Section One: Introduction to the LDM Series

The LDM Series Lamp Driver Modules, which consist of the LDM-32 master and LDM-E32

expander modules, are used to provide an interface to a custom graphic annunciator. The

master module provides power and control for a maximum of three expander modules.

The LDM-32 and LDM-E32 have output connectors which are used to drive lamps or LEDs

and input connectors which are used for remote switch functions.

The LDM Series Lamp Driver Modules may be connected to fire alarm control panels

(FACP) to provide remote annunciation of the following:

• General system status:

ü General Alarm

ü General Trouble

ü General supervisory

ü Notification Appliance Circuit (NAC) output status

ü Municipal tie status

ü System silence

ü Alarm relay status

• Alarm and trouble status of zones or individual points

• Alarm only status of zones or individual points

The LDM Series Modules also interface to remote control switches which may be used to

provide:

• System reset

• System silence

• System acknowledge

• Temporary activation of NAC outputs

• Alarm relay activation

• Other control functions

The LDM Series Modules interface to the host fire alarm control panel via an EIA-485

communications bus circuit. A maximum of 32 LDM-32s may be connected to the power-

limited EIA-485 bus, but if other types of devices are also connected to the EIA-485 bus,

the maximum number of LDM-32s must be reduced by the total of such devices. The EIA-

485 wiring distance must not exceed 6,000 feet and cannot be T-tapped. Multiple LDM-

32s may be used to annunciate duplicate information.

Power to the LDM-32s is typically provided by the host FACP and must be power-limited

regulated 24 VDC. External UL listed battery backed power supplies may also be used.

Careful consideration must be given to system battery calculations when power for the

LDM modules and lamps or LEDs is provided by the host FACP

. Refer to the specifications

in the appropriate FACP technical manual when making these calculations.

SectionTwo: LDM Features

2.1The LDM-32

The Lamp Driver Module LDM-32 has 32 alarm lamp/LED driver outputs which sink current

to system common (-) on activation. A single positive (+) voltage is required to supply total

operating power for all lamps or LEDs when all drivers are activated. The LDM-32 provides

a separate driver for system trouble and inputs for a local lamp test switch. A maximum of

16 external control switches may be wired to the LDM-32. DIP switch SW3 is used to enable

or disable the onboard piezo, enable remote switch functions, select a flashing LED function

for new alarms and troubles, and other functions. Switch SW4 is used to configure the

module to annunciate 32 alarms or 16 troubles. A green ON LINE LED flashes to indicate

ongoing communications with the host FACP. One LDM-32 supports up to 3 LDM-E32

modules. The LDM-32 is supplied with 4 standoffs and screws for mounting to a CHS-4L

chassis or custom backbox.

2.2The LDM-E32

Each LDM-E32 expander module provides 32 additional lamp/LED driver outputs from J5,

J6, J7 and J8. The expander module has a slide switch SW4 for selecting alarm or alarm

and trouble annunciation and an input for a local lamp test switch. In alarm mode, use only

one LDM-32 and one LDM-E32 for a maximum of 56 alarm indicators and 8 system status

indicators. In alarm/trouble mode, use one LDM-32 and three LDM-E32s for a maximum of

56 alarm indicators, 56 trouble indicators, 16 status indicators and 64 optional control switch

inputs. Multiple sets of LDM-32s with LDM-E32 expanders increasethe systemannunciation

capabilities beyond 56 zones or points. This is possible by various settings of address

switches SW1 and SW2 on the LDM-32 (refer to Appendices). Each LDM-E32 is supplied

with a 26 conductor expander ribbon cable, 4 standoffs and 4 screws.

2.3 Connectors on the LDM-32 and LDM-E32

J1 - Switch Matrix

Up to 16 optional external control switches and a local lamp test switch may be attached

to the LDM-32 and LDM-E32 via J1 as shown in Figure 4-10. To determine which switch

function each point will perform in a System 5000, refer to Appendix table A-1 (System

5000). Switch functions on an AM2020/AFP1010 are completely programmable.

J2 - Ribbon Cable Connection Between Master and Expander Modules to J3

A single 26 conductor ribbon cable may be connected from J2 on the LDM-32 or LDM-

E32 (see Figure 3-3) to J3 on adjacent LDM-E32s. The ribbon cable carries power,

ground and signaling from the LDM-32 to up to three LDM-E32s. The preformed cables

are supplied in fixed lengths of 24 and 48 inches.

J3 - Ribbon Cable Connection From J2

This connector supports a single 26 conductor ribbon cable from J2 of the previous

LDM-32 or LDM-E32. Refer to Figure 3-3.

J4 - Keyswitch Input

This two pin connector is provided as an input on LDM-32 and LDM-E32 modules for an

external security keyswitch. KeyswitchcontactsmustbeNormally Closed. The keyswitch

prevents unauthorized use of remote control switches wired to J1.

J5, J6, J7 and J8 - Lamp/LED Driver Outputs

Each connector provides 8 driver outputs for a total of 32 drivers on each LDM-32 and

LDM-E32. Each driver is rated for a maximum of 30 volts and a current of 100 mA. Each

bipolar Darlington open collector driver output must be current limited by an external

resistor. 8-Point Shift and Flash functions are selectable by DIP switch SW3 (refer to

Section 2.4). Lamp/LEDs may function in 'alarm only mode' or 'alarm/trouble mode' as

selected byswitch SW4. Use the charts and examples shown in Appendices A and B for

additional information.

J9 - Lamp Power/SystemTrouble

Connector J9 is located only on the LDM-32. J9 pin 1 provides 24 volts regulated power

to all lamps/LEDs used in a custom graphic annunciator. The current limit of J9 pin 1 is

dependent upon the current limits of the external power source being used. J9 pin 3 is

a driver output for system trouble indication only. J9 pin 2 connects to system common.

J10 - Relay Expander

Cables to the optional LDM-R32 Relay Expander Module which can be used to provide

up to 32 dry Form-A (normally open) contacts.

J11 - 5VDC Power

This connector is located only on the LDM-32. J11 pin 1 provides 5 volts regulated

power to all lamps/LEDs used in a custom graphic annunciator. The maximum current

available from this output is 300 mA. This current is sufficient to power the maximum

number of LEDs available with one LDM-32 and three LDM-E32s (from J5, J6, J7, J8

and one system trouble LED)

provided the current rating per LED is 2 mA.

2.4 Switches

SW1 and SW2 - Address Switches

Two rotary BCD switches, located only on the LDM-32, are used to set the LDM Series

system address. Switch SW1 represents the 'ones' position and switch SW2 represents

the 'tens' position of the address setting. In system configurations of 56 zones or less,

the switches must be set to address 01 for all LDMs in the system. For configurations

larger than 56 zones, multiple sets of LDMs are required with sequential addresses, the

first LDM starting at address 01. Each incremental setting adds 64 zones/points to the

system.

SW3 - Function DIP Switch

SW3, which is located only on the LDM-32, is used to set the annunciator functions.

Function settings include:

• Number of expanders connected

• 8-Point Shift enabled

• Receive Only communications to host FACP (no system control switches or

loss of supervision)

• Receive/Transmit communications to host FACP (system control switches plus

supervision)

• Control Switch Disable

• Piezo disable

• Flash Inhibit

Refer to Appendices A and B for additional information.

SW4 - Alarm/Trouble Mode Switch

The Alarm/Trouble mode switch is installed on the LDM-32 and LDM-E32.

The switch

setting on each expander module must match the switch setting of the associated LDM-

32.

'Alarm Only' mode causes the driver outputs to turn on only for alarm conditions per

associatedzoneorpoint atthe hostFACP. Alarm/Trouble mode causes the driver outputs

to turn on for both alarm and trouble conditions per associated zone or point at the host

FACP. Since this switch affects the assignments of connectors J5, J6, J7 and J8, make

certain to review the appendices in this manual for additional information on wiring to the

lamp/LED drivers.

TB1 - Power, Earth Ground and Supervision

Removable terminal block TB1 appears only on the LDM-32. 24 volts power-limited,

regulated, non-resettable power from the host FACP or a compatible UL listed battery

backed power supply must be connected to TB1-3 (+) and TB1-5 (-). Terminals TB1-2

(+) and TB1-4 (-) may be used to daisy chain the 24 volts to other LDMs or devices.

Earth ground must be connected to TB1-1. Terminals TB1-6 and TB1-7 provide a

supervised input which may be used to supervise local power sources or other devices.

A trouble signal is transmitted to the host FACP upon an open circuit across these

terminals. The input must be power-limited. If these terminals are not used, a jumper

must be installed.

TB2- In/Out

Removable terminal blockTB2 appears only on the LDM-32. All LDM-32s must connect

to the EIA-485 communications bus circuit for proper operation. The EIA-485 bus carries

commands and data sent between the host FACP and the LDMs. The input must be

power-limited.
