Every detector bottom has a “Chamber Maid
Plug” (cleaning opening with a plug) for blowing out the
optical chamber with compressed air (not required for
the FCH-T320/FCH-T320‑R470 Heat Detectors).
7.1 Coding of the Detector Types
With the exception of the FCP-O320 and FCP-O320-R470, every detector has a colored
detector type identification ring around the central individual display.
This facilitates inspection by service personnel.

7.2 Test Procedure for Detectors with C-Sensor
You must first test the optical unit of the FCP-OC320 with the test aerosol. Reset the detector
when you have released the Osensor. This switches the Csensor into revision mode for
15minutes and it can then be tested. Since the aerosol test for the detectors works like a
disturbance signal, (very large sig-nal with very quick increase), the signal evaluation for
disturbance variables is brought to bear and alarm signaling occurs only after approx. one
minute.
1. Position the Smoke Detector Tester on the FCP‑OC320.
2. Spray aerosol (1 to 2seconds).
Do not remove the test device from the detector; the Osensor triggers only approx.
60seconds after the application of the test aerosol.
3. Reset detector.
This switches the detector to revision mode.
4. Place CO Testing Gas bottle in the test device.
5. Position test device on the detector.
6. Apply CO gas for 1/2 to 1second.
The Csensor triggers after approx. 20seconds.

Notice!
In revision mode the chemical unit of the detector can be tested separately. A minimum CO
gas concentration of 30 to 35ppm is required when the chemical sensor is tested. This is
guaranteed if the test is performed with the CO Test Gas bottle as described.
