Study for the In-Building Public Safety Communications (IB-PSC) certification and carry your RF field tools in one offline app — built for the technicians who install, test, and design ERCES systems, also known as ERRCS.
★ 200 exam-style questions across 8 categories: RF fundamentals, components and equipment, codes and standards, survey and design, installation, testing and maintenance, FCC and regulatory, and safety and project management
★ Full-length timed exam simulations matched to the real computer-based test formats — Level I (88 questions / 110 min), Level II (143 / 155), Level III (126 / 170), and Design (110 / 150)
★ Open Book mode, mirroring the real exam's approved-reference policy
★ Field reference: coverage requirements under IFC 510 and NFPA 1225, the DAQ scale, monitored conditions, public safety frequency bands, grid testing steps, and formulas
★ Field tools that work offline on the jobsite:
• dBm to watts, both directions
• VSWR and return loss
• Link budget / EIRP with margin against your target
• Coax run loss for LMR-400, 1/2 in and 7/8 in at 150, 450 and 800 MHz
• Cascade calculator for gains and losses
• Isolation margin against booster gain
• Battery runtime against the 12-hour requirement
• 20-grid floor test tracker with pass/fail verdict logic
★ Instant feedback with an explanation and code reference on every question
★ Track your best score by category and by certification track
★ 100% offline. No account, no sign-in, no internet required.
BUILT FOR THE WORK, NOT JUST THE TEST
Whether your AHJ calls it ERCES or ERRCS, this covers the material you live in: bi-directional amplifiers (Class A and Class B), distributed antenna systems, donor antennas and isolation, UL 2524 listing, NFPA 72 supervision, the -95 dBm benchmark, DAQ 3.0, 12-hour battery backup, grid acceptance testing, 2-hour pathway survivability, and FCC Part 90.219 licensee consent.
WHO IT'S FOR
Low-voltage and fire alarm technicians, RF and DAS installers, public safety communications techs, system designers, and inspectors preparing for certification — or anyone who needs the numbers on a jobsite without a signal.
FREE, WITH AN OPTIONAL UPGRADE
Every question, simulation, lesson, and tool is free. A single one-time purchase removes ads. No subscription, and nothing is locked behind a paywall.
