One Pendant. Real Protection.
The CheckMate SOS combines an emergency panic button, automatic fall detection, GPS tracking, and two-way voice in a single wearable pendant. When your workers can't reach a phone, the SOS reaches us.
When workers can't reach a phone.
Falls from height, unconscious workers, sudden impacts out of earshot of the crew. A phone in a pocket doesn't help when you're pinned under equipment or lying at the bottom of a ladder.
A wearable device that calls for help — even when the worker can't.
Press the panic button for instant help, or let fall detection trigger automatically when a worker goes down. Both send GPS coordinates and open a two-way voice channel through the pendant itself.
Most apps send a notification. We take action.
Other tools rely on push notifications and hope someone's watching. The SOS pendant connects directly to ProTELEC's Five Diamond ULC-certified monitoring centre. Live operators respond in under 60 seconds — through the pendant itself, hands-free.
Four layers of protection in one device.
The SOS pendant packs four critical safety capabilities into a single wearable device. No smartphone required, no apps to install, no training needed — just wear it and go.
Everything Built In. Nothing Extra Needed.
Worn as a pendant or clipped to a belt, the SOS is always within reach — and works even when the worker isn't conscious. No smartphone required.
Emergency Panic Button
Press and hold to immediately alert our monitoring centre. GPS and two-way voice activate simultaneously.
Automatic Fall Detection
Three sensor types analyze 190+ parameters. Detects real falls, filters out crouching and false positives.
GPS Location Tracking
Precise coordinates with every alert. Responders know exactly where to go — no guessing.
Two-Way Voice

No Phone Required
Standalone cellular device. Works independently — no smartphone, no app, no Bluetooth pairing needed.
Works When Unconscious
Fall detection triggers automatically. Even if incapacitated, the SOS sends the alert and opens voice communication.
Custom Escalation
Your emergency contacts, your procedures. Define exactly who gets called and in what order.

Need the SOS Pendant Plus the App?

Do workers need a smartphone to use the SOS pendant?
No. The SOS is a standalone cellular device with its own SIM card and connectivity. It works completely independently — no smartphone, no app, no Bluetooth pairing required.
How does automatic fall detection work?
The SOS pendant uses three sensor types — accelerometer, gyroscope, and barometric pressure sensor — to analyze over 190 parameters in real time. This multi-sensor approach detects actual falls while filtering out normal movements like crouching, bending, or setting down the device.
What happens if the worker is unconscious after a fall?
Fall detection triggers automatically — no worker input needed. The pendant sends GPS coordinates and opens a two-way voice channel. If the operator gets no verbal response, they immediately begin emergency dispatch using your custom escalation procedures.
Can the SOS pendant work alongside the Safe Alone app?
Yes. Both the SOS pendant and Safe Alone app route to the same monitoring centre and appear on the same management dashboard. Many organizations use the app for most workers and add SOS pendants for high-risk roles.
What legal obligations does the SOS help meet?
The SOS pendant helps organizations meet provincial lone worker safety requirements across Canada, including Alberta's OHS regulations for working alone. It also supports compliance with Bill C-45, which holds organizations criminally liable for failing to ensure workplace safety. Every alert is fully documented for audit purposes.
How long does the battery last?
The SOS pendant is designed for full-shift use. Battery life varies based on usage patterns and cellular signal strength. The device provides low-battery alerts so workers and supervisors know when charging is needed.
