indicating alarm annunciator (series an2)

series an2 indicating alarm annunciator

up to 8 inputs, integral power supply

the series an2 indicating alarm annunciator provides visible and audible alarms for up to eight inputs. The annunciator also has two spdt relay outputs that can be used to initiate external alarms, buzzers, or paging devices. The integral 24 vdc power supply can power most level, temperature, pressure, and flow switches. Audible alarm conditions can be acknowledged, reset, or silenced either via the front panel push buttons or the rear terminal block. The series an2 can be set to any common isa sequences including first-out.
