Appendix A: Sensiscan 200

Capabilities

When installed with a Sensiscan 200, the modules can annunciate the status

of initiating and notification circuits, relays, and several system control

functions. Up to 32 devices can be connected to the EIA-485

communications output, all addresses combined. Two way communications

can occur with only one annunciator set to address “1”; other devices must

be configured as “Receive Only”. Check battery calculation tables for power

limitations. Each annunciator LED is automatically assigned to one and only

one system point:

Circuits:

• IZ-4F, IZ-4AF, IZ-8F Initiating Device Circuits (alarm and trouble)

• IC-4F, ICE-4F, ICR-4LF Notification Appliance Circuits (activation

and trouble)

• CR-4F, CRE-4F, CR-4LF Control relays (activation and trouble)

• TC-2F, TC-4F circuits (activation and trouble)

System Controls:

• Acknowledge

• Signal Silence

•System Reset

• Activate Notification Circuits 1 and 2, the Remote Signaling Municipal

Tie circuit, and the Alarm Relay.

Connecting EIA-485 Circuit

Communication between the CPU and the annunciator module is

accomplished over a two-wire EIA-485 serial interface.

• Power-limited and supervised.

• 6000 feet maximum distance (with 16 AWG wire) between the control

panel and the furthest annunciator.

• Use twisted pair cable with a characteristic impedance of

approximately 120 ohms.

• EIA-485 circuit rated 5.5 VDC max., 60 mA max.
