Guide resource
Power Supplies Batteries explains a decision that can materially affect security, safety and administration. Use it to prepare for a site assessment, then have the final design checked against the building, door and operational requirements.
Build a load schedule instead of choosing by label
List every lock, controller, reader, relay and auxiliary powered by the supply. Record normal, peak and simultaneous current, cable length and voltage requirement at the device. Electromagnetic locks may be continuous loads; strikes can have different activation characteristics; controllers and communications equipment add their own demand.
Set a backup objective and calculate for it
Define which doors and functions must continue, for how long, and what should happen as the battery approaches its limit. Battery capacity on a carton does not equal delivered runtime after ageing, temperature, conversion losses and required end voltage are considered.
Where loss of mains must release certain locks, battery backup can change the expected behaviour. Document the intended cause and effect for each opening.
Make faults containable and serviceable
Use appropriately protected distribution, identify each circuit and keep power equipment in a secure, ventilated and accessible location. A fault on one field cable should not unnecessarily remove unrelated doors. Supervise mains, charger and battery conditions where the chosen system supports useful reporting.
Test under load and plan replacement
Measure device voltage at realistic load, simulate mains failure, verify fault reporting and confirm recovery after power returns. Record battery chemistry, capacity, installation date and test result. Investigate swelling, heat, leakage or repeated low-battery events promptly; do not treat alarm silencing as repair.
Give the customer a usable power record
The handover schedule should show which supply feeds each controller and lock, protective-device references, battery details, monitored faults and the expected service response. Labelled equipment and an accurate circuit record reduce the temptation to disconnect unrelated doors during fault finding and help the customer plan battery testing and replacement before capacity is lost.
Power Supplies Batteries questions
What decision should the power supplies batteries guide support?
For Power Supplies Batteries, use it to record the relevant door, user, administration and failure requirements before equipment is selected. It is a planning aid, not a universal compliance certificate.
Does the power supplies batteries guidance apply to every opening?
For Power Supplies Batteries, no. Door construction, traffic, egress, fire significance, accessibility, environment and other building systems can change the appropriate design.
What site information is needed for power supplies batteries?
For Power Supplies Batteries, provide numbered doors, photographs or plans, user groups, operating hours, credential preferences, interfaces, known building constraints and expected changes.
Who should review a decision based on power supplies batteries?
For Power Supplies Batteries, the client and security designer should review it, with IT, building, fire, electrical, privacy or specialist contractors involved where their responsibilities are affected.
What should be tested after applying power supplies batteries?
For Power Supplies Batteries, test authorised and denied use, normal exit, physical closure, monitoring, relevant power or communications conditions and any integration from original event to operator outcome.
Discuss your access-control requirements
Share the door locations, approximate user numbers, site plans or photos, integrations and expected growth. Serious Security can prepare an itemised proposal after the requirements and site conditions are assessed.
