Appendix A: Sensiscan 2000

Capabilities

When installed with a Sensiscan 2000, the LDM Series modules can annunciate
general system status; the status of all initiating and notification circuits and
output relays. Plus, manually activate all points via control switches. Each
lamp driver output may be assigned to one and only one system I/O point:

Optional Sensiscan 2000 plug in Modules -

IZ-8F - Initiating Device Circuits (alarm and trouble)
IZ-4F/IZE-AF - Initiating Device Circuits (alarm and trouble)
IC-4F/IC-4CCF - Notification Appliance Circuits (trouble)
ICE-4F - Notification Appliance Circuits (trouble)
CR-4F/CRE-4F - Control Relay Modules
TC-2F/TC-4F - Time Control Modules

Sensiscan 2000 modules are user configurable. Refer to the Sensiscan 2000
Manual.

System Control Switches -

Acknowledge
Signal Silence
System Reset
Activate selected system outputs (notification circuits, relays)

System Control Switches on the Sensiscan 2000 CPU may be remoted via the
LDM series modules. Also, zone/point control switches may be configured.

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 Sensiscan 2000. Loss of communication results in System Trouble and
Module Failure indications at the CPU.

Programming and Testing the LDM-32F

After complete installation, the Lamp Driver Module(s) must be programmed
into the control panel as if it were an annunciator. After programming the fire
alarm control panel to accept them, fully test the LDM(s) by ensuring that each
switch and LED performs its intended function, and that the LDM(s) can
perform the functions outlined in "3. Operation" on page 27.
