PRISM –Wireless HUD SystemInstallation & Operation InstructionsWireless HUD System ContentsPRISM (In-Mask Receiver) -4056743Installation of the In-Mask ReceiverRemove the nose cup from inside the mask. Install the In-Mask Receiver into the mask. Tilt the In-Mask Receiver toward the speech diaphragm and locate the left side (battery side) of In-Mask Receiver ring behind speech diaphragm ring (Figure 1a). Spread right side of the In-Mask Receiver ring only far enough to get it to snap into place around speech diaphragm ring (Figure 1b). CAUTION: Do not overflex the In-Mask Receiver ring legs during installation. Press top of In-Mask Receiver ring down to ensure it is fully seated (Figure 1c). Install the nose cup back into place making sure that the nose cup is fully seated behind the speech diaphragm mounting ring. (Figure 1d & 1e).WARNING: SUBSTITUTION OF COMPONENTS MAY IMPAIR INTRINSIC SAFETY.AVERTISSEMENT: LA SUBSTITUTION DE COMPOSANTS PEUT COMPROMETTRE LA SÉCURITÉ INTRINSÈQUEIntrinsically Safe.

To prevent ignition of a hazardous atmosphere, batteries must only be changed in an area known to be nonhazardous.AVERTISSEMENT! Afin de prevenir l’inflammation d’atmospheres dangereuses, ne changer les batteries que dans des emplacements designes non dangereux.This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.PRISM Transducer -4056744FIGURE 1a FIGURE 1bFIGURE 1c FIGURE 1dBattery installationIn-Mask ReceiverThe In-Mask Receiver is powered by one CR2 lithium battery. To install the battery, unscrew the battery cap using a coin (Figure 2a). Noting the battery polarity, install a new cell, positive ”+” end in first (Figure 2b). Screw battery cap securely into place. When a new battery is first installed, the In-Mask Receiver will blink the green low-battery indicator for 5 seconds to indicate that the battery has been installed correctly.Caution: The cell used in this device may present a fire or chemical burn hazard if mistreated. DO NOT recharge, disassemble, heat above 100oC, or incinerate.Dispose of used cell promptly. Keep away from children.TransducerThe Transducer is powered by two (2) CR2 lithium batteries. To install the batteries, unscrew the battery cap using a coin (Figure 3a). Noting the battery polarity, install two new cells, positive ”+” end in first (Figure 3b). Both batteries MUST be replaced with fresh cells at the same time.Screw battery cap securely into place.Caution: The cell used in this device may present a fire or chemical burn hazard if mistreated. DO NOT recharge, disassemble, heat above 100oC, or incinerate. Dispose of used cell promptly. Keep away from children.Note: Install batteries with transducer in transmission range of In-Mask Receiver.When new batteries are first installed, the In-Mask Receiver will blink the amber low-battery indicator for up to 5 seconds to indicate that the batteries have been installed correctly. Note: Use only Duracell or Energizer CR2 lithium batteries. FIGURE 3aFIGURE 3bFIGURE 2a FIGURE 2bFIGURE 1ePage 1 of 2
CleaningIn-Mask Receiver :Remove In-Mask Receiver from mask and use a damp cloth to clean the surface of the assembly. Refer to the mask cleaning procedure in the Draeger Service manual.Transducer: Use a damp cloth to clean the surface of assembly.Wireless HUD System OperationThe In-Mask Receiver is located inside the mask. It will power-up when it is in range of a transducer unit that is sensing air pressure. The transducer is located on the back plate and is connected to the high pressure line (Figure 4).When the In-Mask Receiver receives the first air pressure signal from the transducer, the display will initially be on for 20 seconds. After that the display will function as described below.You should be at least 6 Feet away from another PRISM system when first pressurizing your SCBA to prevent your In-Mask Receiver from linking to another system. If this occurs, move away from the other individual. Your In-Mask Receiver will display a Loss Of Signal indication in approximately 40 seconds then link to your own SCBA. A properly linked PRISM system will function correctly when used in close proximity to another properly linked system. In-Mask Receiver low-battery indicatorThe Green led will flash at a rate of approximately once per second.Transducer low-battery indicatorThe Amber led will flash at a rate of approximately once per second.Tank Pressure below ¼The Red led will blink at a rate of once per second until the tank is out of air.Tank Pressure between ¾ & ½3 leds (R,A,G) will be on for 12 seconds and then be off for 48 seconds.Tank pressure between ½ and ¼The Red led will be on for 24 seconds, while the Amber led will blink at a rate of once per second for 24 seconds. Both leds will then be off for 36 seconds. After that, both leds will be on for 12 seconds and then be off for 48 seconds.Tank Pressure above ¾All 4 leds (R,A,G,G) will be on for 12 seconds and then be off for 48 seconds.Low Battery Indication*When 2 hours or less of operation time remains the low battery indicators will function as follows:The Flashing LED will remain active until the battery is replaced or the system is shut down. WARNING: Inaccurate reading may occur if the battery has not been changed after 2 hours in the low battery condition.FIGURE 4Loss of Signal Indication (LOS)When the In-Mask Receiver is out of range or does not receive a transmissionfrom the transducer the 4 pressure leds will scan red-amber-green-green 5 times. If the In-Mask Receiver is brought back into range of the transducer and there is still tank pressure, the In-Mask Receiver will resume displaying the proper tank pressure indications. Power DownWhen the SCBA system has been depressurized or is out of air, the In-Mask Receiver will receive a power down signal, the 4 pressure leds will flash 5 times at a rate of approximately once per second and then turn off.If the In-Mask Receiver has not received a signal for approximately 4 minutes, the In-Mask Receiver will shut down. In this case, the 4 pressure LEDs will flash 5 times at a rate of approximately once per second and turn off. The In-Mask Receiver will activate again if a valid signal is received.P/N 4056858 Rev. 0 Low Battery ShutdownWhen the batteries are insufficient to insure that accurate data is being displayed, the system will shut down. In this case, the 4 pressure LEDS will flash 5 times at a rate of approximately once per second. At this point the batteries must be replaced.* The Low battery indication may prematurely activate at temperatures below 0oF (–18oC) The Flashing LED will remain active until the system is shut down and re-pressurized at higher temperatures.•REFER TO YOUR SECONDARY GAUGE FOR STATUSTroubleshootingNo user serviceable parts inside.WARNING: SUBSTITUTION OF COMPONENTS MAY IMPAIR INTRINSIC SAFETY.AVERTISSEMENT: LA SUBSTITUTION DE COMPOSANTS PEUT COMPROMETTRE LA SÉCURITÉ INTRINSÈQUENo new battery indication:•Check battery orientation as indicated on unit.•Verify that batteries are in good condition.•Verify that the battery cover is securely tightened.No pressure indication:•Check batteries in system.•Is SCBA pressurized above 250PSI?System shuts down while in use:•Check batteries in system (see Low Battery Shutdown).•Refer to your secondary gauge for status.Loss Of Signal indications:•Check batteries in system.•Check In-Mask Receiver and transmitter for damage.•In-Mask Receiver was linked to another individual.Your In-Mask Receiver appears to be linked to another individual:•This may have occurred during power up if you were close to anotheractive system.•Move approximately 6 feet away from others.•Refer to your secondary gauge for status until the In-Mask Receiver links to your SCBA. This will occur within 10 seconds after the LOS indication.LED display appears to not change intensity:•Clean and dry the lens on the In-Mask Receiver with a soft damp cloth.•Move to a brightly lit area.•Link the In-Mask Receiver to a fully charged SCBA.•Cover and uncover the lens with your finger while the 4 LEDs are on. You should notice the LED intensity change.DimmingThe In-Mask Receiver is equipped with an automatic dimming feature to allow the display to be visible in bright ambient light while not being distracting under dim light conditions. The sensor is fastened under a lens located on the top of the receiver. The 4 LEDs of the pressure display will be at their full brightness in bright light. They will dim when entering a dark area. Keep this area clean to allow proper function.LensDraeger Safety, Inc.101 Technology DrivePittsburgh, PA 15275-1057USAPhone: 800-922-5518Fax: 800-922-5519Page 2 of 2
