Why this decision matters
Comparing hardware prices alone can hide different labour, compatibility and recurring-service assumptions.
Work through the actual task
- Compare exact radio range/family, supervision features and included devices.
- Identify communicator, repeaters, subscriptions and battery service assumptions.
- Ask for missing items in writing and keep the accepted scope with your receipt.
Questions and evidence to request
| Question | Useful evidence in the scope |
|---|---|
| Which devices and regions/radio families does the panel support? | The full panel, device-family and regional model compatibility schedule. |
| Have links been checked at final mounting positions? | A supported link test at the actual final mounting positions. |
| What changes when doors close or large metal fixtures are installed? | A realistic operating-condition check and any supported repeater requirement. |
| Who receives battery/link warnings and arranges maintenance? | A warning recipient and practical approved-battery/service process. |
| Which remote features need broadband, mobile service or a subscription? | A function-by-function communication/subscription dependency and cost list. |
Worked example
A wireless package lists only a panel and sensor count. This is a hypothetical example, not a completed customer installation.
The useful evidence at the end of this example is: A compatible-device and recurring-cost schedule.
Limits and follow-up
Do not assume wireless devices from different ranges work together. Obtain a written compatible device list for the specific panel and firmware.
If the relevant check cannot be completed, record what remains uncertain and who will resolve it before work or sign-off proceeds.
