BMS & Controls

Building Management Systems & Controls

Electrical and controls support for commercial building systems, integrating plant, field devices, control panels and building-management infrastructure.

From power and control wiring to sensors, actuators, interfaces and fault diagnosis, ElectroLogic supports the electrical layer that allows building systems to operate together.

Connected building systems

Understanding the system, not just the circuit.

Modern commercial buildings rely on multiple systems operating together. BMS panels, sensors, actuators, relays, contactors, inverters, meters, ventilation plant, fire interfaces and lighting controls can all affect how a building behaves.

ElectroLogic provides electrical and controls support across these interconnected systems, helping identify faults, complete alterations, install field devices and support integration works in live commercial environments.

Electrical faults are not always electrical-component faults. Understanding the control sequence is often what finds the real problem.

Technical capabilities

Support across the electrical control path.

BMS control panels

Power supplies, protective devices, relays, contactors, terminals, control wiring and field connections.

Sensors & field devices

Temperature, pressure, airflow, CO₂, occupancy and other building-services sensors where electrically applicable.

Actuators & control devices

Valve actuators, damper actuators, relays, contactors and electrically controlled field equipment.

Plant control interfaces

Electrical interfaces for AHUs, FCUs, pumps, fans, ventilation systems and other mechanical plant.

Variable speed drives

Electrical support, control wiring, enable signals, fault investigation and interface checks for VSDs and inverters.

Fire alarm interfaces

Plant shutdowns, dampers, ventilation interlocks and other control interactions where applicable.

Meters & monitoring

Electrical metering, current transformers, sub-metering and data points used within building-management systems.

Control wiring

ELV and control cabling, panel wiring, field connections, termination, identification and alterations.

BMS communications support

Electrical and physical-layer support for connected devices, communications wiring and interfaces such as Modbus where appropriate.

Fault diagnosis

Tracing control signals and checking supplies, relays, sensors, actuators, interlocks and plant-response sequences.

Controls alterations

Adding or modifying field devices, relays, interfaces and wiring to support building changes or plant replacements.

Testing & commissioning support

Electrical verification, point-to-point and device-operation checks alongside specialist BMS engineers where required.

Fault diagnosis

Finding where the control sequence breaks down.

A reported plant fault can begin at any point between the incoming supply, control command, field device and mechanical response.

Find the point where the sequence stops.

FM & controls coordination

Working alongside FM teams, BMS engineers, mechanical contractors and specialist controls providers.

Controlled intervention

Safe isolation, point identification and methodical testing to avoid unnecessary disruption.

Clear technical reporting

System integration

The interfaces between systems matter.

ElectroLogic supports the electrical, field-device, wiring, relay, interface and diagnostic side of integrations, working alongside the relevant specialist engineers where software configuration is required.

Successful integration depends on both the software command and the physical device responding correctly.
BMS ↔ ventilation
BMS ↔ electrical metering
BMS ↔ fire alarm
BMS ↔ access control
BMS ↔ lighting controls
BMS ↔ plant control panels
BMS ↔ sensors / field devices
BMS ↔ energy monitoring
