NOTE 1:
24V Power Inputs accept a non-polarized 24VDC or 24VAC 50-60Hz (UG-7-A6O-24V version).
Connect power source to appropriate terminals of each detector. Power supply must not be connected to GND
(terminal 1).
NOTE 2:
120VAC Power Inputs accept 110-120VAC 50-60Hz (UG-7-A6O-120V). Connect power source to
appropriate terminals of each detector. See specifications for additional power supply information.
NOTE 3:
Auxiliary contacts shown in standby position. Contacts switch during alarm as indicated by arrows.
Auxiliary contacts are not to be used for connection to the control panel. See specifications for contact ratings.
