100% Fire Detector Testing – Avoid Any Access Disruption
S-Quad Self-Test from Trinity
Introducing S-Quad Self-Test from Trinity, powered by Honeywell technology.
The smart new way to achieve genuine 100% compliance with zero access issues and minimal disruption.
The Challenge
In every building, there are detectors that simply can’t be reached – ceiling voids, lift shafts, locked rooms, secure areas, operating theatres. These detectors are often left untested, meaning you lose 100% compliance the moment one is missed.
You can’t achieve full fire safety compliance if even one detector can’t be tested. And many aren’t – because they’re in: Ceiling voids, lift shafts, locked rooms, operating theatres, secure areas and awkward locations – how many of your fire detectors can’t be properly tested because you simply can’t access them?
S-Quad Self-Test monitors and tests every detector in all locations across your building.
- No more access barriers – test detectors anywhere using a mobile device
- Zero disruption – live system, no fire watch, 60‑second self‑tests
- True functional testing – real smoke + heat, not electronic simulation
- Full compliance – eliminate all “untestable” detectors
- Instant documentation – automatic digital test records verified via the CLSS app.
How it Works
Self-Test heats the thermistor and introduces controlled aerosol smoke, testing both heat and optical sensors in real fire-like conditions – not just electronic simulation.
- Engineer triggers tests via the CLSS mobile app
- Device heats and activates real aerosol smoke
- Heat and optical sensors are fully tested
- Chamber automatically clears and self-verifies
- Bluetooth proximity confirms visual inspection
- Instant digital compliance records
Engineering Innovation You Can Trust
Our S-Quad Self-Test series uses dual microprocessors and Bluetooth Low Energy technology to perform authentic, repeatable functional testing. The patented design ensures accurate smoke/heat testing and automatic chamber clearing to keep detection pathways unobstructed.
- EN54 approved and LPCB certified
- Fully compliant with BS5839-1 testing standards
- Supports up to four functional tests per year
- Compatible with Vigilon and Compact Plus panel
