Page 5: General Description
The Analog smoke detector with isolator has low profile housing. The latest IC technology will secure the highest reliability possible. The 4401I smoke detector is not backwards compatible with older detector types. Only Advanced mode is supported. The unit is intended for indoor use and in dry premises. -
Page 6: Address Setting Check
3.1.1. ADDRESS SETTING CHECK The red LEDs will be blinking every 3 seconds when the detector is powered and the COM Loop address is not set, that is as long as the address is “000”. 3.2. IR LED The smoke detection chamber consists of an IR LED and a photodiode. Reflection of the infrared light is used to detect smoke. The smoke enters the detection chamber through an insect filter and an optical labyrinth. -
Page 7: Short Circuit Isolator
3.3. SHORT CIRCUIT ISOLATOR The 4401I smoke detector has a built-in short circuit isolator that requires no separate COM loop address. Like any other short circuit isolator, it will be given an individual sequence number when programmed in EBLWin. The isolators have to be connected consecutively regarding sequence number 00-127, in the COM loop's A-direction. -
Page 8: Fire Alarm
This will secure real fire alarms and minimize the not wanted nuisance alarms, for example due to artificial smoke or oil mist. 4.1.1. ALARM THRESHOLD LEVELS The 4401I smoke detector has the following fire alarm threshold levels: Area alarm algorithm S [%/m] Normal (default) - Page 9 4401I ANALOG SMOKE DETECTOR WITH ISOLATOR - FIRE ALARM SOLUTIONS TECHNICAL DESCRIPTION Area alarm algorithm Data 1 (%/m) data 1 < 0.2 0.2 ≤ data 1 < 0.3 Normal Clean 0.3 ≤ data 1 < 0.4 0.4 ≤ data 1 < 1.3 1.3 ≤...

Page 10: Learning Function
4.2. LEARNING FUNCTION Depending on the local occurrence of smoke where the detector is situated, each detector can after a learning period adapt a more appropriate alarm algorithm than the default (Normal). A learning period contains of twenty 36h-periods (20 x 36h = 720h = 30 days = one month). When three (or more) of the 36h-periods, during the learning period, have exceeded the area alarm algorithm level, the area alarm algorithm will be adapted. -
Page 11: Sensitivity Compensation
4401I ANALOG SMOKE DETECTOR WITH ISOLATOR - FIRE ALARM SOLUTIONS TECHNICAL DESCRIPTION 4.3. SENSITIVITY COMPENSATION In order to maintain a constant sensitivity regardless of the contamination of the detector, a Contamination Compensation Factor (CCF) is subtracted from the momentary smoke obscuration values before evaluated in the alarm algorithms. -
Page 12: Function
The control unit will set the install date for the detector automatically when it detects a new detector. The new detector 4401I keeps track of its install date to support this function. Therefore, a service signal is given for a 4401I detector older than the following number of years: •... -
Page 13: Set The Com Loop Address
If the address setting tool is used, the COM loop address and mode settings have to be done before the unit is connected to the COM loop. 7. SET THE MODE Since the 4401I smoke detector is not backwards compatible with older detector types, only Advanced mode is supported. -
Page 14: Mounting
The detector is plugged in an analog base, 4412F or sounder base 4479. The 4401I smoke detector will not fit in bases 3312, 3312F, 3312FL, or sounder base 3379. Place the detector in the base with the detector's "Mark" in the same position as the "Mark" on the base and turn the detector clock- wise. -
