What installation includes, by system
| System | Work |
|---|---|
| Fire alarm | installation of control and indicating equipment, smoke, heat, manual call point and linear detectors, addressable modules; loop wiring with fire-resistant cables |
| Fire warning and evacuation | voice and audible alarms, illuminated “Exit” signs, amplifiers, warning lines with sound pressure calculation |
| Intruder alarm | intrusion detectors, panic buttons, control panels, connection to the central monitoring station |
| CCTV | IP and analog cameras, video recorders and servers, PoE switches, monitors at security posts |
| Access control | controllers, readers, electromagnetic and electromechanical locks, turnstiles, barriers, integration with the fire alarm to unlock doors in case of fire |
| Structured cabling | cable routes, outlets, network cabinets and patch panels, line testing |
| Energy metering | meters with communication interfaces, data collection devices, communication channels, data collection setup |
| Cable TV | distribution network, amplifiers, splitters, subscriber outlets |
| Intercom and telephony | door entry panels, subscriber units, IP PBX and telephone lines |
| Environmental monitoring | sensors, RS-485 lines, radio gateways, control cabinet |
Work sequence
- Preparation
Review of the detailed documentation, incoming inspection of equipment and materials, coordination of the schedule with other contractors.
- Cable routes
Cable trays, trunking, flexible conduit, embedded elements; fire protection system lines are routed separately from other low-voltage lines as required by the standards.
- Cable pulling
Cables with fire performance ratings per GOST 31565-2012, slack at connection points, labeling at both ends.
- Equipment installation
Detectors, cameras, readers, cabinets; distances and mounting heights as per the design and data sheets.
- Terminations and line testing
Measurement of insulation and loop resistance, testing of structured cabling links.
- As-built documentation
As-built drawings, certificates of concealed works, logs, in accordance with the procedure for keeping as-built documentation approved by Order No. 344/pr of the Russian Ministry of Construction.
Common problems we avoid
- ordinary cable instead of fire-resistant cable in voice evacuation and fire alarm lines;
- detectors next to supply air grilles and under beams, where smoke does not reach the sensor;
- no labeling, so a year later the system cannot be maintained;
- access control that does not unlock doors on a fire alarm signal;
- insufficient CCTV archive capacity due to an incorrect bitrate calculation.
Frequently asked questions
Can systems be installed at an operating facility?
Yes, the work is scheduled by zone and time so as not to interrupt the customer's operations.
What does the customer receive after installation?
The installed system, as-built documentation, certificates of concealed works, equipment data sheets and certificates and, after commissioning, test reports.
