Cable schedule
Use the diagram reference to follow the same connection from the main diagram into the detailed explanation below.
| Diagram ref | From | To | Cable type | Core count | Power or data | Maximum distance | Purpose / important notes |
|---|---|---|---|---|---|---|---|
| C1 | PIR Detectors | Alarm Control Panel | Security cable | 4-core minimum; 6-core recommended for a new run | Data/control | Not stated | PIR zone |
| C2 | Door / Window Contacts | Alarm Control Panel | Security cable | 2-core minimum; 4-core recommended | Data/control | Not stated | Perimeter zone |
| C3 | Alarm Control Panel | Compatible Keypad | Bus cable to manual | Normally 4-core; confirm exact bus | Data/control | Not stated | Keypad bus |
| C4 | Backup Battery | Alarm Control Panel | Manufacturer battery lead | Use supplied/manufacturer battery leads | Data/control | Not stated | Backup power |
| C5 | Alarm Control Panel | Siren / Strobe | Cable sized to load | 2-core minimum; 4/6-core if strobe, tamper or separate trigger | Data/control | Not stated | Siren output |
No maximum distance is invented. Where the exact figure depends on Ethernet design, voltage drop, current draw or the selected device, the schedule tells the installer to confirm it.
What the wiring actually is
Match each C reference to the same label on the main diagram and cable schedule. The line name alone is not a complete cable specification, so this table explains the physical cable, conductor or pair use, what it carries and how it normally terminates.
| Diagram ref | Cable shown | Physical path | Cable construction | Conductors or pairs | What it carries | Normal termination | Confirm before installation |
|---|---|---|---|---|---|---|---|
| C1 | Security cable | PIR Detectors to Alarm Control Panel | Stranded security/alarm cable. Four-core is common for a powered detector or many keypad buses; use six/eight core where extra circuits or spares are required. | Powered devices normally need positive and negative supply conductors plus a zone/relay pair or manufacturer bus conductors. | Low-voltage power and zone, tamper or proprietary bus data as defined by the panel/device. | Panel zone/bus and device terminals; end-of-line resistors belong at the supervised end only when the exact panel requires them. | Exact conductor functions, EOL value/configuration, cable gauge, bus topology, current draw, voltage drop and maximum bus length. |

| C4 | Manufacturer battery lead | Backup Battery to Alarm Control Panel | Dedicated stranded copper power cable sized for supply voltage, continuous/inrush current and voltage drop; commonly two-core for DC positive and negative. | Two conductors for DC power unless the manufacturer specifies a proprietary loom or additional monitoring cores. | ELV DC power or the named protected supply. Never infer voltage from cable colour. | Correctly fused PSU/device terminals with observed polarity; manufacturer battery leads remain unmodified. | Required voltage, polarity, load/inrush current, fuse, cable size, voltage drop, battery capacity and separation from 230-240 VAC. |

What "security cable" means
Security cable is a trade description, not a complete specification. On these pages it means multicore, stranded, full-copper extra-low-voltage alarm/access cable. A common Australian product is described as 14/0.20, approximately 0.44 mm2 per conductor, or nominal 0.5 mm2. The installer must still specify core count, conductor area, copper construction, twist/shield requirement, jacket/environment rating and permitted route. It is not Cat5e/Cat6, mains cable, fire-rated cable or automatically suitable for lock power.
| Cable description | Typical use | Important limitation |
|---|---|---|
| 2-core stranded copper | A simple unpowered contact, dry-contact trigger or separately designed DC power pair | Not enough for a powered PIR that also needs an alarm-contact pair. For lock power, calculate conductor size from voltage, current, inrush and distance. |
| 4-core stranded copper | Common for one powered PIR: positive and negative supply plus two alarm-loop conductors; also used for some proprietary four-wire keypad/module buses | Four cores do not define the function or resistor. Label both ends and follow the panel/device manual. |
| 6-core or 8-core stranded copper | Powered devices needing alarm, tamper, auxiliary functions or useful spare conductors | Do not join spare conductors to increase current capacity unless the equipment/cable design explicitly allows it. |
| Twisted or shielded security/bus cable | RS-485/OSDP and other buses only where the manufacturer specifies impedance, twist and shield treatment | Ordinary alarm cable is not automatically a compliant RS-485, OSDP or Ethernet cable. |
| Heavier two-core lock/power cable | Electric strikes, maglocks, sirens or other higher-current ELV loads | Common 0.5 mm2 alarm cable may be too small. Select 1.0 mm2, 1.5 mm2 or another size only after a voltage-drop and inrush calculation. |
Core colours are identification aids only; they do not create a universal positive, negative, zone, tamper or data standard.
Are any resistors required?
| Circuit | Resistor required? | Where it belongs | How to select it |
|---|---|---|---|
| Hardwired zone / PIR / reed | Depends on Location 266 | At the detector/contact end of the zone, not hidden at the panel | Solution 2000/3000 supports no EOL, 1 kohm, 1.5 kohm, 2.2 kohm, 3.3 kohm, 3.9 kohm, 4.7 kohm, 5.6 kohm, 6.8 kohm, 10 kohm, 12 kohm or 22 kohm globally. Split EOL uses 3.3 kohm/6.8 kohm, with a 1 kohm tamper arrangement where programmed. Read Location 266 and measure the fitted network; do not assume 2.2 kohm. |
| Codepad bus, battery, siren power or IP module | No zone EOL resistor in the normal supply/data conductors | Not applicable | Outputs and buses have their own wiring rules. Do not add a resistor simply because the cable is called security cable. |
Never choose a resistor by cable colour or by the phrase "security cable". First identify the exact input, panel model and programmed supervision mode. An EOL resistor belongs at the end of the supervised circuit; placing it across the panel terminals defeats cable supervision.
Power requirements
Confirm the selected equipment's supply method, PoE class or DC input, total load and backup requirements before ordering. Keep lock power separate from data-path assumptions, calculate voltage drop for low-voltage loads, observe battery polarity and isolate any 230-240 VAC work to an appropriately licensed electrician.
How the wiring path works
Read the physical cable path first, then power, relay or I/O paths, network addressing and finally app or cloud registration. A device that appears offline may have a physical link, power, addressing or configuration fault; Wi-Fi and cloud registration should not be used to hide an incorrect LAN design.
Practical installation sequence
- Confirm every exact device model and current manual.
- Confirm cable types, routes, separation and distances.
- Check PoE or DC power capacity and site voltage drop.
- Mount and cable devices with power isolated.
- Test continuity, polarity and earth/surge arrangements where applicable.
- Power one subsystem at a time.
- Activate and address network devices.
- Configure relay, call or recording behaviour only after the physical path works.
- Test local operation, remote operation and failure modes separately.
- Record final models, IP addresses, cable IDs, settings and diagram revision.
Common mistakes
- Assuming a port provides PoE without checking the port and total switch budget.
- Confusing a recorder's isolated camera ports with its main LAN uplink.
- Powering a lock from an unsuitable relay or supply.
- Guessing normally-open, normally-closed, polarity or resistor details.
- Ignoring voltage drop, surge exposure or power-failure behaviour.
- Treating app setup as proof that the physical cabling is correct.
Troubleshooting
| Symptom | Likely cause | Test | Corrective action |
|---|---|---|---|
| Device has no power | Incorrect supply method or exhausted PoE budget | Check port status and measure only with the correct procedure | Match the power source to the exact device manual |
| Device powers but is offline | Wrong LAN path, addressing or activation state | Confirm link lights, subnet, gateway and device state | Correct physical LAN and addressing before cloud setup |
| System works locally but not remotely | Internet, DNS, account or cloud registration issue | Prove local operation first, then test WAN services | Correct router or account configuration; do not recable a working local link |
| Relay or lock action fails | Wrong contact logic, power path or load assumption | Test relay and lock supply as separate subsystems | Use the exact manual and suitable lock PSU; confirm egress requirements |

Frequently asked questions
Can I buy cable using this guide?
Use the cable schedule and buying list to shortlist the cable, then confirm the exact equipment model, route, distance, environment and manufacturer requirements before ordering.
Can cable distance or power capacity be assumed from this drawing?
No. Confirm the selected devices, PoE budget, voltage drop, cable construction and current manufacturer instructions.
Where do terminal names and resistor values come from?
They must come from the exact current manual for the selected model. Do not transfer terminal names, polarity or resistor values from a similar product.
Can this replace the manufacturer manual?
No. It is a planning and support reference only and does not replace manufacturer instructions, licensed work, fire engineering, egress assessment or site commissioning.

Australian installation and safety notice
General guide only. Confirm current manufacturer instructions and site requirements. Work involving 230-240 VAC must be completed by an appropriately licensed electrician. Fire-release interfaces, emergency exits and door locking require project-specific compliance assessment. Keep mains and ELV cabling appropriately separated, isolate power before work, observe battery polarity and calculate voltage drop for the real load and cable run.
