HEARING PROTECTION: Now you can protect your hearing and have clear communications with all personnel. Crew member's hearing is protected by using Sigtronics' headsets. They are light-weight for comfort, reduce noise for your safety, and have noise-canceling, electret microphones for superb voice fidelity.

RADIO INTERFACE: The intercom systems interface to all mobile radios, allowing communications (both transmit and receive) to be heard through each headset. Radio transmitting can be done from two or more positions. The crews' intercommunication is not transmitted over the radio. To transmit over the radio, the radio push-to-talk switch must be activated, and only that person's voice will be heard over the air.

• The noise-canceling electret microphone assures crystal clear voice communications.
• The microphone "ultra-foam" windscreen stops wind, dust and moisture from affecting microphone performance.
• All Sigtronics headsets are RFI and EMI free electronics.
• 24 dB noise reduction for compliance with NFPA 1500.
• Headset frames are made of hardened spring steel for durability.
• Cables have super-tough, insert-molded plugs. Nickel coated brass plugs prevent loss of communication due to corrosion.
• "Stop-Break" cables are made of 105 strand (per conductor), high flex, high endurance, flame proof, polyurethane coated wire.

Our SE-2 & SE-8 Series headsets feature soft headbands designed to be worn under helmets.With microphone booms that rotate 180 degrees for use on either side of the head, our SE-2 / SE-8 Series headsets offer the perfect combination of comfort, performance, and flexibility.
WARRANTY: One year parts and labor.

• Easy grab volume controls adjust for your listening comfort
• Self-adjusting and lightweight ear cups assure you a comfortable fit
• Headsets are lightweight for your comfort
• Receiver elements are not affected by temperature or humidity

Made with the same attention to durability and performance as the headsets for helmet use, the SE-18, SE-40 and SE-48 headsets have full headband pads for use without helmets. Available in dual or single ear cup models, with flex or full swivel mic booms, in a wide selection of standard production configurations.
Warranty: One year parts and labor.

• Voice Activated—Turn on instantly when you start speaking and turn off when you stop, which eliminates constant noise pick-up through the headset microphone.
• Interfaces to single or dual mobile radios, allowing all communications, both transmit and receive, to be heard through each headset.
• Compatible with cellular telephones.
• Radio transmit is accomplished by way of the headset microphone through use of a push-to-talk switch. This design allows placement of the push-to-talk switch in the most accessible location and eliminates the need to reach for the hand microphone.
• As an added safety feature, the intercom function is automatically disabled while transmitting so that only the voice of the person transmitting goes over the air, however his voice is heard by all crew members.

FAILSAFE: The mobile radio, hand microphone and speaker will function normally with the intercom installed.The transmit keying circuit is fully isolated to provide for all radio keying configurations.

SIMPLE INSTALLATION: The UltraSound is small and light weight and mounts above or below the panel and adjusts for easy viewing.The intercom package comes with all the neces-sary mounting hardware for installation in the apparatus.

Small rugged mounting boxes, (1-5/16"x2"x2") are provided with every unit to accommodate headset jacks and push-to-talk switches. All systems include jack with splash cover for the pump panel. Complete and easy to follow instructions are provided along with helpful hints, operating instructions, and a toll free 800 number for technical help.

VERSATILITY: Systems are available for all fire apparatus and emergency vehicles: such as 4 crew -5 station, 6 crew -7 sta-tion or 12 crew -13 station intercoms. The extra station can be installed where needed (i.e. pump panel, bucket, turret.)

RADIO OPERATION: Models US-45S, US-67S and US-12S are for single radio operation. Models US-45D, US-67D and US-12D are configured for dual radio operation.They have additional switches that allow you to select which radio to transmit and receive on.

STATIONS:The US-45S and US-45D intercoms will accept up to four headsets.Two positions will have radio transmit capability. The US-67S and US-67D will accept up to six headsets. Three positions will have radio transmit capability.The US-12S and US-12D will accept up to twelve headsets. Four positions have radio transmit capability. Radio transmit at the pump panel is included in all the above systems.

Extra headsets can be paralleled where crew members operate from more than one position. Additional positions may be added at platform (turntable), ladder tip (bucket) or tailboard.

Communicate On 2 Radios At The Same Time And Monitor A Third Radio!

DUAL RADIO CAPABILITY: You and a crew member can communicate with two agencies at the same time and have intercom capability with two more crew members. The dual radio capability of the S-A-F-E unit allows the two command headset positions to select which radios to transmit and receive on, independent of the other headset. Each headset position has dual volume controls; one for your radio reception, and the other for your intercom volume level. The third and fourth headset positions are slaved to the right side of the unit and will hear whichever radio the right side has selected.

AUXILIARY INPUT: You can also selectively monitor a third radio via the auxiliary input.

TECHNICAL HIGHLIGHTS:

• Excellent RF immunity guarantees clean, clear, radio communications.
• Automatic Sidetone Generation allows everyone in the vehicle to hear both sides of the radio conversation.
• Uses Sigtronics' noise attenuating, single plug headsets.
• The unit can be mounted above or below the panel and will adjust to various angles for easy viewing.
• Quick Disconnect feature gives it flexibility and makes it interchangeable.
• Standard Equipment includes:4 headset jacks and mounting boxes. 2 push-to-talk (PTT) switches. 4 foot interface cable, 1 roll of hook up wire. Installation and Operating instructions.

OPTIONAL: Dual S-A-F-E Communicator (Remote Head)

The Dual S-A-F-E Communicator is similar to the unit described above except there are two identical boxes (one becomes a remote head to be mounted somewhere other than in the driver's area). It allows four crew members to transmit on two radios and up to eight people have voice activated intercom capability. Ideal for use in command vans.

• Equipment provided is the same as regular S-A-F-E except there are four PTT switches and 8 headset jacks and mount­ing boxes.
