How many horn loudspeakers were included?

The project scope included eight outdoor horn loudspeakers positioned to project alert tones and recorded instructions across nominated outdoor and circulation areas.

Why were visual warning beacons included?

Visual warning beacons reinforce an active audible alert and can improve awareness where distance, activity or background noise may affect audibility.

Can authorised staff use portable and fixed controls?

Yes. The system included a portable handheld transmitter and a fixed wall-mounted activation point so the school could align activation with nominated staff and approved procedures.

Does this system replace a certified fire alarm or EWIS?

Not automatically. Any fire alarm, occupant warning, EWIS or statutory certification requirement must be confirmed separately with the relevant consultant, fire engineer, certifier and school representative.

Project summary

Clear instructions for different emergency situations

The school required more than a single warning siren. It needed recognisable alert functions, consistent recorded instructions, strong outdoor projection and practical activation controls for authorised personnel.

The completed system combines wireless activation, message playback, directional horn loudspeakers and visual warning equipment in one coordinated emergency communication workflow. The user-facing controls follow familiar school terminology rather than technical equipment labels.

Emergency alert functions

Different messages for different school procedures

Distinct alerts help staff, students and visitors understand what is happening and what action is required without relying on an improvised live announcement during a stressful event.

Red alert

Evacuation

A recognisable alert tone and recorded voice instruction support the school’s nominated process for moving occupants toward the approved assembly procedure.

Blue alert

Lockdown

A separate lockdown message distinguishes shelter-in-place action from evacuation and provides consistent instructions across the selected school areas.

Return to normal

All-clear

An all-clear message communicates that the active event has ended and supports an orderly return to the school’s normal operating procedure.

Planned verification

System testing

A dedicated test function allows authorised personnel to verify system operation and staff familiarity without presenting a test as an active emergency.

The project requirement

Extending emergency communication where outdoor coverage matters

Classrooms are only one part of a school environment. Playgrounds, walkways, covered outdoor areas and circulation spaces also require appropriate emergency notification.

Strong outdoor alert-tone and voice-message projection
Horn orientation toward nominated school areas
Visual signalling to reinforce active alerts
Suitable receiver and antenna positioning
Wireless signal testing around site conditions
Practical controls for nominated school personnel

The emergency communication workflow

The solution: designed around the school’s emergency procedures

The AARC-EVAC platform was configured around a simple operating sequence. An authorised staff member selects the required alert, the wireless command reaches the receiver equipment and the selected message is broadcast through the emergency loudspeakers while the visual indicators activate.

Select the alert

An authorised user selects evacuation, lockdown, all-clear or testing from the approved portable or fixed control.

Transmit the command

The transmitter sends the selected wireless command through the configured AARC radio network.

Select the message

The receiver and message-control equipment identifies the selected function and activates the correct recorded instruction.

Broadcast the alert

Alert tones and voice instructions are projected through the outdoor horn loudspeakers while the visual warning beacons activate.

Conclude the event

Authorised staff use the protected cancellation or all-clear procedure to conclude the active emergency event.

Technology integrated

Wireless controls, recorded messages and outdoor alert equipment

The project combines AARC-EVAC controls, message playback, directional loudspeaker coverage and visual warning equipment in a coordinated platform configured for the school’s approved terminology and operating procedures.

School communication and emergency readiness

Why this school emergency communication project matters

Emergency communication systems are not ordinary background audio. Instructions must be understandable, outdoor areas must receive appropriate notification and authorised staff must be able to activate the correct function quickly and confidently.

Communication

Clear messages reduce uncertainty

Distinct recorded instructions help staff, students and visitors understand whether they are being asked to evacuate, lock down, remain in place or resume normal school activity.

Awareness

Outdoor areas need dedicated coverage

Playgrounds, walkways, covered outdoor areas and circulation spaces require appropriate emergency notification as well as classrooms.

Operation

Staff controls must be practical

Portable and fixed controls allow the school to align system activation with nominated personnel, known locations and approved emergency procedures.

School emergency communication questions

Frequently asked questions

Practical answers about the Merrylands East Public School installation and the planning of school emergency alert and message-broadcast systems.

What is an AARC-EVAC emergency alert system?

AARC-EVAC is a wireless-linked emergency alert and message-broadcast platform. Depending on the selected configuration, it can include receiver units, message players, amplification, horn or other loudspeakers, visual beacons, wireless transmitters, antennas, repeaters and customised recorded messages.

What alert functions were configured at Merrylands East Public School?

The project included evacuation, lockdown, all-clear and testing functions, together with a protected hidden-cancel function. Four recorded audio message files were prepared around the school’s approved procedures.

How many horn loudspeakers were installed?

The project scope included eight horn loudspeakers positioned to provide strong alert-tone and recorded-message projection across nominated outdoor and circulation areas.

Why were flashing visual beacons included?

Flashing beacons provide a visual indication that an alert is active. They reinforce the audible warning in outdoor, busy or noisy areas and provide an additional method of gaining attention.

Can authorised staff use both portable and fixed controls?

Yes. The system included a portable handheld transmitter and a fixed wall-mounted activation point. Control access, labelling, storage, testing and staff procedures should be agreed with the school.

Can the emergency messages be customised?

Recorded messages can be prepared around approved site procedures, subject to the equipment configuration and project requirements. Message wording should be reviewed and authorised by the responsible school representatives before commissioning.

Does this system replace a fire alarm or certified EWIS?

No such claim should be made unless the system has been specifically designed and certified for that statutory purpose. A school emergency alert and message-broadcast system can support approved site procedures, but fire alarm, occupant warning and EWIS requirements must be confirmed separately with the relevant consultant, fire engineer and certifier.

Can Masters Voice Technology support the system after installation?

Support can include operational testing, fault diagnosis, equipment inspection, configuration review, loudspeaker testing, documentation, staff assistance and planned maintenance. Visit the TechFlow360 support page for further information.
