# Smoke Detectors Wiring
1\. Connect up to 16 (10, if “clean me” option used) 2-wire smoke detectors across zone 1 terminals 8 (+) and 9 (-) as shown in the Summary of Connections diagram at the back this manual. Observe proper polarity when connecting the detectors.
2\. Connect an EOL resistor across the loop wires at the last detector.
3\. Connect 4-wire smoke detectors (up to 16, depending on detector current draw) to any zone from 2-8 as shown in Figure 7 (on next page). Power Reset: This control does not automatically reset power to 4-wire smoke detector zones, so you must use a relay (e.g., 4204, 4229), or on-board trigger to reset power (also required for fire verification). Do this by programming the designated relay/trigger as zone type 54 (fire zone reset); see On-Board Trigger section for other information.
NOTE: Maximum current on trigger 17 is 100mA.
