Alarm with buzzer and flashing LED light

takes an input from sensing devices such as a float switches, reed switches, or limit switches, and turns it into an audio and visual alarm that can’t be ignored. Powered by 120VAC or any other line voltage. Also includes a relay output to power other devices that can be conveniently plugged into the plug included.

Operation

When the alarm box senses a contact close, (or contact open) there is a slight delay meant for sloshing liquids, then the buzzer sounds and the beacon flashes.  When this happens, the annunciation buzzer can be silenced by pressing the front button. After this, the beacon light continues to flash as a reminder until the alarm condition is corrected. When the alarm condition is cleared, the alarm resets automatically so its ready for the next alarm. There are several alternate behaviors available. One of which isthe “Tank Fill” mode where pressing the button stops the buzzer and the beacon LED. This is useful for tank filling operations when the alarm box is simply letting you know that the tank is full, and it is expected to stay full for while.

• A “snooze-alarm” mode repeats the buzzer output every 30 minutes. (can be disabled if needed on the PCB)

• Pushbutton tests the circuit when unit is not actively alarming.

Features

• Waterproof enclosure is rated IP65. (NEMA 4X)
• Installation is as simple as connecting to your device’s contact close (or open) to the communications cable, and then plug in the power cord.
• Different behaviors available on the circuit board such as tank filling (the silence button disables the alarm until next fill-up, snooze alarm or not, N.O. or N.C. relay.
• 15A relay switches a load using either our piggyback plug, or else a standard drop cord. (with model AB-3R)
• Either model is field settable to N.O or N.C. 
• Compact enclosure is 5x5x2″. 

 Models Available

AB-2R has a 10 foot cord with a piggyback plug on the end. This piggyback plug makes it easy to plug your device in.

AB-3R models do not use a piggyback cord but instead use two separate cords. This allows it to accommodate different outputs including a dry contact output.  A contact close uses a communications cable. 

A miniature stack light can be added to either model for more visible status. This feature is designated with the suffix –S3. (so AB-3R-S3 with stack light would be for example)
