ATTENTION!
Before starting to operate IT-12-Exd explosion-proof test transmitter, carefully
read the Operating Manual.
During the testing of detectors it is compulsory to switch off firefighting
equipment.
1. DESCRIPTION
The purpose of IT-12-Exd explosion-proof test transmitter (hereinafter “the
transmitter”) is remote testing of operational performance of Spectron-601-Exd
series flame detectors issued on 01.01.2017 or later.
The transmitter is produced in compliance with requirements to ex-proof
equipment of subgroups IIA, IIB, IIC according to TR CU 012/2011, GOST
30852.0 (IEC 60079-0), GOST 30852.1 (IEC 60079-1) and complies with
1ExdIICT6 explosion-proof marking.
The transmitter is designed to be used in indoors and outdoors explosion-hazard
areas according to the classification in chapter 7.3. of Electrical Installation Code,
GOST 30852.9, GOST 30852.13 and other directives that outline the application
of equipment in explosion-hazard areas. The transmitter features a D16 grade
aluminum body and has IP68 Ingress Protection Degree from environmental
impact. The transmitter’s body is covered with black powder paint.

3. USAGE INFORMATION
3.1. DESIGN AND FUNCTION
The transmitter includes an aluminum body that consists of a reflector, an
electronic board with light-emitting diodes, a mode selection switch and a battery
compartment cover –see Fig. 2. The battery compartment is filled with
compound.
The transmitter has the following operating modes:
•testing the detector’s switching into the Fire mode
•testing the detector’s switching into the Failure mode testing glass
dustiness - in the automatic mode.
ATTENTION!
During the testing of detectors it is compulsory to switch off firefighting
equipment.
Testing of the detector should be performed from the distance of 25 m maximum.
During the testing, the transmitter’s axis should be aligned as much as possible
with the direction to the detector. Get as close to the detector as possible if
neighboring detectors are installed in close proximity to the tested one.
3.2. FIRE MODE
Use the condition of the light-emitting diode indicator to make sure that the tested
detector is in the stand-by mode.
Turn the transmitter on by turning the switch to align the marking on the body
with F1 or F2 or F3 signage (Fig. 2); the light-emitting diodes should be blinking
at this time. Point the transmitter in the direction of the detector’s front-face
surface. Hold the transmitter until the detector goes into the Fire mode. At this
4
time the detector’s indicator shall switch to continuous lighting mode. FIRE relay
is off.
ATTENTION!
Do not hold the operating transmitter for longer than 28 seconds: after this time
the FIRE relay shall activate in the detector.
To turn the transmitter off, turn the switch until it clicks and the marking on the
body is not aligned with F1, F2, F3 or F4 signage; the light-emitting diodes should
go out at this time (the switch is in the OFF position between F modes).
After you turn the transmitter off, the detector will automatically go into the
Stand-by mode.
If glass dustiness has reached a critical level, the detector will go into the Failure
mode during the Fire mode testing, activating FAILURE relay and the
corresponding light-emitting diode indication.
3.3. FAILURE MODE
Use the condition of the light-emitting diode indicator to make sure that the tested
detector is in the stand-by mode.
Turn the transmitter on by turning the switch to align the marking on the body
with F4 signage (Fig. 2); the light-emitting diodes should be blinking at this time.
Point the transmitter in the direction of the detector’s front-face surface. Hold the
transmitter until the detector goes into the Failure mode. At this time the
detector’s indicator shall switch into the frequent blinking mode.
FAILURE relay is off.
ATTENTION!
Do not hold the operating transmitter for longer than 28 seconds: after this time
the FAILURE relay shall activate in the detector.
To turn the transmitter off, turn the switch until it clicks and the marking on the
body is not aligned with F1, F2, F3 or F4 signage; the light-emitting diodes should
go out at this time (the switch is in the OFF position between F modes).
After you turn the transmitter off, the detector will automatically go into the
Stand-by mode.

3.4. BATTERY CHARGING ATTENTION!
Only charge batteries outside of explosion-hazard areas.
To charge batteries:
1. Make sure the transmitter is off (the marking on the body is not aligned with
F1, F2, F3 or F4 signage on the switch, the light-emitting diodes are off). 2.
Make sure the battery’s temperature is from 0°С to +45°С.
3. Unscrew the battery compartment cover, see Fig.2.
4. Connect the charging adaptor (included in the delivery package) for 220V,
50Hz network to the transmitter’s slot. The batteries need at least 2.5 hours
to charge.
5. Disconnect the charging adaptor and screw the battery compartment cover
shut with a 19mm wrench until the sealing ring is compressed.
NOTE
Charge the batteries before using the transmitter.
During long storage, battery capacity is reduced due to standing loss.
4. SAFE OPERATION REQUIREMENTS
Assembly and operation shall be performed in compliance with Operating Manual
requirements, chapter 7.3 of “Electric Installation Code”, GOST 30852.0, GOST
30852.1.

Observance of safety rules is a necessary requirement for safe operation and
functioning of the transmitter.
Operation of the transmitter should be performed by authorized personnel that
received training, an assessment by a certification committee and got acquainted
with the Operating Manual and instructed on safe service and maintenance.
All maintenance work on the transmitter associated with removing the battery
compartment cover must be performed only outside of explosion-hazard areas.
Maintenance personnel shall be responsible for occupational safety.
Explosion safety of the transmitter is provided by:
•type “d” ex-proof shell;
•in compliance with GOST 30852.1 conducting parts and sparking parts are
installed inside an ex-proof body that is resistant to explosion pressure and,
along with protection means, prevents explosion transfer to the explosion-
hazard environment; the battery compartment cover is threaded to the
body.
•in normal operating mode, the heating temperature of the outer surface does
not exceed temperatures recommended for electrical equipment of the
corresponding temperature class, in compliance with GOST 30852.0;
•the body’s threaded joint is covered with TSIATIM-221 GOST 9433
lubricant;
•the body corresponds to the high degree of mechanic stress in compliance
with GOST 30852.0.
5. TROUBLESHOOTING ATTENTION!
The transmitter is not designed to have its components repaired by the user.
If the transmitter is on but its light-emitting diodes are not luminescent you should
charge the batteries according to section 3.2 - Battery Charging.
If light-emitting diodes did not resume luminescence after the batteries have been
charged please contact NPO Spectron Service Desk.
