Communications, Security & Specialist Systems

This element covers the low-voltage building systems that connect, secure and serve occupants: structured cabling and communications rooms; the incoming carrier and fibre connections; CCTV; access control and intercoms; master antenna and satellite television (MATV); audio-visual systems; public address; in-building mobile and emergency services radio coverage; and specialist systems such as nurse call in healthcare and aged care, and lift emergency telephones. Fire detection and warning systems have their own page.

These systems turn over faster than the building fabric: technology changes, vendors withdraw support, and the networks they rely on change. The biggest current change is the retirement of copper telephone networks, which affects every device that still dials out over a copper line.

What shortens life:

• Vendor end of support, especially for proprietary access control and nurse call.
• Network changes: copper switch-off, new broadcast standards.
• Cyber security requirements that retire insecure devices early.
• Hot, undocumented comms rooms.

Copper network retirement

Copper telephone networks are being retired: Britain's analogue network is retired on 31 January 2027, Australia has largely replaced copper with the NBN, and United States carriers are retiring copper lines. Lift emergency telephones, alarm and fire monitoring diallers, intercoms, door entry systems and some building management connections that depend on copper lines can go silent without warning. Lift emergency phones are the most serious: people trapped in a lift must be able to call for help.

Technology and vendor obsolescence

Analogue CCTV, proprietary access control and older nurse call systems lose spare parts and support; a single controller failure can disable a system. Proprietary access control ties the building to one integrator for cards, readers and changes.

Cyber exposure

IP cameras, access controllers and intercoms connected to the internet with default passwords and unpatched firmware are commonly compromised. Governments in all three countries have restricted certain camera and equipment manufacturers in government facilities, which affects buildings with government tenants.

Fire interface failures

Access-controlled doors on escape routes must release on fire alarm or power failure; interfaces broken by upgrades or rewiring can lock people in. Lifts with access control must still respond to fire service controls.

Coverage gaps

CCTV blind spots after fit-outs; access control bypassed by propped doors; weak mobile and emergency radio coverage in basements and large buildings; nurse call points missing in new rooms.

Cabling and comms room problems

Older cabling categories cannot carry modern bandwidth or power-over-Ethernet loads; risers fill with abandoned cable; comms rooms overheat; patching is undocumented, so faults take days to trace.

On site

• Analogue cameras (coaxial cable) and old recorders; cameras pointing at walls or obscured.
• Access control readers of an old proprietary type; doors propped open.
• Lift car emergency phones; label or test showing the line type.
• Comms rooms: temperature, cable congestion, labelling, equipment age.
• Intercom panels faded or failing.
• Weak mobile reception in basements and cores.

In the records

• Lift emergency phone and alarm monitoring line types and test records.
• Access control and CCTV vendor, version and support status.
• Fire interface test records for access-controlled doors.
• Cabling test results and documentation.
• Privacy policies and signage for CCTV.
• Nurse call test and maintenance records.

Findings are graded by what they demand: safety (can hurt someone now), failure (failed and damaging the building), condition (distress present and progressing), lifecycle (renewal due on age and exposure), deadline (a regulator or ordinance sets the date), check (investigate before sizing works) and nil (cosmetic or stable).

• Inventory of every system with vendor, model, version, age and support status.
• Line audit: every device that dials out (lift phones, alarm diallers, intercoms, BMS modems) and the line type it uses.
• Testing: lift phones, alarm monitoring, nurse call, intercoms.
• Fire interface testing of access-controlled doors and lifts.
• Coverage review: CCTV, access control, mobile and emergency radio.
• Cyber security assessment of IP devices and remote access.
• Cabling and comms room survey: categories, capacity, documentation, cooling.
• Compliance review: privacy for CCTV, emergency radio coverage where required, procurement restrictions for government tenants.

The report should give the inventory, the copper migration list, safety failures, support status, security risks and a replacement programme.

• Migrate devices off copper: lift phones and diallers to 4G/5G or IP with battery backup and monitoring.
• Fix fire interfaces and test them.
• Replace analogue CCTV with IP systems, designed for coverage and privacy.
• Replace proprietary access control with open-standard systems, with the owner holding licences and databases.
• Harden cyber security: segregated networks, changed credentials, firmware updates, removal of restricted equipment where required.
• Improve coverage: distributed antenna systems or emergency responder radio systems.
• Upgrade cabling and comms rooms; remove redundant cable; document patching.
• Replace nurse call systems with supported ones and full coverage.

• Battery backup for digital lift phones and diallers so they work during power failures.

Audits are lump sums. Copper migration is priced per device with monitoring contracts recurring. CCTV, access control and intercom replacement are priced per device plus head end. Cabling upgrades are per outlet or per floor. In-building coverage systems are lump sums. Nurse call is per bed or room.

Safety rectification and copper migration are code compliance or deadline-driven; replacement is lifecycle; maintenance contracts recur.

Digital line migration often needs new equipment in lift cars and panels as well as a new service.

• Australia. Cabling work requires registered cablers under the communications cabling rules; AS/NZS 3080 and related standards cover structured cabling; lift emergency communication requirements follow the lift standards; state privacy and surveillance laws govern CCTV; the copper network has largely been replaced by the NBN.
• United Kingdom. The analogue telephone network is retired on 31 January 2027, with all users to be migrated by then, affecting lift phones, alarm diallers and telecare; BS EN 81-28 covers remote alarms on lifts; UK GDPR and the Surveillance Camera Code govern CCTV.
• United States. Carriers are retiring copper lines under FCC rules; ASME A17.1 requires two-way communication in lifts; the International Fire Code and NFPA 1225 require emergency responder radio coverage in many buildings; federal procurement rules restrict certain telecommunications and video equipment.

• Inventory of systems with vendors, versions and support status.
• Line types for lift phones, alarm diallers and intercoms, and carrier notices.
• Fire interface test records.
• Cabling documentation and test results.
• CCTV privacy policy and signage.
• Nurse call test records.
• Any cyber security assessment.

• Lift emergency phone test records.
