Predictika · Exit device door-opening specifications

An AI sales agent's exit device specification, checked before it goes out

An AI sales agent prepares a specification for a Von Duprin 98/99 Series exit device with its length, door width, fire rating, dogging, finish and handing. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the catalog's published rules and returns a verdict, every reason and the figures it computed.

Scope: Von Duprin 98/99 Series exit devices: device type, length for the door width, fire rating, dogging, finish and handing options. See everything this validator covers

This validator models Von Duprin 98/99 Series exit device specifications, not just the scenarios shown below.

  • Device and door size — rim, surface vertical rod, concealed vertical rod and mortise devices; the 2 ft 2 in door size is listed only for the vertical rod types and ships without a fire label; the 3 ft device covers doors from 2 ft 4 in to 3 ft and the 4 ft device doors from 2 ft 10 in to 4 ft.
  • Fire rating and dogging — fire-rated (-F) devices have no mechanical dogging; electric latch retraction is the option catalogued for fire mortise and vertical rod devices.
  • Finish and handing — finishes US15 and US32D are available with the 98 Series only; rim devices with special dogging, a double cylinder or a signal switch, and mortise devices with a double cylinder or a signal switch, are handed and need a hand on the quote. The device length fitted to the door is also compared with the door width the quote states.

Any exit device specification that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (no price list is modeled, so this validator produces no price build-up or line-item quote), trims and lever functions, three-point latching, the other Von Duprin and Allegion product lines, door thickness and the full finish list.

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
A device length that does not fit the door widthOnly with care
Each length has its own door-width range, so each needs its own validation rule and limits.		The length and the door width are in one request and compared on every call.
Fire-rated devices with mechanical doggingOnly with care
A rule that depends on one choice on one line and another on a different line; it works, but must be maintained with every new option.		Every choice is in one request, so the conflict is found whichever order the choices arrive in.
Finishes that exist for one series onlyOnly with care
A product rule per finish and series, maintained as the finish list changes.		The series and the finish are checked together on every call.
Options that make a device handedOnly with workarounds
The need for a hand depends on the device type and on several options at once, so it takes cross-line rules that interact with the rest.		Device type, options and hand are in one request and checked together.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the specification 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.

    
1The 2 ft 2 in door size is listed only for surface and concealed vertical rod devices, not for rim or mortise devices.
2The 2 ft 2 in door size is shipped less the UL label, so it cannot be quoted as a fire-rated device.
3The door is 37 inches wide, wider than the 36 inch maximum for the selected device length.
4The door is 27 inches wide, narrower than the 28 inch minimum for the selected device length.
5The door is 33 inches wide, narrower than the 34 inch minimum for the selected device length.
6The door is 49 inches wide, wider than the 48 inch maximum for the selected device length.
7The door is 30 inches wide, wider than the 26 inch maximum for the selected device length.
8Fire-rated (-F) devices have no mechanical dogging; electric latch retraction is the option offered on fire mortise and vertical rod devices.
9Finishes US15 and US32D are available with the 98 Series only.
10With special dogging, a double cylinder or a signal switch the device is handed, so the quote needs a hand; the quote gives none.
11The quote states that the device fits doors up to 48 inches, but the selected device length fits doors up to 36 inches.
12The quote states that the device fits doors up to 36 inches, but the selected device length fits doors up to 26 inches.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares a specification for a Von Duprin 98/99 Series exit device with its length, door width, fire rating, dogging, finish and handing. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the catalog's published rules 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 specify one Von Duprin 99 Series mortise exit device, 2 ft 2 in door size, for a door 26 inches wide. The specification states that the device fits doors up to 26 inches. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with two findings, all in one answer. The 2 ft 2 in door size is listed only for surface and concealed vertical rod devices, not for rim or mortise devices. With special dogging, a double cylinder or a signal switch the device is handed, so the quote needs a hand; the quote gives none.
    6. 
      
  6. The validator returned two 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 options that make a device handed, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the device length to 3 ft device (2 ft 4 in to 3 ft doors), the door width to 34 inches and the stated door width the device fits, as to 36 inches.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Still blocked, with one finding, all in one answer. With special dogging, a double cylinder or a signal switch the device is handed, so the quote needs a hand; the quote gives none.
    12. 
      
  12. One finding cleared; still blocked on handed option on a non-handed device.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the handing to left hand reverse.
    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. Two 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.
    19.
