3.11.4 Two-Wire Smoke Detector Connection
Figure 3-8 shows how to connect two-wire smoke detectors to Class B (Style B) zones.
Figure 3-8 Two-Wire Smoke Detector Wiring
See Appendix A for a list of two-wire smoke detectors that may be used with the SK-5208.
Note: Two-wire detectors can be configured for Enhanced Mode. Enhanced mode is smoke verification for zones
with 2-wire detectors and contact type devices, such as pull stations, used on the same circuit. If the alarm
current is greater than 78 mA, the smoke verification cycle will not occur. See Section 4.2.1 Verify Options
under the Zone Options Menu to program initiation circuits for enhanced mode.
3.12 Supervised Notification Appliance Outputs
Note: To reduce the possibility of false alarms and transient damage, DO NOT bundle telephone wires together
with notification circuit wires.
The SK-5208 provides four Class B (Style Y) supervised notification circuit outputs to annunciate alarm
conditions. For proper operation, you must use polarized sounding devices with a 4.7k ohm end-of-line resistor
