Power Requirements
Processor
- High performance microcontroller with integral digital signal processor (DSP) and Analogue-to-digital (A to D) converter
Sensor Cable and Connections
- Sabre II is designed for use with SabreFonic and SabreLine sensor cable
Method of Detection
- Laser diode transmitter with speckle pattern detection using photo diode receiver
Alarm Relay Output
- One single pole relay contact with changeover contacts rated for 1A @ 12V DC
Ancillary Outputs (Open Collector)
- Two open collector outputs with a maximum rating of 100mA @ 24V DC
Installation, Test and Diagnostic Aids
The Sabre II PCB incorporates a simple user interface comprising toggle switch, push button and 3 seven segment displays and allows all necessary settings to be easily configured without the need for specialist test equipment. A number of operation and diagnostic LED indicators are also included to facilitate test and commissioning. An audio monitor output is also available which may be used as an additional commissioning aid.
Connections
- Electrical connections to the PCB are made via quick disconnect screw terminals. Serial communications cabling is via PCB mounted RJ 45 connectors
Status / Digital Inputs
- 3 tamper protected status inputs are available which may be derived from switches or relay contacts, open collectors or CMOS / TTL level digital signals. The digital signal inputs provide the means by which external equipment may control the unit’s auto-threshold values.
Environmental Specification
- Operating Temperature Range: -10°C to +50°C
- Storage Temperature Range: -40°C to +80°C
- Relative Humidity: Up to 95% (non-condensing) at +40°C
Electromagnetic Compatibility
- The Sabre II meets the requirements of EN55022: 1998, EN50082-1: 1998 and Low Voltage Directive 93/68/EEC
