Thermalert GP Series Operator’s Manual 33
APPENDIX B RAYTEK INFRARED SENSING HEADS
This section describes how to connect Raytek infrared sensing heads to the
Thermalert GP monitor. Raytek sensing heads include the Thermalert GPR
and GPS (laser) sensor (Head Type H001), the Thermalert GPM (Head Type
H002), the Thermalert CI3 (Head Type H003), and the Thermalert TX, which
uses the 4-20 mA connection (Head Type H005).
B.1 THERMALERT GP SENSOR MODELS
Table B-1 lists available Thermalert GP sensor models. If you need to connect
other Thermalert heads, such as the Thermalert CI3 and TX, use the wiring
layout in Table B-4. For information on selecting head/device types, refer to
Section 2.4.2. For information on CI3 or TX specifications and use, refer to the
manual that came with the sensing head.
