# Ademco format

Reference Ademco Contact ID fields, DC-09 packet structure, and event codes.

Command Centre transmits alarm events in the **Ademco Contact ID** format over both Analog (PSTN dialler) and IP (DC-09) transports. This page is the format reference. For how to set up monitoring and diallers, see [Alarm Transmission - Monitoring](/knowledge-hub/products/cc-software/configure/alarm-transmission/alarm-transmission-monitoring.md).

### Alarm Dialler format (PSTN)

The Alarm Dialler (Dialer in the USA) is a component that uses an RS232 (serial) port to connect to a PSTN dialler and send messages using **ADEMCO Contact ID**, an industry standard across the world since 1999.

The format of the message is:

```
ACCT  MT  Q XYZ  GG  CCC
```

| Field    | Meaning                                                                                                                                                                                                                                 |
| -------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **ACCT** | 4-digit account number (0-9, B-F). Set in either the System Properties or in the Alarm Zone itself.                                                                                                                                     |
| **MT**   | Message Type. A 2-digit sequence identifying the Contact ID message to the receiver. Transmitted as either **18** (preferred) or **98** (optional). New receiver implementations accept either; some older receivers may not accept 98. |
| **Q**    | Event qualifier: **1** = New Event or Opening; **3** = New Restore or Closing; **6** = Previously reported condition still present (status report).                                                                                     |
| **XYZ**  | Event code (3 hex digits, 0-9, B-F). Decided by the event type selected at the Input Properties. See the addendum table below.                                                                                                          |
| **GG**   | Group or Partition number (2 hex digits, 0-9, B-F). This is the Alarm Zone in Command Centre. Use **00** to indicate no specific group or partition applies.                                                                            |
| **CCC**  | Zone number (event reports) or User # (open/close reports), 3 hex digits (0-9, B-F). Use **000** to indicate no specific zone or user applies.                                                                                          |

### IP Alarm Transmitter format (DC-09 packet)

The IP Alarm Transmitter sends messages directly from the controller to a monitoring station over TCP/IP instead of a phone line. It has two protocol options, **CSV** and **DC-09**. The following explains how the DC-09 message is composed and how it relates to ADEMCO Contact ID.

A controller's outgoing message, observable in the controller's debug webpage under **Parts Manager > Alarm Transmitter Part**, may look like:

```
"ADM-CID"0005L98765#001235[#001235|1423 44 777]_17:15:19,03-06-2026
"ADM-CID"0006L98765#001235[#001235|3423 44 777]_17:15:30,03-06-2026
```

The format is:

```
ID  SEQ  LLLLL  #RI  [#ACCT | Q XYZ GG CCC ] _TIME,DATE
```

The second half (between `|` and `]`, which DC-09 calls the **DATA**) is almost identical to the Alarm Dialler format, except there is **no MT**. The ACCT is sent as **6 digits**, so an ACCT of 1235 in Command Centre is padded to **001235**.

Aside from time and date, there are four new components: **ID, SEQ, LLLLL, RI**:

| Field     | Meaning                                                                                                                                                                  |
| --------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| **ID**    | The format, always `"ADM-CID"` within Command Centre. Tells the receiver we are using ADEMCO Contact ID format in the DATA.                                              |
| **SEQ**   | The sequence of messages (for example 0005, then 0006 on the next message).                                                                                              |
| **LLLLL** | Line Card. In Command Centre this is called the **Prefix**. For American monitoring stations this is typically known as **DNIS**, despite that being an antiquated term. |
| **RI**    | Receiver ID. The field that causes the most confusion.                                                                                                                   |

### Receiver ID behaviour changed by version

RI is intended to be an ID for the device sending the message (a panel ID, or a Transmitter ID as Command Centre calls it). However, Command Centre versions **v8.70.2078+ (MR3+), v8.80.1025+ (MR1+) and v8.90+** behave differently since the Prefix field was added:

* If **Prefix is set to 0** then the old behaviour remains: the **Transmitter ID** is sent in this field.
* If **Prefix is populated with something other than 0** then the **6-digit ACCT** is sent (as in the two examples above).

How it looks in the Configuration Client:

> **Note:** The Gallagher IP Alarm Receiver software is still able to receive messages, as long as the 6-digit value of ACCT is configured in the field the receiver software calls **Transmitter ID**.

### Addendum: XYZ event code list

The following is the **internationally accepted** Contact ID event code list. Note that this is the standard list, **not necessarily the event Command Centre will transmit**.

| XYZ | Name                                            | Type          | Description                                                                                                                                                           |

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://help.security.gallagher.com/knowledge-hub/products/cc-software/configure/alarm-transmission/alarm-transmission-ademco-format.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
