General Info

TheNH3Responderdetectorisaspeciallycongured

Ultra for ammonia response operations. It utilizes two

sensor technologies to cover the ranges of interest in

anammoniaresponseoperation.Therstsensoris

aPIDsensor,whichisconguredtodisplayammonia

concentration readings in the range of 0-1000 ppm.

Over 1000 ppm this sensor displays OL and the LEL

sensorisconguredtodisplay%LELreadingsforthe

explosivelevelsdecisionmakingrange.(10%LEL=

15,000 ppm NH3). Note that there is a 4,500 ppm gap

fromwherethePIDsensorleavesoat1000ppmand

wheretheLELsensorstartsdisplayingat3%LEL.

Additionally, the PID sensor has an extremely fast

responsetimeandisusefulforndingsmallammonia

leaks. Think of it as an “electronic sulfur stick” for

locatingdiculttondleaksby“sning”aroundvalve

packing, sight glasses, shaft seals, etc.

OSHA recommends to bump test the sensor before

eachday’susetoconrmitsabilitytorespondtogas

by exposing the detector to a gas concentration that

exceeds the alarm setpoints. Manually verify that the

audible and visual alarms are activated. Calibrate the

sensorifthereadingisnotwithin20%accuracy.

Important

Upon startup of the unit (every time it is

powered up) it performs a pump test to

check for proper ow. A message will appear

“Block Inlet,” requiring you to block the inlet

with your nger.

Also, at any time during operation if the air

ow sensor detects a signicant change,

it will initiate a pump test and require you

to block the inlet again. This is normal and

shouldn’t be interpreted as a blocked inlet.

See next section for more details.

Latching alarms

If enabled, during an alarm condition the Latching

Alarms option causes the low and high gas alarms

(audible, visual, and vibrator) to persist until the alarm

is acknowledged and the gas concentration is below

the low alarm setpoint. The LCD displays the peak

concentration until the alarm no longer exists. Local

regulations in your region may require the Latching

Alarms option be enabled.

The detector is shipped with the Latching Alarms

option disabled.

Start a bump Test

Perform a bump test regularly to test sensors and

alarms.

To bump test, expose the sensors to a gas

concentration that exceeds alarm setpoints and

that exceeds the alarm setpoints.

Set up IntelliFlash

The IntelliFlash® feature causes the detector, if it is in

compliance (for example, bump tested and calibrated),

toashagreenlighteverysecond(thefactorysetting

default) from the top visual alarm indicator. In Fleet

Manager II, use the IntelliFlash Interval option to

changehowoftenthedetectorashes.

Set up reverse IntelliFlash

IntelliFlashashesagreenlightwhenthedetectoris

incompliance,butReverseIntelliFlash®ashesan

amber light when the detector is not in compliance (a

bump test or calibration is overdue, or a sensor is not

working and has been overridden).

Use Fleet Manager II to change how often the detector

ashesforReverseIntelliFlash.

IntelliFlashandReverseIntelliFlashcanbecongured

in one of four scenarios:

Scenario 1

When both IntelliFlash and Reverse IntelliFlash are

enabled,thedetector’sgreenLEDwillashuntilit

goesoutofcompliance,thenitsamberLEDwillash

instead.

Scenario 2

If IntelliFlash is enabled and Reverse IntelliFlash is

disabled,thedetector’sgreenLEDashesuntilitgoes

outofcompliance,thenitstopsashing.

NH3 RESPONDER

Scenario 3

If IntelliFlash is disabled and Reverse IntelliFlash is

enabled,neitherLEDwillashwhilethedetectorisin

compliance.TheamberLEDwillashifitgoesoutof

compliance.

Scenario 4

When both IntelliFlash and Reverse IntelliFlash

aredisabled,neitherLEDwillashunderany

circumstances.

Set up the condence and compliance

beep interval

TheCondenceComplianceBeepisasoundthattells

the user the detector is in compliance (for example,

bump tested and calibrated). In Fleet Manager II

use the Condence/Compliance Beep option to

changehowoftenthedetectorbeepsforCondence

Compliance Beep.

Connect with IntelliDoX

If a detector’s calibration is overdue and the forced

calibration feature is enabled, the calibration can

be performed with an IntelliDoX docking station or

through the calibration option from the detector’s

main menu.

Connect with an IR Link

The detector can be paired with an IR link, aka dongle.

There is an IR connection at the bottom of the

detectorthatallowsFleetManagerIIcongurationsto

beecientlytransferredtomultipledetectors.The

IRlinkwillalsoallownewrmwaretobetransferred

to detectors or data/event logs to be transferred to

FleetManager II.

Note: You should have the IR Connectivity Kit (sold

separately) to transfer the data from a computer to

the detector.

Bluetooth pairing

The user can pair the NH3 Responder to a mobile

device via built in Bluetooth Low Energy (BLE). The

Honeywell Safety Communicator app, installed on the

mobile phone, can then show gas readings and alarms

from the NH3 Responder that is connected.

Readings and alarms can then be sent to Honeywell’s

remote monitoring software.

1. On the mobile device, turn on the Bluetooth

connection and look for available detectors. On the

NH3 Responder, the Bluetooth connection is on by

default.

2. On the mobile device, select the detector and then

enter the last six digits from the detector’s serial

number.

Note: Pairing is not allowed at start up, during

calibration, or bump test.

Warning: Wireless communication and infrastructure

should be used as informational monitoring only.
