Yearly: check and test every manual call point; inspect other warning devices; test panel controls and keypads and every visual indicator and display; measure standby and full alarm current per Appendix F, work out the capacity needed and confirm the installed nominal capacity is at least that; test detectors per Appendix G with correct zone indication (100% of detectors yearly where they serve special hazard systems); test audibility in all areas (a reduced-level alternative signal is acceptable) or, with a sound system or EWIS, test per Table 6.4.3.2; measure the sound pressure level at a reference point per amplifier against the required level; test at least 20% of alarm acknowledgement facilities so all are tested over 5 years; test any enabled alarm investigation facility; discharge test batteries not replaced in the previous two years; smoke and heat alarms per Clause 6.4.2; report items past or about to pass a defined service life; survey all areas from floor level for alteration or damage, suitability of devices for current use, nuisance alarm or unwanted discharge risks, cabling and labelling, and secure mounting of CIE components; and simulate alarms to prove each interface transmission path. Smoke hazard management systems additionally: fire fan control panel stays in fire mode until reset at the panel, manual ON-AUTO-OFF overrides work, and airflow, open-circuit, closed-circuit, phase-fail, fan-running, fan-stopped and fan-fault indicators operate. Special hazard systems additionally: test each monitored status function, simulate operation of electrical directional valves, test and record the discharge time delay, and prove agent release indication at the FIP.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
