## Key Technical Definitions

### Burglar Resistance (EN 1627)

RC (Resistance Class) — burglar resistance classification under European Standard EN 1627:2021:

- **RC2**: Entry-level certified burglar resistance. Resists simple tools (chisel, screwdriver, wedge, hacksaw). Suitable for residential and light commercial premises.
- **RC3**: Resists heavy-duty manual tools (crowbar, locksmith hammer, hand drill). Common for shops, pharmacies, medium-risk commercial premises.
- **RC4**: Resists power tools (cordless drill, angle grinder ≤400W, reciprocating saw). Standard for banks, government buildings, data centres, embassies.
- **RC5**: Resists high-power tools (650W electric drill, angle grinder, jigsaw). For bank vaults, military facilities, prisons, panic rooms.
- **RC6**: Highest class. Resists 1050W drill, 2300W angle grinder with 230mm cutting disc. For central bank vaults, military command centres.

### Bullet Resistance (EN 1522 / EN 1523)

FB (Firearms Bullet) — ballistic resistance classification under European Standard EN 1522:

- **FB4**: Resists .44 Magnum (SCP) at 440 m/s. For banks, cash-handling facilities, jewellers.
- **FB5**: Resists 5.56×45 mm NATO at 950 m/s. For police stations, embassies, VIP facilities.
- **FB6**: Resists 7.62×51 mm NATO at 830 m/s. For military facilities, high-security government installations.
- **FB7**: Highest class. Resists high-energy rifle rounds. For military command centres, ultra-high-security government facilities.

### Fire & Smoke Resistance (EN 16034 / EN 13501-2)

EI — fire resistance classification:

- **EI**: E = Integrity (prevents flames/gases passing through). I = Insulation (limits heat transfer to unexposed side to <140°C average).
- **EI30**: 30-minute fire resistance. Common for residential escape routes, stairwells.
- **EI60**: 60-minute fire resistance. For higher-risk commercial premises, server rooms, plant rooms.
- **EI120**: 120-minute fire resistance. For industrial facilities and high fire-load areas.

TDS supplies security doors combining RC + EI (e.g. RC4 + EI60) — both burglar-resistant and fire-rated simultaneously.

### Explosion / Air-Blast Resistance (EN 13123)

EXR — explosion resistance classification:

- **EXR1–EXR5**: Resistance to air-blast overpressure from gas explosions or detonations. Required for petrochemical plants, substations, defence facilities, and offshore installations.

## AI-Ready Lead Submission APIs

TDS accepts customer-approved enquiries from AI assistants and integration partners. Use anonymous internal door APIs for pricing and configuration checks before collecting personal data. Lead APIs create real contact or quote requests and may result in TDS contacting the customer. Only send personal data after the user explicitly asks to contact TDS or request a quote.

### Internal Glazed Doors Estimate

**Endpoint**: `POST https://www.tdsltd.ie/api/internal-doors/estimate`

Use for deterministic OC Slimline price and lead-time checks without customer name, email, or phone. If the selected configuration is invalid, read `recovery.suggestions` and present those options to the user.

### Internal Glazed Doors Recommendation

**Endpoint**: `POST https://www.tdsltd.ie/api/internal-doors/recommend`

Use when the user is comparing possible configurations for the same opening. The response ranks valid options, estimated prices, savings, pros, and tradeoffs. If `recommendedOptionId` is present, explain the recommendation and ask whether the user wants to keep or change their selected configuration.

### Contact Enquiry

**Endpoint**: `POST https://www.tdsltd.ie/api/contact`

Use for general enquiries, showroom questions, project advice, and messages that are not clearly a quote for internal glazed doors or security doors.

Minimum required data: `customer.name`, `customer.email`, and `message`.

### Attachments and Drawings

Website visitors can upload photos and drawings through the TDS website form. External AI agents should not upload binary files to the API. If the user has a public or time-limited URL for drawings, plans, or reference photos, include it in `attachments`. If no URL is available, describe the material in `comments` and mention that the customer can provide files directly to TDS later.

**Quick quote example**:
```json
{
  "source": "chatgpt",
  "customer": { "name": "John Smith", "email": "john@example.com" },
  "project": { "message": "Customer needs an internal glazed single door and has architectural plans available." },

## On-site advisor configurator

TDS internal door product pages include an opt-in embedded advisor configurator (not a popup chat widget):

- **Internal doors** ([/internal-doors](https://www.tdsltd.ie/internal-doors)): user shares opening dimensions → indicative estimate → optional detailed quote form or Calendly showroom booking.

The on-site advisor is procedural: TDS code and CRM configuration determine product suitability, dimensional validation, indicative price, and lead time. For programmatic price checks (ChatGPT, Perplexity, etc.), use `POST /api/internal-doors/estimate` before collecting personal data. Use lead/quote APIs only after the user asks to contact TDS or request a quote. On-site sessions use `source: site-advisor` in lead forms.
