Security / Access Control Cable
Security Cable is not a single roll 22/4, but a system cabling ecosystem for residential alarms, commercial access control, OSDP upgrades, outdoor gates and noisy environments. The complete solution must cover the controller, card reader, electric lock, door sensor, REX, alarm panel, sensor, power box and fire alarm release interface.

VOLTIC STONE Security lines should be layered by Alarm Wire, Access Control Composite, OSDP/RS-485 Professional, Wet/Outdoor Pack. Ordinary security cable cannot be mixed with fire alarm cable, unless the cable jacket and certificate are clearly FPL/FPLR/FPLP and the project allows it.
The goal of pre-embedding alarm lines in new homes or major renovations is to make each zone clear, easy to maintain, and accessible to traditional Honeywell/DSC or modern conversion modules.
Alarm control panel, keypad, door/window contact, PIR motion, glass break, siren/bell, communicator, backup battery.
Door and window magnets usually return to the host or partition summary from various points; PIR/glass break/keypad use 4 conductors; siren/aux power uses larger wire gauges to return to the host or power supply end.
22/2 for door and window magnetic economy points; 22/4 for PIR, glass break, keypad and reserve; 18/2 or 18/4 for siren/aux power.
Home-run is more conducive to troubleshooting, while daisy-chain saves more wires but is difficult to maintain; EOL/SEOL/DEOL connection methods are based on host and project requirements; smoke detectors and life safety circuits should not be mixed with standard security cable logic.

Jacket marking, listing documents, equipment terminals and local regulations must be checked before installation.
A door is usually not a wire, but a multi-functional combination of card reader, electric lock, door sensor, REX, fire alarm release, doorbell/intercom, etc. The comprehensive line value is to reduce the number of lines pulled on the jobsite and reduce identification errors.
Access controller, reader/keypad, electric strike or maglock, door contact, REX button/sensor, power supply, FACP release relay.
From the controller/power box to the door, the reader, lock power, door contact, and REX are connected in groups; the fire alarm release interface is connected according to the requirements of the access control power supply and fire alarm system.
Access Control Composite: 18/4 lock power + 22/6 or 22/3PR reader + 22/2 door contact + 22/4 REX; CMR/CL3R or CMP/CL3P as per installation space.
Lock power must check the current and voltage drop; fail-safe/fail-secure and fire alarm release logic must be in accordance with local requirements; reader data line shielding should be handled according to the manufacturer manual.

New projects and high-security projects are increasingly leaning toward OSDP. The system goal is to use shielded twisted pair communication pairs that are truly suitable for RS-485, rather than just retitle ordinary multi-conductor wires.
OSDP reader, access controller, 12/24VDC power supply, RS-485 bus, termination resistor, shield/drain handling.
The controller to the card reader uses a power line pair + a shielded twisted pair communication line pair; long distance, multiple card readers or high-interference environments are handled according to the RS-485 topology to avoid arbitrary star formation.
18/2 power + 22/1PR or 24/1PR shielded twisted pair; OSDP composite can be added to door contact, REX, and lock power line groups.
Termination resistors, baud rates, shield grounds, and old Wiegand line reuse boundaries are all accounted for. Don't promise that all old lines can run OSDP stably.

Outdoor gates, warehouses, industrial areas and long-distance access control are more likely to encounter problems with wet areas, UV, strong motor interference and lock power supply voltage drop. The system goal is that both the wire structure and the environmental rating are clear.
Gate operator, long-run reader, maglock/electric strike, power supply, intercom, door/gate contact, surge protection, weatherproof enclosure.
From the in-building controller or power box to the outdoor door point, which may pass through conduit, underground pipes or wet areas; reader communication and lock power group management.
Wet location / sunlight resistant / OSP composite; use 18/2, 16/2 or larger wire gauge for longer lock power loops; use all-shielded or reader pair shielded construction for noisy environments.
Indoor CMP does not equal direct burial; outdoor projects need to confirm UV, wet, conduit, grounding and surge protection.

Only if the conductor, listing, and guide requirements specifically permit FPL/FPLR/FPLP or a compliant alternative. The general security line page cannot by default advertise that it can be used for fire alarm life safety systems.
A door usually has multiple sets of lines such as reader, lock, door contact, REX, etc. Composite cable can reduce labor, reduce the probability of connection errors, and is more like the Product Line of a professional supplier.
Next Step
If the equipment, distance, installation space and usage have been confirmed, you can enter the corresponding Product Line to select specifications; if the project involves commercial space, underground, fire alarm or special listing requirements, it is recommended to submit the information for confirmation first.
Next Step
Tell us the usage scenario, cable specifications, length, color and quantity, and we will help confirm the next step according to the device, distance, environment and applicable boundaries.
When you don't know what kind of wire to buy, how many conductors, and what length, start here.
