Optical sensor (smoke sensor) The optical sensor uses the scattered-light method. An LED transmits light to the measuring chamber, where it is absorbed by the labyrinth structure. In the event of a fire, smoke enters the measuring chamber and the smoke particles scatter the light from the LED. The amount of light hitting the photo diode is converted into a proportional electrical signal. The dual-optical versions use two optical sensors with different wavelengths. The Dual-Ray technology works with an infrared and a blue LED so that lightest smoke is detected fast and reliably
The FLM‑420‑O1I1 Output-input Interface Modules are fitted with one output to control external devices and with one monitored input. They are 2‑wire LSN elements for connection to the fire panels FPA‑5000 and FPA‑1200 and offer the enhanced functionality of LSN improved technology.
The FMC‑210‑DM Manual Call Points are used for manual triggering, and are deployed in the Local SecurityNetwork LSN and LSN improved. Form H Manual Call Points are designed for outdoor deployment, form G Manual Call Points are designed for indoor deployment.
Thermal sensor (temperature sensor) A thermistor in a resistance network is used as a thermal sensor from which an analog-digital converter measures the temperature-dependent voltage at regular intervals. Depending on the specified detector class, the temperature sensor triggers the alarm status when the maximum temperature of 54 °C or 69 °C is exceeded (thermal maximum), or if the temperature rises by a defined amount within a specified time (thermal differential).
The device allows to select 32 types of alarm and evacuation tones (including DIN tone 33404, part 3) for different requirements. You can adjust the sound pressure by five levels according to the operational environment. Depending on the tone type and volume set, the sound pressure varies between 65 dB(A) and 92.1 dB(A). Sounders of the same LSN loop and with the same tone type provide immediate synchronization. The device maintains LSN loop functions in the event of wire interruption or short-circuit thanks to two integrated isolators. Change of the device settings can be done in the FSP-5000-RPS programming software.
