Power
Smoke Detector Power - Resettable power for 4-wire photoelectric and ionization smoke detectors can be
obtained from terminals 19 (negative) and 20 (positive). Up to 200mA of current is available, depending on
the number of optional modules in the system (see Appendix B: Table B-2 ).
Non-resettable Power - Non-resettable power can be drawn from Terminal Block 3. Power obtained from
TB3 must be subtracted from available Smoke Detector Power. Note: If both Smoke Detector and Non
Resettable Power is to be drawn from the control panel, limit combined current to 50 mA.

19 ( - )
Unregulated, Unfiltered Power: Devices such as door holders requiring such DC power, up to 200 mA for
door holders, can be connected to terminal #18(+) and 19(-). See Figure 3B for terminal location.
AC Power - Primary power required for this panel is
120 VAC, 60 Hz, 1.2 amperes. Overcurrent protec-
tion for this circuit must comply with Article 760 of
the National Electrical Code (NEC) and/or local
codes. Use #14 AWG or larger wire with 600 volt.
Connect AC power to panel terminals as illustrated
in Figure 3E.
