Intercom And Access Control Upgrades

Every building with an ageing intercom reaches the same point. Something fails, the part is obsolete, and the choice is between a workaround and replacing the system.

The decision is worth making deliberately rather than under pressure when the front door stops working.

The cabling decides the cost

This is the whole question, and it gets asked last.

Older systems used cabling that suits older systems. A modern replacement may need different cable, and running new cable through an occupied building means access to every apartment, chasing walls or finding routes through risers that may not have room.

That is why two buildings get very different quotes for what looks like the same job.

Where the existing cable can be reused, the upgrade is a head unit, handsets and configuration. Where it cannot, it is a cabling project with an intercom attached.

Systems that run over the building's existing data network, or wirelessly to handsets and phones, exist specifically to avoid the cabling problem, and they bring their own dependencies.

What a modern system adds

Video rather than audio only, which residents notice immediately and which reduces the number of people opening a door to someone they cannot see.

Calls to a phone, so deliveries and visitors can be answered when nobody is home. This is the feature that changes daily life in a building more than any other.

Access by fob, card or phone rather than by key, and the ability to cancel a lost credential rather than rekeying the building.

A log of who entered and when, which matters for buildings with recurring security issues.

Access control is the bigger win

The intercom is what residents notice. Access control is what solves problems.

A building on keys has no way to recover from a lost one except rekeying, and in practice nobody does it, so the number of uncontrolled keys grows every year.

Credentials can be cancelled individually. When someone moves out and does not return their fob, it is deactivated in a minute.

Zones matter too. Contractors, cleaners and building staff can be given access to what they need and nothing else, on the hours they need it.

What to settle before quoting

Where the cable can run. The single largest variable.

How many entry points. Front door, car park, side gate, bin store, each one is a reader and a lock.

Whether the locks are being replaced too. Electric strikes, mag locks and the door hardware itself all form part of the system, and old doors frequently need work before a new lock will hold alignment.

Emergency egress. Any electrically controlled door on an escape path has requirements about how it behaves in a power failure and in an alarm condition. That is not negotiable and it has to be designed in.

Who administers it. A system nobody knows how to add a resident to becomes a problem within a month. Whoever manages the building needs to be trained and needs the credentials.

Staging it

These do not have to happen at once. The front entry and the car park can be done first, with additional doors added later, provided the system chosen supports it.

That is worth confirming before committing, because some systems make expansion straightforward and others make it another project.

The work around the work

New readers mean penetrations, patching and painting. New handsets in apartments mean a plate that does not match the hole the old one left.

We take the electrical, the door hardware and the make-good as one job across electrical and building, so the building does not end up with a working system and a wall of patches. If yours is failing, let us look at the cabling first.
