Flat Earth Pro vs Fire Alarm System Simulator

Flat Earth app is a tool used to visualise daylight coverage, sun and moon overhead positions, rise and set times, moon phases, lunar parallactic angle and liberations, and much more in a simple and easy to read Azimuthal projection of the earth. Once you start the application, you will be informed immediately about the current zenith (overhead) position of the sun and moon, the current phase and parallactic angle of the moon, day and night map and much more relative to any observer position on earth. With one touch you can rotate clockwise or counter-clockwise to move time to the future or to the past and visualise the orbital motion of Sun, Moon, and 5 more optional celestial bodies realtime and with great accuracy. All of the core features of the app work offline including time zones. The graphical positions of the celestial bodies on the map represent the zenith (overhead) position relative to the app time. The direction of the celestial body (azimuth) in your local sky and its altitude can be visualised as well as the sky dome relative to any location through the navigation tab. The Flat Earth Application includes: - Lunar Perigee and Apogee in realtime as well as event schedule. - Lunar Phases in realtime as well as event schedule. - Local and regular Compass, and directions for the current sky position for all of the available celestial bodies. - Altitude , azimuth and current zenith position are featured and easily accessible for every feature celestial body. - Day light coverage visualisation over the earth for any particular time instant. - The rise and set times for any location on earth for all the of the available celestial bodies. - All time zones. - Moon libration and Orientation at any date and time and at any location. - Unique local weather forecast integrated within the app in app time controller. - Unlimited Moon, Sun and Earth Data at ANY date and time. - The ability to take and share a high resolution shot of the earth a moon. - Custom Notification at any date and time.

Fire Alarm Studio is a comprehensive training and reference app built for fire alarm technicians, NICET certification candidates, and fire protection engineers. Version 2.0 adds two major new features specifically designed for professional development and field use. NEW — NICET EXAM PREP Practice for your NICET Fire Alarm Systems certification with 60 questions written to the NICET Level I and Level II competency framework. Questions span six core areas: Fire Science, Detection Systems, Signaling Systems, Control Panels, Codes and Standards, and Testing and Inspection. Choose Quick Practice (20 random questions), Full Exam (60 questions with a 90-minute countdown timer), or drill by topic. Every question includes a detailed explanation with the relevant NFPA 72 code reference. Your score history is saved automatically so you can track progress over time. NEW — FIELD CALCULATORS Four real-time engineering calculators built for on-site use. NAC Voltage Drop calculates end-of-line voltage and flags NFPA 72 Section 10.14.1 compliance. Battery Capacity Sizing applies the required 20 percent derating per Section 10.6.7 and recommends the correct battery size. Detector Spacing determines the number of smoke or heat detectors required for a room based on ceiling height and NFPA 72 Table 17.6.3 limits. Wire Gauge Selection shows voltage drop and pass/fail status for all common AWG sizes simultaneously. Every calculator displays the governing NFPA 72 code section alongside the result. ILLUSTRATED GALLERY — 63 DIAGRAMS Browse 63 professional fire alarm system diagrams across eight categories: System Architecture, Wiring Topologies, Device Types, Control Panels, Code and Standards, Installation Details, Testing Procedures, and Signal Flow. Pinch to zoom up to 6x and swipe between illustrations. A thumbnail strip lets you jump directly to any diagram. STRUCTURED CURRICULUM Eight learning modules covering fire science fundamentals, detection technology, initiating devices, notification appliances, control panels, suppression interfaces, high-rise systems, and mass notification. Each module includes multiple lessons with explanations, diagrams, and key takeaways. INTERACTIVE LAB SIMULATIONS Practice reading initiating device circuits, understanding Class A and Class B wiring, and tracing alarm signal flow through a panel without being on a live system. GUIDED PROJECTS Step-by-step field projects including basic system installation, detector placement verification, battery load calculations, and pull station testing procedures. QUICK REFERENCE LIBRARY Searchable tables for NFPA 72 detector spacing, battery sizing, conductor requirements, and alarm notification thresholds. Formatted for fast lookup in the field. INSTALLATION GUIDE A complete walkthrough of the inspection and testing workflow from pre-installation checks through final acceptance testing, organized by NFPA 72 chapter. USE CASES Real-world fire alarm system scenarios for high-rise, commercial, educational, healthcare, and industrial occupancies.
