Model FS-DLC

Device Loop Card

INTRODUCTION

The Siemens Device Loop Card (FS-DLC) is the driver for the Siemens P2 Addressable smoke detectors,

manual stations, monitor devices and control devices used on the FS-250 Fire Alarm System Control

Units. The FS-DLC contains 9 LEDs for diagnosis of problems.

OPERATION

The FS-DLC initializes, operates, and maintains all devices residing on the loop. The FS-DLC

communicates all relevant device and event information, such as alarms and troubles, to the Main System

Board. The sensitivity of any intelligent smoke detector and the logic functions of any intelligent output

devices can be checked and adjusted from the system display and keypad. All information about the

devices on the loop can be displayed on the system display. The FS-DLC allows the system polarity

insensitive devices to be connected without generating errors.

The FS-DLC supports one loop of 252 Siemens P2 intelligent field devices (252 addresses) as well as

device accessories (relay bases, audible bases, and remote lamps) in any combination. (The on-board

microprocessor provides the FS-DLC with the ability to function and initiate alarm conditions even if the

main board microprocessor fails.)

The FS-DLC contains one reset switch, and 9 LEDs as shown in Figure 1. Pushing the RESET switch

(S1) re-initializes the FS-DLC operation.
