconnect cables, reverse the process. The identical process is used for connecting two or more cables together To connect cables to the intercom, remove the connector port covers on the intercom and repeat the process above, as shown in figure 6. See headset manuals, included with each headset purchased, for individual headset adjustments and setup.

OPERATION AND SYSTEM TEST Once the unit has been charged and the headsets connected, you are ready for operation. Put headsets on and adjust for good performance and a comfortable fit as indicated in your headset manual. Follow the steps below for clear hands-free communication between all persons wearing a headset. Step 1. Power On The 4100 Portable Intercom System is battery powered. To operate, activate the power switch located on the front panel (figure 2). The power light indicator on the front panel should illuminate. If the low battery light illuminates, the battery will need to be charged. See Charging the Battery in this manual. The intercom will automatically turn off when the case is closed. Note: The unit must be fully charged before first use. See Charging the Battery in this manual. Step 2. Volume Controls Portable Intercom headsets come with individual volume controls for each user. In addition, there are volume controls for each entrant team and the attendant on the main unit (see figure 2). To adjust the volume, turn the control knob clockwise to increase volume and counter clockwise to decrease. Step 3. Identification Area An erasable identification area is provided for each of the (4) entrants, seen in figure 2. A grease marking pencil is used for writing in these spaces and can be found on the interior lid of the intercom case (see figure 1). Examples of notes include entrant’s name and time of entry. Note: Use a clean dry rag or mild soap and water to erase identification areas. Step 4. Alarm Buttons Each Firecom Portable Intercom headset comes with an alarm button. If a headset is plugged into one of the (4) entrant headset ports and the headset alarm button is depressed, a warning light will illuminate on the front panel indicating which entrant has activated their alarm and an audible buzzer will sound (reference figure 2). The alarm is cancelled by depressing the alarm reset button on the front panel. Note: The accessory and attendant ports do not have alarm function capabilities. Step 5. Mute Button The mute button should be checked at the start of operation. When the mute button is depressed, the standby team will not be heard by other participants or on their own headsets. However, the standby team will hear communications between all other participants. The mute button will illuminate when activated. To deactivate the mute feature, depress the mute button (see figure 2).

Step 6. System Test Headset users should take turns speaking and listening as a group to make sure communication is open between all participants. If one or more participants can not be heard or hear, adjust volumes, check the mute button, or refer to the Troubleshooting in this manual. The alarm circuit and each entrant’s alarm should be tested prior to every use. Test the alarm circuit by depressing the alarm test button on the front panel. Turn the alarm off by pressing the alarm reset button on the front panel. Next, each entrant should test their individual alarm buttons located on each headset, one at a time. Both the audible alarm and entrant’s alarm indicator light should activate. This should be confirmed by the attendant. Turn off the alarm by pressing the alarm reset button and repeat the procedure for each entrant. Note: The accessory and attendant ports do not have alarm function capabilities.
