Page 14: Installation
Installation Pre-Installation Routines The 4098-9687 Stand Alone Duct Detector should be installed in a location of relatively nonturbulent air flow and within the intended operating velocity range of 300-4000 feet-per-minute (91 to 1220 M/min.). Simplex recommends measurements of air flow and examination of engineering specifications that define expected duct air velocities under all conditions. - Page 15 Installation, Continued Rules to Follow (continued) DETECTOR EXHAUST DAMPER RETURN EXHAUST DO NOT LOCATE DETECTOR HERE RETURN AIR DAMPER FRESH SUPPLY INTAKE DO NOT LOCATE FILTER DETECTOR (O.K.)

Page 19: Accessory Installation
Installation, Continued Accessory Installation The 4098-9842 Duct Control Station is intended for installation to a standard double-gang outlet box having a depth of at least two inches. See Figure 11 for basic mounting details. Make wiring connections in accordance with the wiring diagrams (Figures 2 and 3) prior to attaching accessory to the box. -
Page 20: Detector Replacement
Installation, Continued To properly remove and replace the detector to the base (see Figure 1): Detector Replacement Remove power from the Stand Alone Duct Detector. Loosen the four screws that secure the clear plastic cover to the housing base. Insert a small blade screwdriver into the lock release slot in the base. Rotate the detector counterclockwise to remove it from the base. -
Page 21: Magnetic Test For Photoelectric Detectors
The 4098-9601 photoelectric detector may be tested by placing a magnet at the Photoelectric Detectors location indicated by a “TEST” mark embossed on the cover for four (4) seconds (see Figure 12). Use the Simplex Magnet Tester (Part No. 553-810), Table 3, and the following information to test detectors. TEST MARK... -
