The LINE-POWERED ALARM BOX takes a contact close and annunciates with loud buzzer and flashing LED.

MULTIPURPOSE ALARM BOX AB-2R
Alarm Box 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 present.
  • 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.

THE ALARM PANEL BOX ANNUNCIATOR takes a contact closure 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.

Operation
  • When your device provides a contact close, the beacon flashes and the warbling buzzer sounds. The button silences the piezo-buzzer while the beacon light continues to flash as a reminder until the alarm condition is corrected. When the alarm condition is cleared, it resets automatically for the next alarm.
  • A “snooze-alarm” mode repeats the buzzer output every 30 minutes. (can be disabled if needed on the PCB)
  • Illuminated push-button to show that that power is on.
  • Pushbutton tests the circuit when unit is not actively alarming.
  • 15A relay switches a load using the piggyback plug, or with model AB-3R, using a separate short cord. (or pigtail receptacle) Either model is field settable to N.O or N.C.
 
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.
 
 Models Available

AB-2R has a 10 foot cord with piggyback plug with NEMA 5-15 plugs. (the standard 120VAC household plug pattern)  The optional mini-stack light model would be AB-2R-S2.

AB-3R models do not use a piggyback cord so they can accommodate different voltages and outputs including a dry contact output. 

The AB-3R voltage input and relay output are contained in a common cable. A rubber-covered SJOOW cord for 110V and higher, or a PVC jacketed communications cable for voltages lower than this.  The contact close is in a separate communications cable. 

For AB-3R units operating from 120V, and when a piggyback plug is not wanted, there is an option for a  6 inch female receptacle dangling from the box, known as a “pigtail plug”” to plug in 120V devices.

  • Power cord…………………………………3C/14, SJOOW jacket (10 ft. piggyback style plug)
  • Communications cable……………………8C/24, PVC jacket 0.032″

PHYSICAL PROPERTIES

  • Buzzer volume……………………………… 103dB @ 2ft.
  • Operating temp (ambient)………………… -40 to 60ºC (-76-140ºF)
  • Ingress protection……………………………IP65 (NEMA 4X)
  • Current consumption during alarm…………30mA
  • Maximum Relay current load……………… 15A @ 120VAC
  • Passive current consumption……………… 5mA (mostly the front button LED)

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.

AB-2R has a 120VAC input and output using a piggyback plug. 

AB-3R is for different voltages as in below table:
