The ST-H2-AS is elegantly designed, low proﬁle ﬁre

sensor which is aesthetically pleasing, thus enabling it to

blend unobtrusively into modern working environments.

Section 1 - INTRODUCTION

The ST-H2-AS is an attractively-styled, low proﬁle heat sensor for use

with Nittan ‘AS’ protocol control panels.

ST-H2-AS features:

• Low proﬁle, stylish appearance

• EEPROM Addressing (Handheld Programmer)

• Low monitoring current

• Supplied with protective dust cover

• Patented OMNIVIEWTM 360°LED ﬁre alarm indicator

• Remote indicator output

• Compatible with UB-4 and STB-4SE bases

• Polarised terminals

Section 2 - SENSOR MODELS

The ST-H2-AS photoelectric sensor has two terminals for connection

onto the two wire loop. The remaining terminal provides a switched

current sink function which operates when the sensor goes into

alarm condition, suitable for the operation of an auxiliary function

such as a remote indicator. Terminal 3 (RIL) is limited to 2mA.

Section 3 - BASE MODELS

A variety of bases are available for use with the ST-H2-AS sensor. It is

important to use the correct base for each application. The available

base models are:

i) UB-4 base: for standard use with ST-H2-AS series sensor.

ii) STB-4SE base: Similar to UB-4 base, except deeper.

Section 4 - INSTALLATION

In normal use, the ST-H2-AS sensor will be installed at ceiling level.

Pass the ﬁeld wiring through the cable hole in the centre and from

the rear of the base. Offer up and afﬁx the base to the ceiling or

conduit ﬁtting with screws via the base mounting holes. Connect

the ﬁeld wiring to the base terminals, as detailed on page 8 making

sure the wiring does not obstruct ﬁtting of the sensor head. Fit the

sensor head by inserting it into the base and turning clockwise until

the notch in the sensor’s rim aligns with base locking screw. The

OMNIVIEWTM 360°LED alarm indicator permits visibility from any

angle.

Note: The address must be set before the sensor is ﬁtted into place.

Fit the plastic dust cover supplied over the sensor to keep out

dust etc, until the system is commissioned. If the dust cover is not

ﬁtted and the environment is slightly dusty, such as when building

work is being completed, for example, problems of false alarms are

likely to occur after commissioning unless cleaning of the sensor is

undertaken. At commissioning, the dust cover should be removed and

discarded.

NOTE: THE PLASTIC DUST COVER MUST BE REMOVED FROM THE SENSOR

IN ORDER FOR THE SENSOR TO FUNCTION CORRECTLY.

Section 5 - MAINTENANCE AND

CLEANING

Maintenance

The ST-H2-AS sensor is a high quality product engineered for

reliability. If proper preventative maintenance is not carried out, there

is a likelihood of malfunction, including false alarms.

Servicing:

Servicing of the system should be carried out in accordance with the

requirements of BS5839 Part 1, Fire Detection and Alarm Systems

for Buildings: Code of Practice for System Design, Installation and

Servicing.

• sensortec • ST-H2-AS • analogue addressable heat sensor instruction manual

The maintenance procedures described below should be conducted

with the following frequency:

One month after installation: Routine Inspection and every 3

months after.

Every 6 months: Operational Test.

Every 12 months: Functional Test and Cleaning.

All above frequencies of maintenance are dependent on ambient

conditions.

Routine Inspection

i) Ensure the sensor head is secure and undamaged.

ii) Check the heat entry apertures are in no way obstructed.

iii)Ensure that the surface of the sensor’s outer cover is clean. If

there are deposits due to the presence of oil vapour, dust etc,

then the sensor should be cleaned in accordance with the cleaning

instructions detailed later in this manual. It may be advisable to

ensure that such cleaning is conducted regularly in future.

iv)Ensure that no equipment which may generate excessive heat has

been installed in the vicinity of the sensor since the last routine

inspection. If such equipment has been installed, then you should

notify the Fire Safety Ofﬁcer or other competent authority that its

presence may cause false alarms.

v) Ensure no equipment which may generate combustion products

or ﬁne airborne particles has been installed in the vicinity of the

sensor since the last routine inspection. If such equipment has been

installed, then you should notify the Fire Safety Ofﬁcer or other

competent authority that its presence may cause false alarms.

Operational Test:

The purpose of the Operational Test is to conﬁrm the sensor’s

correct operation in response to a smoke condition.

Take any necessary precautions at the control panel to limit the sounding

of the alarm sounders/bells and any ﬁre service summoning device.

Test the heat sensor using ‘Detector Testers – Solo’ heat sensor tester,

alternatively, ‘Detector Testers – Testiﬁre’ equipment maybe used.

Check that the sensor gives an alarm condition within 15 seconds.

Check the LED indicator on the ST-H2-AS sensor illuminates and any

remote indicator ﬁtted also illuminates.

Note: Hot air blowers sold for stripping paint etc. generate sufﬁcient

heat to damage the detector and should not be used.

After the sensor has given the alarm condition, reset the sensor

from the control panel. It may be necessary to allow a short time to

elapse before resetting the sensor, to allow any residual heat from

the test to disperse.

iv) Before proceeding to the next sensor, ensure that the sensor just

tested does not re-operate due to the presence of residual heat.

Functional Tests:

The functional test checks the sensors operation. These detectors

may be returned to our factory for Functional Testing.

Cleaning

Note: The sensor head should NOT be disassembled.

i) Carefully remove the sensor from its base.

ii) Use a soft, lint-free cloth, moistened with alcohol, for sticky

deposits, to clean the plastic cover.

iii) Using a soft bristle brush (e.g. an artists paintbrush) carefully brush

between the vanes of the case in a linear motion away from the

apertures on the plastic case.

iv) Ensure that no debris is left on or around the case once cleaning is

complete.
