Technical Specification

LVDCompliance The unit is designed and manufactured to safety specification BS EN61010-1:1993 Environment

Inputs Outputs

Operating temperature–20°C to +60°C Storage temperature–20°C to +80°C Humidity0–95% RH, non-condensing ProtectionIP41 Alarm Contacts Volt-free contacts which can havethe operating mode configured using the Setup Card, to operate toalarm for contact open or to alarmfor contact closed. Lamp Drive All inputs are opto-isolated (isolation voltage 500VDC). By using different wiring configurations, the same system can be used for both: Each output can drive up to 160mA at 24VDC, making it suitable for multi bulb displays or multiple repeat displays. Standard Relays Communications Standard relays fitted on the Setup Card: Horn, Group and Watchdog. Contact rating 3A at 24VDC resistive or2Aat 240VAC resistive. Selection of N/O or N/C contact by jumper link. Alarm data can be transmitted using the serial communications port to other System 9000 units, DCS systems, PLCs or computers.Transmission – RS485C. Full duplex,1start bit, 7 data bits, 1 parity,1stop bit.Baud Rate – up to 9600 Protocol – ASCII MODBUS and RTU Alarm Contact and Cable Resistance Voltage input from 19VDC minimumto 36VDC maximum with a common 0V for the 24VDC system and 38 to 58VDC for the 48VDC system. 110Vfield contact voltage option N/C contact – series resistance ofcontact cables 20k Repeat and Group Relays Ω maximum. N/O contact – parallel resistance ofcontact cables 200k Group relay card and individual repeat relays for each alarm way. Contact rating 3A at 24VDC resistive or 2A at 240VAC resistive. Relay ouputs may be normally energised or normally de-energised and contacts can be N/O or N/C. Ω minimum. Field Contact Voltage and Current The voltage for volt-free alarm contacts is fed from the unit at 24VDC at approximately 2mA.To maintain complete isolation it ispossible to use a separate PSU to feed allthe alarm contacts. Input Transient Filter (24V input) Signals narrower than approx 40ms at 30V will not trigger the annunciator.Tolerable transient at higher voltages:100V for 2ms 200V for 1ms 1kV for 200µs First-up Discrimination Typical 10ms Control Inputs Any input can be configured to one of the following control inputs: Lamp test Mute Acknowledge First-up reset Reset Sleep System test Horn Inhibit
