TECHNICAL MANUAL

Operational check
The operational check can be effected with or without a digital manometer. In
the following the complete check is described. If during the operational check of
TITANUS
PRO · SENS
®
the values vary from those given in the following the
device or its air flow sensor is damaged.
1. Make sure the device has been operating for at least 30 minutes.
2. Close all air sampling points of the test pipe by means of adhesive tape.
After a short initiation period the depression generated in the device
is to
be approx. 250 up to 310 Pa for a set ventilator voltage of 6.9 V and 460 up
to 530 Pa for 9 V.
3. Free the air sampling point at the test pipe again. After about 120 secs
press the Init-button S2 on the detector module. The LED in operation
flashes and the fault LED must go out
(see INSTRUCTION).
4. Close the air sampling points of the test pipe with adhesive tape. After
several seconds of
“blockage”,
the flash code of the LED on the detector
module must flash.
5. Re-open all air sampling points of the test pipe. After a few seconds the
flash code of the LED must go out.
6. Remove the test pipe. The LED flash code on the detector module must
signal
“fracture”
for several seconds.
7. Re-connect the test pipe to the device. After a few seconds the LED flash
code must go out.
A pipe fracture or blockage is indicated by a flash code via the LED of the
detector module:
- fracture: 3x flashing
- blockage:
2x flashing
The corresponding flash code is repeated every two seconds.
The operational check for TITANUS
PRO·SENS
®
2 must be carried out with
steps 1 – 7 for both pipe systems.
I If no fault on the air sampling smoke detection system occurred during the
operational check, the pipe system must be checked.
Connection check
Check that:
1. the pipe system is firmly connected to the pipe connection of TITANUS
PRO·SENS
®
.
2. all pipe fittings are taped and the pipe system is air tight. For this purpose, first
seal all air sampling points (eg with insulating tape).Then measure the air flow at
the opening for the air return or with a test adapter (see chapter 2.3), which must
be installed to the air sampling pipe directly in front of the device.
