33 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Acceptance test purpose
- Verifies that a newly installed or modified fire alarm system complies with its design, is installed per the plans, and functions as intended before being placed into service.
- Record of completion
- A document completed at installation and updated at acceptance testing that lists system features, device counts, and signatures of the installer and the authority accepting the system.
- Smoke detector sensitivity range
- Listed smoke detectors typically must respond within 0.5 to 4.0 percent per foot obscuration; readings outside this range require cleaning, recalibration, or replacement followed by retest.
- Smoke entry test
- Testing that introduces aerosol or listed test smoke into the detector chamber to verify alarm response; magnet or jumper tests only verify wiring and are not substitutes for smoke entry testing.
- Heat detector test method
- Applying a listed heat source or manufacturer-approved method at the installed detector to confirm it operates at its rated temperature and before reaching its maximum listing threshold.
- Audibility requirement
- Alarm sound must exceed average ambient by at least 15 dBA, or exceed maximum ambient by 5 dBA, whichever is greater, measured at the required locations.
- Sleeping area sound level
- In sleeping areas, the alarm must produce at least 75 dBA at the pillow level, or 15 dBA above ambient, and low-frequency 520 Hz sounders are required where adopted.
- Intelligibility testing
- Verification that voice messages are understandable at occupied locations, typically measured using speech transmission index or common intelligibility scale methods per the design.
- Standby battery duration
- Secondary batteries must support 24 hours of standby followed by 5 minutes of alarm load, or 4 minutes for emergency voice alarm systems, unless a longer time is required.
- Battery load test
- Discharging the battery under a measured load to confirm it delivers at least 80 percent of rated capacity; batteries failing this criterion must be replaced and the calculation rechecked.
- Annual testing interval
- Most initiating devices, notification appliances, and control units must be inspected or tested at least annually, with the results documented on the inspection and testing form.
- Semiannual supervising station test
- Supervising station and remote station functions, including signal transmission and processing, must be tested at least semiannually to confirm correct reporting to the off-site location.
- Quarterly battery inspection
- Batteries are inspected quarterly for corrosion, terminal tightness, electrolyte level where applicable, and charging voltage, with results recorded on the inspection form.
- Ground fault test
- Introducing a controlled ground fault on a circuit to confirm the control unit annunciates the trouble condition and identifies the affected circuit.
- Open circuit test
- Opening an initiating device circuit or notification appliance circuit to verify the control unit reports a trouble condition within the required time.
- Cross-zone logic test
- Verifying that a releasing or suppression system activates only after the required combination of detectors operates, with the correct time delay and sequence.
- Abort switch test
- Confirming that activating the abort switch during the release countdown halts discharge and that the abort function resets properly after the event.
- Notification appliance circuit voltage
- Measured voltage at the end of the circuit must meet the appliance listing and manufacturer tolerance under alarm load, confirming wiring loss is within design limits.
- Inspection versus testing
- Inspection is a visual check of condition and installation; testing is the functional operation of a device or system to confirm performance against its listing and design.
- Test plan contents
- A written test plan identifies devices to be tested, test methods, sequence, personnel, and documentation requirements, and is reviewed before testing begins.
- Detector cleaning interval
- Smoke detectors are cleaned per manufacturer instructions when sensitivity testing shows drift or when the environment warrants; cleaning is followed by sensitivity retest.
- Duct smoke detector test
- Testing by introducing smoke or listed aerosol into the duct sampling tubes and confirming detector alarm and correct supervisory fan shutdown response.
- Waterflow switch test
- Operating the inspector's test valve or bypass to simulate flow and confirming alarm initiation within the required time, typically 90 seconds or less.
- Valve tamper switch test
- Partially closing a supervised control valve to confirm the tamper switch reports a supervisory signal to the control unit and identifies the valve.
- Supervisory signal test
- Verifying that off-normal conditions such as valve closure, low air pressure, or power loss annunciate as supervisory signals distinct from alarm and trouble signals.
- Trouble signal response time
- The control unit must annunciate a trouble condition within 200 seconds of the fault occurring, and the trouble must be recorded and displayed.
- Alarm signal response time
- The control unit must process and annunciate an alarm signal within 10 seconds of receipt from a detector or initiating device, unless otherwise listed.
- Remote annunciator test
- Confirming that each remote annunciator displays alarm, supervisory, and trouble conditions correctly and that its controls function as intended.
- Reacceptance test
- Testing required after system modification, repair, or addition; it covers affected components plus verification that the overall system still operates as designed.
- Documentation retention
- Inspection, testing, and maintenance records must be retained and made available to the authority having jurisdiction for a period specified by code or local requirement.
- Impedance measurement
- Measuring circuit resistance or impedance to verify wiring is within design limits and that notification appliances receive adequate voltage under worst-case alarm load.
- Visual inspection scope
- Checking device mounting, labeling, accessibility, damage, contamination, and proper installation location without operating the device; deficiencies are logged for correction.
- Test record signatures
- Inspection and testing forms must be signed by the person performing the work and by a representative of the owner, with dates and results recorded for each device.
