Predictika · Fire dampers for air duct systems

An AI sales agent's fire damper order, checked before it goes out

An AI sales agent prepares an order for round fire dampers from a public product data sheet, with a casing, a release device, accessories, an installation method and operating conditions. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the data sheet and returns a verdict, every reason and the figures it computed.

Scope: TROX FKR-EU round fire dampers, nominal sizes 315 to 800 mm: casing, release device and actuators, accessories, installation method and operating limits. See everything this validator covers

This validator models orders for the FKR-EU fire damper, not just the scenarios shown below.

  • Casing and sizes — spigot or flanged casing (550 mm or 495 mm long), the nine nominal sizes from 315 to 800 mm, and a casing length stated on the order is compared with the data sheet.
  • Release device and accessories — fusible link or spring return actuator or explosion-proof actuator, the 95 °C release for warm air systems only, limit switches for fusible link versions, network modules with the 24 V Belimo actuator, the TQ installation kit for the spigot design only, and the ODA construction with a spring return actuator and mortar installation.
  • Operating conditions — upstream velocity limits by construction (8, 12 or 10 m/s), differential pressure up to 2,000 Pa, air temperature from -20 to 50 °C, and explosion-proof actuators in explosive atmospheres.

Any FKR-EU order that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (TROX publishes no list prices, so this validator produces no price build-up or line-item quote), other TROX damper types, fire resistance classes for each wall construction, minimum distances and the full list of permitted wall and ceiling types. Assumptions: the data sheet was read through summarising fetches, so only rules that matched across reads are used; the approval for dry mortarless installation in solid masonry and for a 95 °C release with an actuator are this model's cautious readings of what the data sheet lists, not stated TROX prohibitions.

The AI sales agentBuilds the fire damper order from the conversation and says it is ready.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
An accessory that only one casing accepts: the TQ kit on spigot dampersOnly with care
The kit depends on the casing on another field, so it needs a cross-field rule, and every accessory adds another.		The casing and the accessory travel in one request and the combination is checked on every call.
Limits that depend on the release device: velocity 8, 12 or 10 m/sOnly with care
Each construction has its own limit, so each needs its own comparison that must be kept in step with the data sheet.		The release device and the velocity are in one request and the limit is looked up and checked every time.
A network module that needs one actuator make and voltageOnly with workarounds
The condition spans three fields (release, make, voltage), so it needs a compound rule that interacts with the others.		All three fields are in the same request and the combination is checked with the rest.
A construction that needs both an actuator and a mortar installation (ODA)Only with workarounds
Two dependencies on different fields have to be tied to one option, and a missing match is often caught only at the end.		All items are in one request and every dependency is checked together.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the order is saved or a step is completed, so a rep often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

  

  

    
What this validator catches: findings from its test cases
Click to expand
    
Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the quote; approval findings need a person to sign off; everything else is computed.

    
1Nominal size 600 mm is not offered; the data sheet gives 315, 355, 400, 450, 500, 560, 630, 710 and 800 mm.
2The quote states a casing length of 550 mm; the data sheet gives 495 mm for the selected casing.
3The square installation kit (TQ) is for the spigot design only; it cannot be combined with the flanged (FL) casing.
4Dry mortarless installation uses the square installation kit (TQ); the quote has none.
5The data sheet lists dry mortarless installation for lightweight metal-stud, timber stud and solid timber constructions; a solid masonry wall is not listed, so a person should confirm it.
6The ODA (outdoor air, insulated) construction is available only with a spring return actuator.
7The ODA construction is suitable only for mortar-based installation with perimeter mortar infill.
8Limit switches (Z00 to Z03) are for fusible link versions; this damper has a spring return actuator.
9The TROXNETCOM modules are offered only with the 24 V Belimo spring return actuator.
10The 95 C release temperature is for warm air ventilation systems only.
11The 95 C release is listed for the fusible link; the spring return actuator releases at 72 C, so a person should confirm this combination.
12In areas with potentially explosive atmospheres the damper needs an explosion-proof actuator.
13The upstream velocity is 9 m/s; this construction allows at most 8 m/s.
14The upstream velocity is 11 m/s; this construction allows at most 10 m/s.
15The differential pressure is 2,100 Pa; the data sheet gives up to 2,000 Pa.
16The air temperature is 55 C; the data sheet gives -20 to 50 C.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares an order for round fire dampers from a public product data sheet, with a casing, a release device, accessories, an installation method and operating conditions. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the data sheet and returns a verdict, every reason and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote 8 FKR-EU fire dampers of nominal size 500 mm with a spigot casing, with a spring return actuator (Siemens, 230 V). The quote states a casing length of 550 mm. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with three findings, all in one answer. Limit switches (Z00 to Z03) are for fusible link versions; this damper has a spring return actuator. The TROXNETCOM modules are offered only with the 24 V Belimo spring return actuator. The upstream velocity is 13 m/s; this construction allows at most 12 m/s.
    6. 
      
  6. The validator returned three blocking findings in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the quote are checked against each other.
    7. 
      
  7. What this shows: for a network module that needs one actuator make and voltage, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the limit switches to no and the upstream velocity to 11 m/s.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Still blocked, with one finding, all in one answer. The TROXNETCOM modules are offered only with the 24 V Belimo spring return actuator.
    12. 
      
  12. Two findings cleared. Still blocking: network module needs a 24 V Belimo actuator.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the actuator make to belimo and the actuator voltage to 24.
    15. 
      
  15. It calls the validator once more.
    16. 
      
  16. This time the validator clears it.
    17. 
      
  17. The earlier finding is cleared, and the validator's figure matches the quote.
    18. 
      
  18. Three problems caught in one call, fixed in two passes, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
