Installation and Connection
1. Turn (1) the detector head counterclockwise to the short line and pull (2) it up to disassemble from the
base.
2. Mount the base part by using the mounting place shown (2).
3. Make the cable connections according to the following diagram. Make the connection by observing that
the polarity of Leg No. 4 is (+) and Leg No. 1 is (–), and then by connecting (-) pole from No 2 and (+)
pole from No. 4 of the current detector to No.1 of the next detector.
4. Use the connections No. 3(+) and 2(-) for the parallel notification light.
5. Install the detector head into its place. Make sure that the line on the head piece is aligned with the long
line on the base.
6. Energize the detector. The LED on the detector will blink blue light once in every 20 seconds in the state
without an alarm in order to indicate that the device is in operation. (This feature may be turned off from
the panel)
7. Make the chasis(earth) connection of the cable continuously over the Leg No. 5 between the loop output
and the last detector.
Test
Observable smoke flow must be provided in order to obtain correct results.
In order to perform a smoke test, ensure that the smoke goes into the smoke detection chamber min. for 1
minute by using a burning material or test spray. The LED lights and indicates the alarm when sufficient
amount of smoke enters into the chamber.
1. Fend of the smoke source when the device goes into the alarm state.
2. Check to see whether the red LED’s light continuously. Reset the detector from the panel.
3. The detector must be sent to the service if it does not produce alarm within 1 minute.
4. The system may be activated after the test is performed.
Warning: The product operates only with Teknim TFP-121x, TFP-122x and TFP-123x Intelligent Addressable
Fire Alarm panels.
