New value indicator AS2000-3



AS 2000-3, the practical annunciator for 4 alarm circuits with normally open contacts, incorporates flasher, horn relay, lamp test and, where necessary, a power supply for the 230VAC version, all compactly mounted in a single enclosure. The incoming alarm singals are indicated visually by flashing light and audibly by a horn. All controls and annunciating elements are mounted externally.


When an alarm contact opens, a relay integrated in the AS 2000-3 energizes, whereupon the flasher starts, and the horn relay switches into self-holding operation. The assigned alarm lamp begins to flash and the horn sounds. Pressing the acknowledgement button (AQ) shuts off the horn and switches the alarm lamp from a flashing to a steady light. The lamp will extinguish once the fault has been removed. In the 230V version, the alarm contacts are supplied with low-voltage from the system. These conditionally potential-free contacts mean low-voltage cables can be used for the connections. Pulse-type alarms are stored (horn and flashing light), and return to their idle state afteracknowledgment. The flash frequency of the alarm lamps can be adjusted to 0.5, 2 or 8Hz through replugging them on the PCB. The factory setting is 2Hz
