Smart Home Installation Standard
Smart Citizens' engineering standard for planning, cabling, mounting and powering smart-home devices in UAE villas and apartments.
The essentials
- Applies to every Smart Citizens residential installation
- Enforces structured cabling, labeled runs and documented terminations
- Requires isolated low-voltage circuits and surge protection
- Defines mounting heights and back-box standards per room type
- Mandates as-built documentation before commissioning
Purpose
This standard exists to ensure Smart Citizens installations are safe, reliable, and maintainable for at least ten years. It removes ambiguity from field decisions and sets a consistent quality bar across every site.
Scope
Applies to all residential and light-commercial installations delivered by Smart Citizens engineers, including new build, retrofit, and developer handover projects across the UAE.
Design principles
Principle 1
Serviceability over shortcuts — every device must be replaceable without opening a wall
Principle 2
Redundancy for critical paths — gateways, network cores and power feeds
Principle 3
Documented before energised — no undocumented cables leave a site
Principle 4
Low-voltage isolated from mains at all times
Principle 5
Every install must survive a power event without data loss
Engineering requirements
Engineering requirements
- Structured Cat6A cabling for every wired IP device
- Certified terminations at both ends of every run
- Isolated 24V and 12V DC rails with individual breakers
- Surge protection on incoming mains and on the network core
- Ferrules on every stranded conductor entering a terminal block
- Metal back-boxes for keypads, touch panels and mains switching
- IP44 minimum for outdoor and wet-area devices
Best practices
Pathways
Pathways: Pre-plan all conduit routes with the MEP contractor before civil works
Loop lengths
Loop lengths: Keep Cat6A runs under 90 m end-to-end
Slack
Slack: Leave 2 m service loops at every gateway location
Colour
Colour: Use consistent cable colours per subsystem (blue = data, red = 24V, black = mains)
Photos
Photos: Photograph every open wall before closing
Installation workflow
Installation workflow
How it works
1. Site survey
Walk every room with the design; mark device positions, cable pathways and gateway locations on the floor plan.
2. Design freeze
Issue a signed installation drawing set — no field changes without a change note.
3. First-fix cabling
Pull all Cat6A, control and power cables before wall closure; label every end.
4. Back-box installation
Install metal back-boxes at standardised heights per room-type schedule.
5. Second-fix devices
Terminate, mount and power every device after finishes are complete.
6. Continuity test
Test every cable for continuity and Cat6A performance to TIA-568 Category 6A.
7. Power-on and label
Energise circuits, verify voltages, apply final labels at both ends of every run.
8. Handover to commissioning
Deliver signed installation dossier to the commissioning engineer.
Configuration & programming workflow
Configuration & programming workflow
How it works
1. Boot images
Flash each gateway with the current Smart Citizens factory image before dispatch.
2. IP plan
Apply the site IP plan; reserve static leases for gateways, hubs and keypads.
3. Device provisioning
Join devices to their designated network segment (IoT VLAN by default).
4. Naming
Apply the Smart Citizens naming convention to every device before pairing.
5. Firmware baseline
Update every device to the approved firmware baseline for this site.
Commissioning steps
Commissioning steps
How it works
1. Circuit verification
Verify every circuit responds to its assigned control and reports state correctly.
2. Scene test
Execute every published scene and confirm end-to-end behaviour.
3. Sensor calibration
Calibrate presence, lux and temperature sensors under real occupancy.
4. Automation dry-run
Run each automation on manual trigger; confirm no unintended side effects.
5. Failover drill
Simulate loss of internet and of the primary gateway; confirm local scenes still operate.
Validation checklist
Validation checklist
- All wired devices reachable from the local network
- All battery devices reporting healthy signal and battery
- Every keypad button executes its documented action
- Every scene is reproducible three times in a row without error
- Local-only operation works with WAN disconnected
- All firmware at approved baseline
- As-built drawings match physical install
- Closing walls before continuity testing
- Mixing low-voltage and mains inside the same back-box
- Skipping torque marking on terminal blocks
- Labels handwritten with marker pens
- Firmware updated ad-hoc during commissioning
Quality assurance checklist
Cable dressing
Cables in each panel are dressed, tied and free from strain.
Label integrity
Every label is legible, machine-printed and matches the drawing.
Torque check
Every terminal has been torqued to manufacturer spec and marked.
Grounding
Ground continuity verified on every metal enclosure.
Cleanup
Site is left cleaner than found; all cable offcuts removed.
Acceptance criteria
| Feature | Target | Verification method | Priority |
|---|---|---|---|
Cat6A permanent link | Pass TIA-568 Category 6A | Certified Fluke tester report per run | High |
Device response time | < 400 ms local | Automated ping + control loop test | Medium |
Local operation without WAN | 100% of scenes | Manual disconnect drill | High |
Label match | 100% | Random 20% audit against drawings | Medium |
IP44 in wet areas | 100% of outdoor / wet devices | Physical inspection | High |
Risk matrix
| Feature | Likelihood | Impact | Mitigation |
|---|---|---|---|
Undocumented cable run | Medium | High | Photograph every wall pre-closure; drawings updated within 24 h |
Shared low-voltage / mains conduit | Low | High | Separate conduits enforced; QA sign-off required |
Firmware drift between sister sites | Medium | Medium | Baseline firmware pinned per project |
Power event data loss | Medium | Medium | UPS on network core and primary gateway |
Common mistakes & troubleshooting
Troubleshooting tips
How it works
No link on a wired device
Test the permanent link with a certified tester; re-terminate if margin is below spec.
Intermittent keypad
Check torque on the terminal block; keypads often fail from loose neutrals.
Sensor false-triggers
Verify mounting height and check for reflective surfaces within the sensor field of view.
High local latency
Move the device to the IoT VLAN and confirm gateway is on the same broadcast domain.
Documentation requirements
Documentation requirements
- Installation drawing set (as-built)
- Cable schedule with tested lengths and pass/fail
- Device inventory with MAC, serial, firmware and location
- IP addressing plan
- Site photographs (pre- and post-closure)
Maintenance timeline
Maintenance timeline
How it works
Monthly
Review health dashboard; investigate any offline devices.
Quarterly
Torque re-check on high-current terminals; label audit.
Annually
Full firmware roll-forward; UPS battery test; cable margin re-test on 10% random sample.
UAE / GCC considerations
UAE builds combine high ambient temperatures, high humidity in coastal areas, and MEP practices that vary between developers. This standard mandates additional derating for enclosures exposed to non-conditioned spaces (garages, plant rooms) and requires vapour-tight seals for any conduit passing between conditioned and non-conditioned zones.

Frequently asked questions
Frequently asked questions
Does this standard apply to retrofits?
Yes — with documented exceptions where physical constraints prevent full compliance. Every exception must be approved and recorded on the installation dossier.
Can we use existing developer cabling?
Only after a certified Cat6A permanent-link test. Un-tested legacy cabling is not accepted for control-critical circuits.
What torque tools are approved?
Any calibrated torque screwdriver with a valid calibration certificate less than 12 months old.
