Cockpit

Annunciator and Aural Warning

In the cockpit, safety and early detection of possible problems are crucial. Our company began by offering innovative cockpit solutions, and it is an area in which we continue to excel. Today, Heads Up offers Caution Warning Systems (CWS) and Aural Warning Systems (AWS) to fit specific OEM or system integrator requirements.

CWS100

This low-cost caution/warning panel with LED display features legends and colors that can be configured to meet your requirements. Eight inputs with active-ground logic provide warning, caution and advisory information to the flight crew. Sunlight-readable long-life LED display features low power consumption and cool operation. (Certification/Compliance: 14 CFR Part 21, RTCA/DO-160C)

CWS200

This unit provides digital voice/tone warnings to the flight crew while controlling audio mixing levels of up to 8 audio inputs. The two independent audio outputs automatically adjust their volume, based on information obtained from the air data computers via ARINC 429 interface. It is field programmable using a laptop computer w/RS-232. (Certification/Compliance: 14 CFR Part 21, RTCA-DO-160D, RTCA/DO-178B, Level C)

CWS300

This redundant, high-performance digital caution/warning unit integrates visual and audio messaging, and monitors up to 112 discrete aircraft inputs to provide warning, caution and advisory information. High-output LED technology illumination offers exceptional readability under all ambient lighting conditions, yet provides very cool operation. This unit is ideal for mounting in glare shields or other direct sunlight locations, and display colors and legends can be modified for custom applications. Parametric programming controls input trigger levels, logic levels, debounce times, associated visual and audio messages, master caution/master warning triggers, and much more. Complex logic capabilities and multiple processors reduce nuisance warnings while enhancing reliability. The RS-232 interface allows for remote diagnostics without removal. (Certification/Compliance: 14 CFR Part 23, RTCA/DO-160D Changes 1, 2 and 3, RTCA/DO-178B, Level C)

CWS425

This chassis-mounted annunciator is a solid-state, 72-channel caution/warning panel with LED display that is excellent for low-standby current applications. Seventy-two inputs with active-ground logic are monitored to provide warning, caution and advisory information. Sunlight-readable long-life LED display provides for low power consumption and cool operation. Display legends and colors can be configured to meet customer requirements. Digital tone/voice generators, 429 interfaces and complex logic modules are optional. (Certification/Compliance:14 CFR Part 21, RTCA/DO-160D)

CWS525

This high-performance digital caution/warning unit integrates visual and audio messaging, monitoring up to 76 discrete aircraft inputs and providing warning, caution and advisory information. The high-contrast 56-element LCD display incorporates unique LED backlighting for exceptional readability under all ambient light conditions. Ideal for mounting in glare shield or other direct sunlight locations within the cockpit. Display colors and legends can be modified for custom applications. Parametric programming controls input trigger levels, logic levels, debounce times, associated visual and audio messages, master caution/master warning triggers, and much more. Complex logic capabilities and multiple processors reduce nuisance warnings while enhancing reliability. RS-232 interface allows for remote diagnostics without removal. (Certification/Compliance: 14 CFR Part 21, RTCA/DO-160C, RTCA/DO-178A, essential criticality)
