Building & Infrastructure

Configurable 12/24 V DC power control for building systems, from smoke vents to access control.

The challenge

When the alarm goes off, the vents and doors have to work.

Many of the systems that help people get out of a building safely run on 12 or 24 V DC.

Hard-to-reach equipment

Actuators on high windows, louvres and smoke vents are hard to get to for inspection and repair.

Fuses, relays and terminals

Smoke control inspections check fuses, isolators, relays, contactors, cables and terminals. Each one is a point that can fail.

Faults found late

A failed circuit may not show until the next scheduled test, or until it’s needed.

How Hardwire helps

Configurable DC power control for buildings.

Configurable protection

Per-circuit electronic protection, set to suit each actuator, cable and load.

Programmable logic

Outputs respond to fire alarm signals, wind and rain sensors, timers or a manual override.

Current and fault logging

Output current and trip history can be logged on board, set up to suit, and read on site with a laptop.

Fewer relays and fuses

Solid-state outputs replace banks of relays and fuses in the control cabinet.

Typical applications

Where it’s used in buildings.

Selected 12/24 V DC circuits in commercial and public buildings. Life-safety circuits are designed with the project’s fire engineer, and each circuit is checked for current, inrush and cable rating at installation.

At Ākau Tangi Sports Centre in Wellington (formerly the ASB Sports Centre), a Hardwire PDM controls the actuators on the high-level windows, so they open and stay open if the fire alarm goes off.
