3 Introduction System 57 is a fire and or gas control system offering great flexibility through its modular construction. The system is constructed in a rack that can be fitted with fire and/or gas control cards and corresponding interface cards that allow connection of the associated detectors. The rack can be panel or cabinet mounted. Further details of the main components are given below. A graphical overview of all the available components and how they can be assembled into a system is shown in section X. For further detailed information refer to the individual operating manuals 05701-M-5001 (5701 gas control card), 05704-M5001 (5704 gas control card) and 05704-M-5002 (fire control card). 3.1 Gas Control Cards The System 57 gas control cards provide display and alarm facilities for the full range of Sieger gas detectors. Their back lit, multi-part LCD displays the gas reading and status in both analogue bar graph and digital numeric forms. In addition, there is an alpha numeric message section to give detector (and engineering function) status. There is a choice of either the single channel 5701 or the four channel 5704 gas control cards. Each card has two input options; one is for catalytic bridge type while the other is for 4 to 20mA detectors or transmitters. The control cards feature 3 levels of alarm, options of individual, zoned, voted, master, time delayed, update and rate of rise alarm facilities, 4 part LCD display, peak reading facility and detector performance monitoring. 3.2 Fire Control Cards The 5704F fire control cards provide display and alarm facilities for a wide variety of fire detection products and provide up to four fire zone inputs compatible with most flame, smoke and heat detectors and manual call points. The status of each fire zone is individually displayed by high intensity LEDs. In addition, each card has two line monitored alarm output circuits. Both fire and gas control cards can be freely mixed in a rack. Up to 60 fire zones can be monitored per 19" rack. Each rack that contains a 5704F fire card has one 5704FS fire status panel fitted. The 5704FS fire status panel provides common display and alarm indication for all of the fire cards in a rack as well as a local audible sounder. It also provides common push buttons for executing specific fire card related functions. 3.3 Master Alarm Update Panel The master alarm update facility can be enhanced by adding the optional master alarm update panel which enables update facilities without the need for external wiring. The alarm update panel is 1" wide and provides audible and visual alarms and a reset and accept push button. 3.4 Power Supply Units The power supply units are rack mounted to match the main control card rack design. The units are 1U high, and available in 19" & ½ 19" sizes. Total maximum power capability is 200W (built in 50W blocks). The input voltage is auto sensing (AC or DC) and the output is regulated DC with over voltage and overload protection. 3 System 57 Quick Start Guide 05701-M-5026 MAN0839 Issue 1 3.5 Engineering Card The System 57 engineering card provides full maintenance and set up facilities for each channel card. The front panel has a series of tactile feedback push buttons that allows checks of the alarm levels and performance to be carried out for each channel. A real-time ‘on board’ clock provides calibration history and calibration overdue reminder functions. An access key provides security protection. The engineering card can be fitted with optional modules for extended system options. 3.5.1 Serial Communications Module The serial communications module provides a gateway between the System 57 rack and a remote device (DCS, PLC or SCADA package) to allow the continuous monitoring of each channel’s operation and condition as well as allowing remote configuration of the system operation. The module uses the industry standard MODBUS RTU protocol, RS485/422/232 standard. Custom designed SCADA graphics packages are also available. 3.5.2 RS232 Printer Driver Module The printer driver module provides a serial output in the event of a gas alarm, fault or user intervention. The output is RS232 ASCII event data, has selectable print criteria, provides time and date stamping and is electrically isolated. 3.5.3 Master Alarm Update Module The alarm update module provides a common alarm indication with new alarm event update. It also provides 2 Outputs: 1 relay, 1 Darlington, with selectable operation: pulsed or continuous and an alarm and common alarm reset input. It complies with ISA ‘M’, DIN 19 235. It can be used with the optional master alarm update panel. 3.6 Interface Cards There are 9 versions of interface card available (5 for 5701 Gas, 2 for 5704 Gas and 2 for 5704 Fire Control Cards). The interface cards provide the link between the various fire or gas detectors and the control cards. They provide detector interface, offer flexible relay options, and allow an individual control card power option. A high integrity relay operation version is also available. The terminals accept ≤ 2.5mm2 (14AWG) gauge cable. 3.7 Rack Assemblies System 57 racking units provide mounting options for the system 57 control cards and interface cards. The racks are available complete with a DC input card and an engineering card. The racks are 3U high, with front or rear wiring options. Half and full 19" versions are available accommodating up to a maximum of 64 channels of gas detection or 60 channels of fire detection in a single rack, or a combination of both. 3.8 Cabinet Assemblies The System 57 cabinets provide a convenient and compact mounting of the rack assemblies and PSUs. They are wall mounting and available in half and full 19" versions. The cabinets have an IP54/Nema 12 ingress protection rating, pre-formed bottom-entry knock-out gland entries and an accessory mounting plate.
