Alarm annunciator displays process status with miniature stack light. Model AB-4
The compact AB-4 annunciator is like our other alarm boxes but also displays the status of an operation – green for OK, red for an alarm condition, accompanied by a loud buzzer. The miniature stack light fits on a box that is only 5×5 inches for a compact package. Setup is easy: just connect the included communications cable to a contact close (or contact open) and then plug it into power.
Alternatively the annunciator can be powered from other voltages. (12VDC, 24VDC, 220VAC are the most common)
There is a relay output available. We provide a convenient piggyback cord to connect a pump, heater or other device.
When there is an alarm condition, the buzzer sounds, and the red stack light flashes. Push the front button to silence the buzzer but the red LED continues to flash until the condition is corrected. The built-in snooze alarm will sound again in 30 minutes. This can be bypassed by setting a jumper on the circuit board if desired.
The PVC enclosure measures only 5×5 inches.
It has an IP65 ingress rating. (suitable for wash-down duty)
All parts are designed to take corrosive environments.
