LDM-32F PN 50055:C 03/20/01
Connectors
J1 - Switch Matrix
Up to 16 optional external control switches and a local lamp test switch may
be attached to the LDM-32F and LDM-E32F via J1 as shown in Figure 16 on
page 24. In the Sensiscan 2000, the control switches may be mapped to the CPU
function switches and all input and output modules. In the MS-9200 and MS-
9600, the switches may only be used for remote Acknowledge, Reset, Drill and
Silence. External switches must be momentary type.
J2 - Ribbon Cable Connection to J3
A single 26-conductor ribbon cable may be connected from J2 on the LDM-
32F or LDM-E32F (see Figure 6 on page 18) to J3 on adjacent LDM-E32Fs.
The ribbon cable carries power, ground and signaling from the master module
to up to three expander modules. 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-32F or LDM-E32F. Refer to Figure 6 on page 18.
J4 - Key Switch Input
This two pin connector is provided as an input on LDM-32F and LDM-E32F
modules for an external security key switch. Key switch contacts must be
Normally Closed. The key switch 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-
32F and LDM-E32F. 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 "SW3 - Function DIP Switch" on page
13). Lamp/LEDs may function in ‘alarm only’ mode or ‘alarm/trouble’ mode
as selected by switch SW4. Use the charts and examples shown in Appendices
for additional information.
J9 - 24 VDC Lamp Power/System Trouble
Connector J9 is located only on the LDM-32F. 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
Not used on the Sensiscan 2000, MS-9200 and MS-9600.
