located on the mask-mounted regulator.

Console

• The console shall be located on the user’s right shoulder harness.

• The control console shall come with a mechanical (analog) pressure gauge that is angled at 30°.

• The console shall contain an integral, edge-lit, mechanical pressure gauge that is automatically turned on by opening the cylinder

valve.

• The console shall display to the user the following:

- Pre-Alarm: alternating red ashing LED’s;

- Full Alarm: dual ashing red LED’s and a ashing PASS icon;

- Low Battery: red ashing LED’s;

- Normal System Operation: ashing green LED.

• The console shall also include icons to indicate:

- Range status

- Evacuation

- Withdraw (self-evacuation)

- Electronic Personnel Accountability Report (ePAR)

- When the system is ready to receive the user’s ID through an RFID card

• The console shall contain a photo sensing diode that automatically adjusts the brightness of the HUD as the ambient lighting
conditions change.

• The console shall contain an integrated RFID tag.

• The console shall contain push buttons for user interface.

• The push buttons shall be designed to minimize accidental activation.

• A yellow color-coded push button shall permit system reset.

• A red color-coded push button shall permit manual activation of the full alarm mode.

• A gray color-coded push button shall permit the activation of the withdraw mode.

• The console shall be equipped with a LED “External HUD” allowing others to determine the user’s cylinder pressure through the

same color-code scheme as the HUD display on the mask-mounted regulator.

• A green LED shall be illuminated across the gauge face to indicate a cylinder with greater than half cylinder pressure.

• A yellow LED shall be illuminated across the gauge face to indicate a cylinder with less than half cylinder pressure.

• A red LED shall be illuminated across the gauge face to indicate a cylinder with less than 35% of the rated cylinder pressure.

Sensor Module

• The system shall include a sensor module mounted to the SCBA backframe and located in an area between the cylinder and
backframe in a manner designed to protect the assembly from damage.

• The sensor module shall contain a motion sensor that is sensitive to user hip movement to reduce false activations.

• The sensor module shall contain redundant, dual sound emitters for the audible alarm and dual visual “buddy” indicator lights.

• The sensor module sound emitters shall be oriented in multi-directions for optimal sound projection.

• The sensor module sound emitters shall broadcast a unique alarm tone for the following conditions:

- Pre-alarm PASS

- Full-alarm PASS

- Electronic Personnel Accountability Report (ePAR)

- EVAC

- System Integrity

- Low battery

• The visual indicators on the backframe mounted sensor module shall ash green during normal operation.

• The visual indicators shall ash red when the device is in pre-alarm and full-alarm.

• The visual indicators shall ash orange when the SCBA has reached one-half cylinder pressure.

• The visual indicators shall ash a combination of red, green, and white when the SCBA has reached 35% of the rated cylinder

pressure.

• The sensor module shall have a Bluetooth chipset integral to the unit to provide wireless connectivity to external devices.

Integrated Self-Rescue Belt

• The optional integrated self-rescue belt shall be compliant to the NFPA 1981, 2018 edition and NFPA 1983, 2017 edition
standards.

• The waist belt shall be available in one size, and adjustable to t waist sizes 28” to 50”.

• The waist belt shall be constructed of Kevlar® aramid bers.

• The waist belt shall have dual adjustment points to allow the belt to remain centered while donning.

• The waist belt shall utilize side thumb-release buckles for ease of dong.

• The waist belt shall incorporate an optional quick release feature to jettison the SCBA.

• The waist belt shall utilize the patented COBRA buckle system.

• The waist belt shall include a D-ring integrated into the front buckle that can be utilized as an NFPA 1983 rated attachment or

positioning point.

• The assembly shall consist of the following components: waist belt, life safety rope, fall descent device and anchor connector.

• The life safety rope shall be Tsafe 7.5mm escape rope utilizing a Technora sheath and nylon core construction.

• The descent device shall be an auto-locking Sterling Rope F4 Descender Escape Device with single brake.

• The system shall have an option for either an aluminum Lightning GT hook or a steel Crosby hook.

• The complete system shall have a minimum tensile strength of at least 13.5 kN (3034 lbf) without failure.

Electronic Voice Communications

• The respirator, when congured with the AV-3000 HT facepiece, shall have an optional facepiece-mounted voice amplication
device to electronically project the user’s voice.

Refer to EPIC 3 Voice Amplier Bid Specications, H/S 7093

• The respirator, when congured with the AV-3000 HT facepiece, shall have an optional facepiece-mounted radio interface
communication system that provides voice amplication and wireless communication with two-way radios.

Refer to EPIC 3 RI Voice Communication System Bid Specications, H/S 7489

• The respirator, when congured with the AV-3000 HT facepiece, shall have an optional facepiece-mounted radio direct
interface communication system that provides voice amplication and wireless communication with two-way radios.

Refer to EPIC 3 RDI Voice Communication System Bid Specications, H/S 7570

In-Mask Thermal Imager

• The respirator, when congured with the AV-3000 HT facepiece, shall have an optional hands-free, in-mask thermal imager.

• The in-mask thermal imager shall consist of a facepiece-mounted thermal imaging camera and an in-mask display.
