Lamp driver module

Table of Contents

NOTE: The LDM begins annunciation of circuits on the module installed directly after the CPU-5000. To ensure full employment of LDM

points, mount the modules that need lamp driver annunciation in the CPU row first, then in the second row, etc. Modules with circuits that

are not to be annunciated by the LDM-32 should be installed further down in the cabinet.

B.1 Capabilities

When installed with a System 5000, the LDM Series modules can annunciate the status of initiating and notification circuits, relays, and

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

Optional System 5000 plug in Modules

•

IZM-8 - Initiating Device Circuits (alarm and trouble)

•

AIM-200 Zones (alarm and trouble)

•

ICM-4/ICE-4 - Notification Appliance Circuits (trouble)

•

CRM-4/CRE-4 - Control Relay Modules

•

TCM-2/TCM-4 - Time Control Modules

•

VCM-4/VCE-4

•

DCM-4

System Control Switches

•

Acknowledge

•

Signal Silence

•

System Reset

•

Activate selected system outputs (notification circuits, relays)

Trouble Indication

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

is supervised by the System 5000. Loss of communication results in System Trouble and Module Failure indications at the CPU.

Lamp/LED Driver Operation

Lamp Driver outputs do not latch - they track or follow the status of each zone/point that they are assigned to annunciate. Table B.1

defines the ON status of each Lamp Driver output.

Software Required

For the LDM to function properly, the CPU must be operating under ROM1-5000 Part Number 73085 (or higher).

Programming for Remote Annunciation

After complete installation, the LDM must be programmed into the System 5000 before it will function. Program the LDM as if it were

an annunciator. Refer to the System 5000 Programming Manual, Document 15584.

B.2 Installation Requirements

The EIA-485 circuit that communicates with the LDM must be connected to the CPU as illustrated below. The CPU must be Revision D

or greater. The revision level of the CPU is marked on a label affixed to the upper board.
