Appendix A: Standalone current draw
The current draw of the TS1066 running from battery power only is provided
below for bare configuration:
• Battery charging is off
• Siren is not active
• The tamper input is sealed (wire link, 0 Ω)
• All eight inputs are sealed (10 kΩ EOL resistors)
• The four on-board relays are not active
• There is no relay card attached
• USB is not connected
• The RS-485 system LAN is terminated and is connected to a terminated
ChallengerPlus panel Comms port.
• The local LANs (BUS 1 and BUS 2) are not terminated and not active (no
connection)
• Ethernet is not active.
Consumption = 226mA (whilst battery voltage is 12.0V)
• Active Ethernet adds 25mA.
• Each active relay coil adds 55mA.
Note: Relay coil current forms part of the allowable user current draw. Refer to
Appendix B: Output fusing and user current limits on page 34.
