Operation manual for JTF-GDM-936E spot-type multisensor
smoke and heat detector
Before installation and use of the product, please read the product operation manual
carefully
I.
General
JTF-GDM-936E spot-type composite smoke-sensing and temperature-sensing fire detector (hereinafter
referred to as the detector) is a multi-element composite detector constituted jointly by a smoke sensor
and a semiconductor temperature sensor in respect of technological structure and circuit structure. It has
not only the performance of photoelectric smoke-sensing fire detectors but also the performance of
temperature-sensing fire detectors.
This detector uses a non-polarity two-wire bus system, and can be jointly used with the 9000 series
alarm controllers produced by our company.

2.
Wiring mode: The detector is connected into a compatible fire alarm controller via a two-wire bus
system through non-polarity connection mode and the L1 and L2 of the two-wire bus system are
connected with the terminals 1 and 3 of the matched base. The schematic diagram for connection of
multiple detectors and a controller is shown in Fig. 3.

3.
Address encoding: As shown in Fig. 4, connect the detector through a detector base on the encoder
with L1 and L2 connected in non-polarity mode; set the encoder to encoding function, compile a correct
address code, and press the “Run” key to complete the address encoding setup.
(Note: For the detailed operations, please refer to the encoder operation manual.)
