Key Takeaways
- Scenario 1473 is fire-extinguisher / life-safety tag MMS — not scaffold cards, meter dials, hazmat bags, LOTO, night keys, storm claims, or closeout selfies.
- A cropped tag and asset id are the payload. Do not MMS the lobby, staff faces, or neighboring suites.
- Read MMS and “we attended” SMS must not share a radio with portal OTP or a “renew the contract” blast.
- Priced by devices and SMS send volume. You use your own phone and operator SMS credit. Free is 1 / 300 / 300. Developer is 25,000 SMS per year.
- Operator MMS is usually dearer than SMS. Budget monthly inspection routes separately.
- REST attachment fields live in Developer Center — not a CodeCanyon life-safety add-on. MCP, if you use it, is only a REST wrapper.
Summary
Scenario 1473 is field MMS for fire-extinguisher inspection tags. The CMMS owns the asset id. The Android sends a cropped tag so the desk can close the monthly route. Priced by devices and SMS send volume. You use your own phone and operator SMS credit.
If the only proof of the punch is an MMS the APN dropped, you do not have an inspection. You have another verbal “it was in date.”
