Photoelectric smoke detector EP 212-41M
Photoelectric smoke detector is used to warn about fire and smoke in enclosed spaces
Duplex wire with voltage from 9 to 27 V supplies the detector with energy; it is possible to change the voltage up to 100 ms with a repetition period of not less than 0.7 s.
- Suitable amperage 95 mA (maximum- 150 mA)
- Operation by inertia no longer than 5 seconds
- Outgoing "alarm" signal sounds in case of sudden drop in internal resistance to the level not less than 500 Om, with voltage of 500 mA, red indicator switches on immediately.
- Response signal is restarted from the control panel when the current supply is cut off for at least 2 seconds.
- Resistance between the detectors "3" and "4" is not more than 2 Om
The detector remains operational under the following conditions:
- Air flow rate is up to 10 m/s
- Background lighting is up to 12000 lx (from an artificial or natural light source)
- Temperature ranging from -25 till +55oC
- Air humidity (93 ± 3) % at temperature + (40 ± 2) oC.
The size of the detector with an installation base is no more than 106х40 mm
The weight of the detector with an installation base is not more than 210 g
