Intercom Call Station Installation in Katy, TX 77492
A front door four businesses share. A school wing that has to lock at eight in the morning. A warehouse man-door taking freight before sunrise. Each one is a call station problem, each one answers to a different set of rules, and EVOTECH builds them so the door stays secure, legal to exit and simple for staff to run.
Call stations for Katy businesses, schools and multi-tenant buildings
The commercial side of Katy is nothing like the residential side. Along the I-10 frontage, Park Row and out toward Clay Road you find flex bays, suites carved out of a single shell, medical and dental offices, contractor yards, storage, churches with school wings, and a lot of buildings where the landlord owns the front door and the tenant owns the problem.
| Property | What the station has to solve |
|---|---|
| Multi-tenant office suite entrance | One shared door, several businesses, each needing its own call route and its own after-hours behaviour. |
| Medical or dental suite | A locked door with a waiting room behind it, staff who cannot leave a patient, and privacy at the plate. |
| Church or school entry vestibule | Open on Sunday, locked during class hours, with somebody looking at a face before the second door releases. |
| Warehouse man-door and dock | Early freight, loud environment, plate mounted clear of forklift travel and pallet corners. |
| Contractor yard or storage gate | Vehicle-height station, weather exposure, credentials for crews that change job to job. |
| Restaurant back-of-house delivery door | Deliveries before opening, greasy hands, a plate that survives being hit with a hand cart. |
The common thread is that a business door has to keep working when the person who usually answers it is busy, out, or no longer employed there. That is a design requirement, and it is the one most often skipped.
Mounting height, reach range and the rule nobody gets to negotiate
Two constraints shape every commercial station we install, and neither is a matter of taste.
The first is reach. A call button on a public-facing door needs to be usable by somebody in a wheelchair, which means it goes at an accessible height with a clear approach in front of it, not at whatever height happens to be convenient for the installer’s drill. A plate mounted behind a planter is not reachable even if the number on the tape measure is right.
The second is egress, and it is absolute: a door that locks people out must never lock people in. Where a magnetic lock is involved, it has to release on the fire alarm and it has to release on the building’s request-to-exit path, and that interconnection is inspected. We coordinate with your alarm contractor so the two systems agree with each other, and we build to what your authority having jurisdiction and fire marshal require.
To be clear about our role: we are a licensed, insured low-voltage contractor, not your code official. On anything involving locking hardware and life safety, the fire marshal and the AHJ have the final word, and we would rather redo a detail than argue with an inspector on your behalf.
SIP, analog, and the day your phone system changes
A commercial station can answer in two broad ways, and picking wrong is the most expensive mistake in this category.
A SIP station registers on your phone system as an extension. Press the button and a desk phone rings, or a ring group rings, or a softphone on somebody’s mobile rings. It is enormously flexible, it follows your existing call routing, and it inherits every feature your phone platform has. It also inherits every dependency, which means a carrier migration, a PBX replacement or a cloud provider changing its plans can silently take your front door with it.
An analog or proprietary station rings a dedicated wall unit and knows nothing about your phone system. Far less clever, and far less likely to be affected by a decision made in somebody else’s boardroom.
What we actually recommend for most Katy businesses is one of each function: a hardwired path that answers the door regardless of what your telecom vendor is doing this quarter, plus a SIP or app layer on top for convenience and remote answering. If your building has a single door and no IT staff, the simpler system is usually the right one, and we will say so even though it is the smaller sale.
Doing the work without closing your front door
A business door is revenue. The install plan matters as much as the hardware.
- Keep the old one live. Wherever the opening allows, the existing station keeps answering until the replacement has taken a real call. Cutover is minutes, not a day.
- Work the quiet window. Evenings, early mornings and weekends are normal for us, and a medical suite is generally happier with a Saturday than with a Tuesday afternoon full of patients.
- Landlord first. In a multi-tenant building the front door is almost always a common element, so the property owner or manager signs off before a tenant’s project touches it.
- Badging and escort. Managed business parks around Park Row and the 99 corridor often require check-in and a certificate of insurance on file. Ours is current and we send it ahead.
- Dust control. Coring a wall in a clinical or food environment is a containment job. We mask, we vacuum at the bit, and we clean the space before we leave it.
Documentation, admin accounts and the day your office manager leaves
The most common commercial entry failure we get called to fix is not a broken station. It is a working station that nobody can administer, because the one employee who set it up has moved on and took the login with them.
So the system gets registered to the business, not to a person. The administrator account uses a company address that survives turnover, a second named manager is added from day one, and we walk at least two people through adding a user, removing a user, and changing who the door rings.
The paperwork you keep is short but it is the difference between a five-minute change and a service call: a device list with models and locations, a cable map with both ends labelled to match what is actually printed on the jacket, the door release wiring noted where it ties into the lock hardware, and the administrator details in writing.
Low-voltage has been the whole trade at EVOTECH IT LLC since around 2004, and the map we cover stretches from Katy and Cypress across Houston and south to Sugar Land, Richmond and Fulshear. We are licensed, insured and carry a 5.0-star rating. The reason we hand over this much paperwork is simple enough: we would rather your next call be about the next building than about a password.

Frequently asked questions
Can the station ring our phone system instead of a box on the wall?
Yes. A SIP station registers as an extension and rings whatever your phone platform tells it to, including a desk phone, a ring group, or a mobile app for a manager who is off site. The trade-off is that your door now depends on your phone system, so for most businesses we pair it with one hardwired answering point that works regardless.
Four suites share one front door. How does that get wired?
One station with four call routes, on one cable, tied to one door release. Each tenant answers only their own calls and sees only their own visitors, and each can have its own hours. The alternative, four separate systems stacked beside one door, looks exactly as bad as it sounds and costs more to maintain.
Will the door unlock automatically if the fire alarm goes off?
Where a magnetic lock is used, it must, and that release is wired and inspected as part of the life-safety system. We coordinate that interconnection with your alarm contractor rather than improvising it, and the fire marshal and your authority having jurisdiction set the requirements we build to.
We are a church with a school wing. Can the doors behave differently on Sunday than on a Wednesday?
That is exactly what a schedule is for. Class hours can run locked with every visitor screened at the vestibule before a second door releases, services can run unlocked, and a special event can be switched by hand from a phone. The important part is deciding who holds the authority to change it, and we set the permissions to match.
Can you do the work after hours so we are not propping the front door open all day?
Yes, evenings and weekends are routine for commercial work and we would usually suggest it. Where a building allows it we also leave the existing station answering until the new one is proven, so there is no window at all where a visitor cannot reach somebody inside.
What happens when the person who set it up leaves the company?
Nothing, if it was set up correctly. The administrator account belongs to the business at an address that outlives any one employee, a second manager has access from the start, and the written handover tells the next person what to do. If you have already inherited a system nobody can log into, that is a common call and often recoverable.
