Technical Manual: ST-PY-AS - 000026 (Changes are subject to DCRN)
The
ST-PY-AS i
s 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-PY-AS is an attractively-styled, low profile photoelectric
sensor for use with Nittan ‘AS' protocol control panels.
ST-PY-AS features:
• Low profile, stylish appearance
• EEPROM Addressing (Handheld Programmer)
• Low monitoring current
• Supplied with protective dust cover
• Patented
OMNIVIEW
TM
360° LED fire alarm indicator
• Remote indicator output
• Compatible with UB-4 and STB-4SE bases
• Polarised
terminals
• Optical sensor, detecting visible particles of combustion
Section 2 - SENSOR MODELS
The ST-PY-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-PY-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-PY-AS series sensor.
ii)
STB-4SE base
: Similar to UB-4 base, except deeper.
