E.1 Capabilities

When installed with an AFP-200, LDM Series modules can annunciate the status of 99 software zones and several system control func-

tions. Each lamp driver output is automatically assigned to one and only one system I/O point:

•

Software Zones

– Intelligent Detectors

– MMX Monitor Modules

– CMX Control Modules

– BGX Addressable Manual Pull Stations

•

System Control Switches

– Acknowledge

– Signal Silence

– System Reset

– Drill

E.2 Trouble Indication

Communication between the AFP-200 and the LDMs is accomplished over a two-wire EIA-485 serial communication bus. The EIA-485

is supervised by the AFP-200. Loss of communication results in System Trouble and Annunciator 1 (2) No Answer message on the

panel's 80 character LCD display.

E.3 Lamp/LED Driver Operation

Lamp Driver outputs do not latch - they track or follow the status of those point they are programmed to annunciate. Table E.1 outlines

the annunciation of the various zones and functions.

E.4 Programming for Remote Annunciation

After complete installation, the LDM must be programmed into the AFP-200 before it will function. Program the LDM as if it were an

ACS annunciator. Refer to the AFP-200 Programming Manual, Document 15511.

E.5 Installation Requirements

Regulated power (24 VDC) and the EIA-485 circuit that communicates with the LDMs must be connected to the AFP-200 as illustrated

below.

For more information on annunciator operation and FACP programming under various specific applications, refer to the AFP-200 docu-

ments referenced in Section 1.3, "Related Documentation", on page 7.
