ALARM WITH LOUD BUZZER and flashing LED light triggered by any contact close.
Alarm with buzzer and flashing LED light features
- Flashing beacon LED is visible in daylight.
- Loud warbling tone cuts through the loudest industrial noise.
- Rugged. Built for rough, wet and corrosive environments.
- Illuminated push button indicates power.
- Compact – box measures only 5 x 5 x 2 inches.
- Relay Output – 15A @ 120 VAC relay.
- Waterproof enclosure is rated for outdoor use. (IP65)
- Snooze alarm – buzzer repeats every 30 mins if deisred.
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.
- A “snooze-alarm” mode repeats the buzzer output every 30 minutes. (can be disabled on the PCB)
- N.O or N.C. relay.
- Manual or automatic reset.
- 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.
- 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″.
Installation
The alarm boxes with buzzer and flashing LED light include a 10 foot cable to connect to your contact close device. If more length is needed, this is an option in the ordering section at the bottom of this page. (So if 10 feet is ordered, this will be in addition to the 10 feet that is included, for a total of 20 feet of cable)
The alarm boxes are configured out of the box to alarm on contact open. This can be changed by setting the DIP switches according to the instructions below.
Models Available
AB-2R has a 10 foot cord with a piggyback plug on the end.
AB-3R models do not use a piggyback cord but instead use two separate cords – a power input cord and a n 8″ drop cord. (or pigtail cord)
A miniature stack light can be
added to either model for more visible status. This feature is designated with the suffix –S2. (so AB-3R-S2 with stack light would be for example) go to AB-3R-S2 page

All our alarm boxes enclosures are rated for outdoor use. For the AC powered units, the cord is an outdoor-rated SJOOW rubber cord but the plug is a standard NEMA 5-15 plug. (not waterproof) If the alarm box is intended to be installed in a wet location then appropriate measures must be taken to make the entire installation waterproof. This means wiring into a waterproof junction box.
The enclosure ingress rating of IP65 can be increased to IP66 by adding a sealing boot over the front pushbutton. More information on Ingress protection ratings here.
Here are the models available:
AB-2R has a 120VAC input and output using a piggyback plug.
AB-3R is for different voltages as in below table:
POSSIBLE AB-3R MODEL NUMBERS:
SAME INPUT AND OUTPUT VOLTAGE DRY CONTACT OUTPUT
AB-3R-12DC AB-3R-12DC-0
AB-3R-24DC AB-3R-24DC-0
AB-3R-24AC AB-3R-24AC-0
AB-3R-120AC † AB-3R-120AC-0
AB-3R-240AC † AB-3R-240AC-0
† These have two cords in addition to the contact close cable. Otherwise the output and input are combined in a single cable, in addition to the contact close cable.
