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.

  • Evacuation, lockdown, all-clear and test functions
  • Four school-specific recorded audio messages
  • Protected hidden-cancel operation
  • Portable handheld control for mobile staff
  • Fixed wall-mounted activation point
  • Configuration, testing and staff handover

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

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.

Outdoor alert equipment

Horn loudspeakers and visual beacons

Directional horns project alert tones and recorded instructions toward nominated outdoor areas, while visual beacons reinforce the active alert where noise, distance or activity may affect awareness.

Project outcomes

Clearer emergency communication across the school

The completed installation gives Merrylands East Public School a coordinated way to issue distinct emergency instructions, extend audible coverage into nominated outdoor areas and reinforce active alerts with visual warning beacons.

0 Outdoor horn loudspeakers
0 Dedicated emergency messages
0 Authorised control formats
0 Coordinated wireless alert platform
01

Consistent recorded instructions

Approved evacuation, lockdown, all-clear and test messages can be broadcast consistently, reducing reliance on improvised live announcements during a stressful event.

02

Improved outdoor alert coverage

Eight directional horn loudspeakers project alert tones and voice instructions toward nominated playgrounds, walkways and circulation areas.

03

Audible and visual notification

Flashing warning beacons reinforce the audible message and improve awareness where activity, distance or background noise may affect audibility.

04

Practical staff activation

Portable handheld and fixed wall-mounted controls provide practical activation options for nominated staff while supporting controlled, authorised operation.

05

Clear separation of alert types

Separate functions help staff and students distinguish between an evacuation, lockdown, all-clear notification and planned system test.

06

Tested, commissioned and handed over

The system was configured and operationally tested, with staff handover supporting ongoing use, routine testing and future maintenance.

The overall result

A purpose-built emergency communication workflow for the school

The project brings together wireless activation, recorded messaging, directional loudspeaker coverage and visual warning equipment in one practical system aligned with the school’s nominated emergency 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.
