FDT181 Heat Detector
Product Manual
Overview
The heat detector FDT181 is an intelligent detector. It is used for early fire detection
inside a building.
Characteristics
– With built-in CPU, signals received are processed by intelligent algorithm
– Two operation modes: A2S/A2R
– Automatically address setting without encoder setting or DIP switch
– All-around visible alarm indicator
– Resistant to environment and interference factors such as humidity, corrosive and
vibration, with immunity against electro-magnetic interference.
– Communication via FD18-BUS, polarity free connection
– “Sticker Method” easy for commissioning
Functions
– The detection behavior of the detectors is influenced by the operation mode, so that
it can be specifically adjusted according to the environment to be monitored
– Unique ID of each detector, controller can identify the detector type according to the
ID and assign address

Application
– Suitable for use in places where the ambient temperature can change rapidly or
smoke detector are not suitable
– Dust cap protects the detector from being contaminated by construction work
Indicator
The detector is provided with an internal alarm indicator to show its operating status.

Installation
Easy and time-saving mounting
Install the base and finish the wiring during the construction phase.
1. Point the retaining nest to the positioning pointer and insert it into the base.
2. Turn it clock wisely until it stops.
Uninstallation:
1. Turn it counterclockwisely until it stops.
2. Pull the detector out.
After all the construction is finished, the dust cap must be taken away!

Maintenance
Performance test
Recommendation:
– Submit all detectors to an annual visual check. Detectors that are strongly soiled or
mechanically damaged must be replaced.
– Any detectors should be replaced after 7 to 10 years of service, independent from
the environmental conditions.
– Long term auxiliary detectors should be stored with plastic bag.
– Carry out heat test each year.
