Description
The Combination Photoelectric Smoke/Heat Detector (FDKLU026-D-X) is an Analog/Addressable smoke detector and fixed temperature heat ofInteglex Multicrest series. The detector and base (not included) are made of a durable plastic in an eggshell white (off white) to blend in with theceiling.
The new Nohmi circuit integration technology was introduced to the FDKLU026-D-X. This state-of-the-art technology was able to simplify theproduct circuits and down-size the product structure significantly.
The FDKLU026-D-X has an alarm set-point range of 3.4 to 11.6%/m (1.05 to 3.69%/foot) in smoke detection and is UL listed. The FDKLU026-D-X
is also a 57°C (135°F) restorable heat detector. The FDKLU026-D-X can be configured for drift compensation and has built in dirty detector
warning as well as.
The FDKLU026-D-X and the control panel communicate over a proven and robust digital communication path and the system analyzes the levelof alarm at the particular device. The total polling speed is less than five (5) seconds, well under the UL requirements. The FDKLU026-D-X is listed
to both UL 268 Smoke Detection Standard and UL 521 Heat Detection Standard.
The FDKLU026-D-X has two LEDs that allow for 360° viewing. The detector is compatible with any of the Nohmi bases and simply twists on. TheFDKLU026-D-X is addressed using the hand held programmer or the control panel addressing function.

Setting the Address
Each addressable module, smoke detector, heat detector and combination detector must have the address set before connecting the device tothe Signaling Line Circuit (SLC) loop. The address is set using the hand held device programmer or the addressing feature on the control panel.

Compatible Bases

All bases will mount on a single gang, double gang, octagon, 4 inches square or mud ring electrical box.
