Overview
A State School in outer Sydney having some students with mobility, cognitive, and medical needs, implemented a wireless disabled toilet emergency alarm system to significantly improve student safety and staff emergency responsiveness.
The school sought a modern, cost-effective, non-invasive safety solution that avoided major building modifications while delivering fast, reliable emergency alerts across all student toilets.
1. Background
The school identified an urgent need to enhance safety in student toilets, especially for students with disabilities, injuries, autism, epilepsy, and medical conditions requiring quick assistance.
A wireless system was requested due to the difficulty and expense to run cables from buildings that were isolated from each other. A wireless system was also preferred because it could be quickly installed without time consuming approvals, construction work, or disruption to normal school activities.
2. Key Safety Problems
The school aimed to eliminate predictable and previously experienced risks, including:
- Students with seizure conditions collapsing in toilets without a way to alert staff
- Students experiencing bullying, distress, or entrapment in stalls
- No centralised system for staff to detect or manage emergencies
- Infeasibility of installing a wired system due to high cost and building constraints
A wireless emergency call system emerged as the most practical and cost-efficient solution.
3. Project Objectives
The school established clear goals:
- Equip all student toilets with accessible, easy-to-use emergency call-points
- Ensure high reliability, hygiene suitability, and anti-tamper design
- Enable instant alert notifications in the administration office
- Extend alarm coverage to the sick bay and first-aid/recovery room
- Avoid structural modifications and minimise installation costs
- Provide a system suitable for all students, including those with special needs
4. Solution Description
4.1 System Components
- Wireless Emergency Call-Points
Installed in all student toilets and the sick bay, each call-point wired to an over-door light and buzzer unit for local alerting. - Central Wireless Annunciator with Tone Generator
Located in the administration office, displaying toilet location and emitting a loud adjustable chime. Additional Annunciators could also be deployed if required. - Optional Portable Pager
Due to planned extended system functionality some Portable Alphanumeric Pagers were included for mobile alert visibility by the Principal and senior staff.
- System Easily Expended for Future Requirements
Additional pagers, call points and remote pendants could be included as the need prevailed. These are delivered preprogrammed and ready to use.
5. Implementation Process
5.1 Consultation & Compliance
The school consulted with:
- NSW Department of Education Facilities Team
- School Executive & Management
- P&C Committee
5.2 System Specifications
- Wireless call-points powered via 3.3V battery or optional 12V external supply
- Battery life target: ~5,000 transmissions, 5-year standby, 10-year shelf life
- Protected UHF hospital-grade wireless band
- Wireless Range extenders available if required to suit future system expansion
- System fully independent of Wi-Fi, internet, or other communication networks
- Multiple active calls displayed simultaneously until cancelled
- Scalable for future expansion without reprogramming
5.3 Installation Features
- No drilling into tiles; non-invasive adhesive anchors used
- All devices fitted with CR2032 replaceable batteries
- Call-points designed to meet IP64 splashproof standards
5.4 Staff & Student Training
- Admin staff trained to recognise and respond to office and Pager alerts
- First-aid staff conducted emergency response drills
- Students with disabilities taught how and when to activate alarms
6. Results & Outcomes
6.1 Significant Improvement in Student Safety
- Students respected the new emergency system with guidance and signage
- Parents expressed strong approval, particularly families of special-needs students
- Increased confidence in the school’s emergency response procedures
6.2 Faster Response Times
- Average response reduced from approx. 10-15 minutes to under 90 seconds
- Clear Annunciator Display and alert tones improved coordination and speed
6.3 Cost & Efficiency Benefits
- Wireless installation saved approximately 65% cost compared to wired solutions
- No structural changes meant no delays, approvals, or disruption
7. Challenges Noted
- Occasional non-emergency activations due to student curiosity (resolved through education)
- After site testing no wireless repeaters were required
- Battery maintenance integrated into the school’s annual maintenance cycle
8. Conclusion
The NSW State School’s wireless toilet alarm system significantly enhanced student safety, emergency preparedness, and peace of mind for families and staff.
Its low-cost, fast installation and high reliability make it an ideal solution for schools needing improved toilet and hygiene-area safety without complex infrastructure upgrades.
The successful deployment is now shaping future to install emergency call-points in:
- Junior playground
- PE building
- Sports change rooms
- General outdoor and indoor high-risk areas
