Four Input, 1/8 DIN annunciator is ideal for any application where pressure, temperature, level or flow switches require visible and audible alarms. Two annunciators can be easily wired together to form an eight input system. Field selectable logic for ISA Sequence A (momentary or maintained alarms) or ISA Sequence F2A (momentary or maintained with first out). LED alarm and power indication on a NEMA 4 from panel. 1.64" H x 3.59" W x 4.13" D (42 x 91 x 105 mm).
