01
Start with what the building permits.
A building under construction, an open shop and an occupied property offer different possibilities. Record ducts, usable routes, finishes to preserve and intervention periods. A line on a drawing is not an available route: it must be installed, labelled and maintained. Equipment price alone cannot compare proposals.
Separate detector-to-panel communication from panel-to-recipient transmission. Wired detectors can use cellular reporting, while wireless detectors do not mean the whole system lacks fixed power. Request both chains with intermediate devices and their requirements. That diagram and its tests reveal the actual dependencies.
02
Compare evidence, not labels.
Scroll the table horizontally to compare all three columns.
| Approach | Document | What is insufficient |
|---|---|---|
| Wired | Routes, cable, power, exact inputs/bus and end-to-end tests. | An unidentified existing cable or continuity alone. |
| Wireless | Supported family, on-site link qualification and battery maintenance. | Open-space range or a bench test. |
| Hybrid | Exact panel/expander/detector combinations and retained equipment. | A shared brand or “universal” in a quotation. |
| Remote reporting | Channel, recipient, any subscription and receipt evidence. | A connected icon without verified receipt. |
03
Four records for comparing complete proposals.
Points and operation
List openings, spaces and occupancy periods with stable identifiers. State separately controlled areas, users and planned expansion. Do not put access codes, detailed personal routines or sensitive plans in a public enquiry; arrange secure handover to the appointed professional.
Connection medium
For each point, identify a known cable, a route to create or a radio link to qualify. Record obstacles and foreseeable layout changes. Retain proposed expander and detector references: similar frequency or connectors do not establish supported protocol or functions.
Power and follow-up
List power supplies, backup batteries and device cells. Ask for runtime assumptions, fault reporting and replacement ownership. Connection type does not eliminate maintenance. An estimate without references, loads and use conditions remains an assumption, not a commitment.
Acceptance and complete cost
Separate equipment, installation, making good, tests, training and any subscriptions. Define each point’s evidence: identifier, link, event and reporting. Compare proposals against the same unknowns and exclusions. Faster installation may require different maintenance access; identify it before choosing.
04
Eight proposed points are not eight accepted points.
ILLUSTRATIVE EXAMPLE
Fictional refurbishment: six retained wired points and two new wireless points, eight to qualify. No product or customer installation is described. The observations are invented to explain the decision.
Retain the failed result
P-08 communicates during the demonstration but its link is unstable under an agreed use condition. It remains “link needs review”. A photograph of momentary connectivity does not close the issue, and the other seven points do not validate the eighth.
Compare two documented corrections
The integrator assesses another wireless position or a feasible wired route with the required compatible equipment. These are proposals, not successful fixes. Keep the item open until the authorised change and retest under agreed conditions; do not remove the point from scope to improve the result.
Check the other chain separately
In a separate test, P-07 appears in the panel log but recipient receipt is unconfirmed. Record observed detection and unaccepted reporting separately. Neither a local log nor a “sent” button establishes remote receipt or an intervention.
Documentary example: no live trigger, radio adjustment or system change. It guarantees neither prevention of intrusion nor response time.
05
Accept the delivered function, not just the hardware.
An identified test for each point
The professional plans authorised tests and records location, conditions, result and exceptions. Communication, detection, power and warning are different checks. An indicator or signal value alone does not show that the intended event reaches the right place.
Actually verified recipients
Identify who receives and confirms the test, coordinating any connected monitoring centre. Record channels and dependencies. Do not trigger a live alarm merely to try an app; notification, human acknowledgement and an on-site response are different outcomes.
Operation that can be handed over
Hand over inventory, references, labels, results and agreed instructions. Separate operator and maintainer access and transfer secrets securely. Identify who handles faults or layout changes; neither “wireless” nor a product warranty defines those responsibilities.
06
Request an architecture and its open issues, not just a kit.
Provide a non-sensitive premises brief, point counts by purpose and known routing conditions. Request separate panel, expander, detector, control, warning, transmission and power lines. Include open questions and test scope. Inovexia helps document selection; design, installation and operating commitments must be agreed with the relevant provider. Retained equipment needs its exact reference and compatibility evidence, not merely a brand name.
07
Questions that prevent shortcuts.
Does wireless mean Wi-Fi?
No. Identify the device protocol and panel network connection separately. A wireless detector is not automatically compatible with Wi-Fi access points or another alarm family.
Can existing wiring always be retained?
Not without identification and checks. Condition, route, power and interface must suit the proposed device. Continuity alone does not establish all those conditions.
Does open-space range guarantee an indoor result?
No. Require on-site qualification under actual use conditions. No universal factor converts advertised range into a guaranteed distance through walls.
Are two devices of the same brand necessarily compatible?
No. Generation, protocol, expander and version matter. Manufacturer documentation must confirm the exact combination; verify a replacement as a new selection.
Does a notification imply monitored response?
No. Phone receipt, human handling and intervention are distinct services. Ask who does what under which agreement; a communicator alone includes none of those commitments.
