The Simplex 2100 Multiplex system is a sophisticated fire alarm and control system designed for comprehensive monitoring and management of various points within a facility. This manual provides detailed information on jumper placement and switch settings, crucial for both initial installation verification and subsequent modification of the system's operational parameters. The system utilizes transponders, central control consoles, and various peripheral devices like printers and CRTs to achieve its functionality.
Function Description
The Simplex 2100 Multiplex system serves as a centralized control and monitoring platform for fire alarm and other building management functions. It employs transponders to collect data from monitor points (e.g., smoke detectors, pull stations, security devices) and to activate control points (e.g., emergency generators, fire signals, HVAC systems). The central control console acts as the primary interface for system operators, displaying status information, logging events, and allowing for manual control actions. The system's multiplexing capability allows for efficient communication over a single channel, reducing wiring complexity.
Key Components and Their Functions:
- Transponders: These are distributed units that interface directly with sensing devices (monitor points) and controlled devices (control points). Each transponder has a unique channel and transponder number, and can contain multiple encoders.
- Encoders: Within each transponder, encoders are responsible for processing signals from groups of monitor and control points. Each encoder has a unique address.
- Monitor Points: These are input points connected to sensors that detect various conditions (e.g., fire, smoke, security breaches, equipment status). They can operate in three modes:
- NORMAL: For latching alarm devices (e.g., pull stations, smoke detectors). The transponder resets when the sensing device resets.
- LATCH: For momentary alarm indications (e.g., door switches). The transponder latches in the alarm state until reset by the Central Control Console.
- KEY: For both momentary and latching devices. The transponder latches in the alarm state until a keyswitch for that monitor point is momentarily activated, ensuring authorized personnel reset.
- Control Points: These are output points that activate various building systems or devices in response to system events or operator commands (e.g., activating fire signals, shutting down HVAC, starting emergency generators).
- Central Control Console: The main user interface, comprising a CPU, CRT (Cathode Ray Tube) for display, and a printer for logging events. It manages communication with transponders, processes alarms, and provides system status.
- Annunciators: Peripheral devices that provide visual and/or audible indications of system status or alarms, often located in strategic areas of a building.
Important Technical Specifications
The system's technical specifications are primarily determined by jumper and switch settings, which configure communication baud rates, point statuses, and device addresses.
Transponder Configuration:
- Channel Number: Identifies the communication channel for the transponder (e.g., 1-8).
- Transponder Number: A unique identifier for each transponder.
- Encoder Numbers and Addresses: Each encoder within a transponder has a number (e.g., 1-128) and a 4-bit binary address (00-15). The address is set by jumpers connecting to 12VDC (HIGH) or GND (LOW) for bits 1, 2, 4, and 8.
- Monitor Point Status: Configured as Normally Open (NO) or Normally Closed (NC) via jumpers on the zone interface board.
- Control Point Contacts: Configured as Normally Open (NO) or Normally Closed (NC) via jumpers on the zone interface board, determining whether the control circuit is opened or closed when the relay is energized/de-energized.
- Transponder Baud Rate: Selectable via jumpers on the motherboard (37.5, 75, 150, or 300 baud). All transponders on a channel must operate at the same baud rate.
Central Control Console Configuration:
- Channel & Annunciator Baud Rate: Configured via jumpers on the console motherboard. These can be set independently for each communication board.
- 256 Console: Baud rates include 37.5, 75, 150, 300. Jumper locations are specified in a table (e.g., 1-8 for 37.5 baud annunciator, 2-8 for 37.5 baud channel).
- 512 Console: Baud rates include 37.5, 75, 150, 300. Jumper locations are specified in a table (e.g., 1-7 for 37.5 baud annunciator, 3-7 for 37.5 baud channel).
- Printer & CRT Baud Rate: Configured via jumpers on the console motherboard. The CRT uses the same baud rate as the printer.
- 256 Console: Baud rates include 110, 150, 300, 1200, 4800. Jumper locations are specified in a table (e.g., 2-6 for 110 baud, 2-3 for 4800 baud). Earlier 256 versions used 1200 baud, while more recent 512 versions use 4800 baud.
- 512 Console: Baud rates include 110, 150, 300, 1200, 4800. Jumper locations are specified in a table (e.g., 3-7 for 110 baud, 3-4 for 4800 baud).
