Home/Nurse call/Construction sites
Wireless nurse call · evacuation alarm · construction sites · Melbourne & VictoriaWireless nurse call and evacuation alarm for construction sites, set up in a day and moved as the build moves.
Battery call points at the crane base, the hoist, the excavation, the first-aid room and every level, with no cabling. One press raises a first-aid call: the first-aid room display, the site phones, the first aider's pager and a logged record for the safety file. A second set of points raises the evacuation siren across the whole site, with a distinct tone and an all-clear. Two systems on one set of radios. Hire it for the life of the build or buy it and take it to the next job.
- No cabling. Call points run on batteries and long-range radio, so they go where the risk is
- Works before the site has power or internet. The 4G kit brings its own connection
- First-aid call and evacuation alarm with different tones, so nobody has to guess which it is
- Every call, alarm and drill logged with the time and the point, ready for the site diary

Level 6, 10:40 am. Someone goes down. The first aider knows in seconds.
A worker hits the call point by the hoist. The site siren sounds, the first-aid room display shows "Level 6, hoist", and the first aider's phone rings with the same message. The clock starts, and the call stays up until someone on the spot clears it.
- 1Press the call point. Every point is labelled with its location.
- 2Siren, first-aid room display, site phones and pagers all say where.
- 3The first aider clears the call at the point. Time to respond is in the log.
The phone alert is a real call, not an app notification, so it gets through with the phone in a pocket on a noisy site. An evacuation alarm sounds a different tone on every siren at once and rings the same phones with "Evacuate".
A first-aid room needs an emergency call system. Every site needs a way to raise the alarm.
Safe Work Australia's model Code of Practice for first aid says access to a telephone or an emergency call system should be part of every first-aid facility, and that high-risk workplaces such as construction with 100 or more workers should have a first-aid room. WorkSafe Victoria's compliance codes follow the same line, and your site's emergency plan has to show how a worker on level 9 gets help to them.
The same plan has to say how the whole site is told to evacuate. An air horn on the ground floor doesn't reach level 9 or the basement, a mobile phone group doesn't reach the person without theirs, and nobody writes down when the alarm was raised or how long the site took to clear.
A site nurse call and evacuation system does both. One press gets the first aider to the right level; a second kind of press sounds every siren on the site. Both are on record.
Call points where the risk is, sirens where the people are.
Each site gets a layout drawn from its own risks and its own emergency plan. These are the parts we build it from.
Weatherproof call points
Big, labelled, battery-powered buttons at the crane base, hoist landings, excavations, plant zones, amenities and the first-aid room. Screw or strap them to a post, a fence panel or a hoist frame, and move them as the build moves.
Every level · plant · amenitiesFirst-aid room display and siren
A display in the first-aid room or site office shows which point is calling and how long it has been waiting. A siren and strobe let the whole site know a call is up.
First-aid room · site officeSite phones ring
The first aiders, the site manager and the HSE lead get a real phone call that says the location. Add or remove people in a minute when the crew changes.
First aiders · supervisorsPagers and text alerts
For sites that run pagers, or a first aider who needs a message rather than a call, the same event goes out as a page or a text with the location.
OptionalEvacuation siren and warning
Klaxon Super M motorised sirens, 127 dB at one metre, the same siren used for site evacuation across the industry. One or two cover a whole site; strobes and sounders go inside plant rooms and other loud areas. Triggered from red evacuation points or the site office, ended with an all-clear, and a drill mode logs the practice without alerting the phones.
Every level · evacuation points · site officeEvery call, on record
Time raised, point, who was alerted, time cleared, and how long an evacuation took from the first siren to the all-clear. Exported for the site diary, the incident report and the WHS audit. Weekly tests and drills are logged too, so the test register writes itself.
Site diary · incident reports · auditsFirst-aid call and evacuation alarm, kept apart where it matters.
Same hub, same battery radio, same log. Different buttons, different tones, different people told, so a first-aid call never empties the site and an evacuation never gets mistaken for one.
| First-aid callGreen call points | Evacuation alarmRed evacuation points | |
|---|---|---|
| Who presses it | Anyone near an injured or unwell worker | Wardens, supervisors, or anyone who sees a fire, collapse or gas risk |
| What sounds | A short alert tone and a strobe, so the site knows a call is up without stopping work | The rising and falling evacuation wail from the motorised sirens, heard across the whole site, until the all-clear |
| Who is told | First aiders, site manager and HSE lead by phone or pager, with the location | Everyone on site by siren; wardens and management by phone with "Evacuate" |
| How it ends | Cleared at the call point by the first aider | All-clear tone from the site office or the chief warden's point after the roll call |
| What is logged | Time raised, point, time cleared, response time | Time raised, point, time of all-clear, time to clear the site; drills marked as drills |
| Testing | Weekly test press per point, logged | Siren controller checked in by the hub daily; a short weekly sound test and drill mode for practice evacuations, both logged |
The evacuation alarm is a temporary site system for the construction phase. When the building's own emergency warning system is commissioned, ours comes down.
Three steps, and the last one repeats for the life of the build.
Walk the site with us
We go through your emergency plan and the site layout with the HSE lead: where the first-aid room is, where the crane and hoist are, which levels are live, and how the crew will grow.
About an hour · freeInstall in a day
The hub goes in the site office, call points and evacuation points go where the plan says, the sirens go up where the site can hear them, and the phones and pagers are set up and tested with your first aiders and wardens before we leave.
Usually one dayMove it as the build moves
New levels, a second crane, the hoist coming down: call points move or get added in minutes. We service it for the life of the job, then take it away or hand it over for the next one.
Moves and adds included on hireBuilt to keep working on a building site.
Long-range radio, battery call points, and a hub that checks on all of them.
The call points use the same long-range, low-power radio our sensors use in aged care. It reaches across a site and through concrete far better than WiFi, and a call point runs for years on its battery, not weeks.
- Works without site internet. The siren, display and phones on site are driven locally. The 4G kit adds off-site calls and remote support.
- Checks itself. If a call point stops reporting or its battery runs low, the hub tells us before it matters.
- Sirens on the same radio. Each Klaxon Super M has its own radio controller, so the hub fires every siren on the site together within seconds, with no cable back to the office.
- Nothing to charge or dock. Points stay where they are bolted. No pendants left in a ute.
- The same hub we use for hospital nurse call. It also runs our aged-care and healthcare integrations, so it is not a construction-only gadget.
Weatherproof, dust-proof call points
Rated for outdoor use, with a guarded button so a knock from a wheelbarrow doesn't raise a call.
Covers the whole site
A single hub covers most sites; a repeater covers deep basements and long linear jobs.
Runs off site power or a battery
The hub and the first-aid alerts run from the site office supply or the battery on our solar camera trailer. The motorised sirens take mains power, so they go where the site has it: the office, the hoist, the crane base.
Shares a rig with site cameras
If we're already putting solar and 4G cameras on the site, the nurse call rides on the same trailer and the same connection.
Hire it for the build, buy it for the business, or bundle it with the cameras.
Quoted per site after the free walk-through, based on how many call points the plan needs.
Hire for the life of the build
A weekly rate that covers the hub, the call points, the evacuation points, the sirens and display, moves and additions as the site changes, and support until handover.
- We install, move and remove it
- Faulty or damaged points swapped, not argued about
Buy it and take it to the next job
Own the hub and a set of call points, add points per project, and we reconfigure it for each new site. Cheapest over three or more builds.
- Configured for each site by us
- Optional annual service and battery check
Bundle with the camera trailer
Nurse call and site security on one solar and 4G rig. One connection, one supplier, one number to call when something on site changes.
- See construction site cameras
- Both move to the next site together
Any site where help is more than a shout away.
Multi-storey builds
Call points at every hoist landing and crane base, a motorised siren high on the structure, a display in the first-aid room, and the layout grows a level at a time.
Civil and infrastructure
Long, linear sites where the first aider is a drive away. Points at the work fronts, repeaters along the alignment.
Shutdowns and refurbishments
A short job inside a live plant or hospital, with no permission to run cable. Up in a day, gone when the job is.
Regional and remote sites
No mains, no fixed internet. The 4G kit and a battery rig cover it, and we support it remotely.

Which areas do you cover?
Send us the site plan. We'll send back a layout and a price.
A free walk-through, a call-point layout drawn against your emergency plan, and a quote for hire or purchase. Or call and talk it through first.
A site nurse call and evacuation alarm system supports your first-aid arrangements and emergency plan during construction; it does not replace first aiders, calling 000, fire wardens, or the certified fire detection and emergency warning system installed for the finished building.

What a site requires is set by the regulator and the site's own risk assessment, not by us. Klaxon is a trademark of Klaxon Signals Ltd. Hire and purchase pricing is quoted per site.
