Monitoring functions

7.1 Anti-Mask function
The detector identifies when the foil is covered at a distance of up to approx. 30 cm. It
also identifies if the IR foil of the detector has been taped or sprayed.
Operating with BUS-1 and BUS-2/SCM 3000 mode the Anti-Mask function is active only in
the "disarmed" state.
Operating with BUS-2/Viewguard mode the Anti-Mask function is programmable: Active
only in the "disarmed" state / always active / always inactive.
Reaction time : approx. 20 sec., approx. 5 sec. in walk test mode.
The reference value is updated internally so that changes due to contamination, etc. can be
compensated for and the optimum response threshold is maintained.
7.2 Self test
(only AM detector)
In a "disarmed" state, the correct PIR-functioning of the detector is monitored in cycles.
If a malfunction is detected, a corresponding message is transmitted to the control panel.
7.3 Monitoring of operating voltage
The detector is monitored to ensure that the specified minimum value is observed.
If the minimum value is not reached, a corresponding message is transmitted to the control
panel.
8. Programming
8.1 VdS notes
For installation in accordance with VdS standards, the following points must be observed:
Sensitiviy/range:
"High" at 15 m (area), 50 m (long-range) and 30 m (curtain) not as per VdS
Anit-Mask: (only AM detectors)
The Anti-Mask function must be programmed at save. If the covered state is
saved, this prevents arming.
8.2 Function of AM momory
Do not save:
Fault/cover signal is automatically cleared after elimination of the fault/ cover.
Save:
Fault/cover signal remains saved in the detector until it is cleared (see 11.2).

8.4 BUS user address
The DIP switch S2 is for setting the BUS user address. The address setting depends whether
the detector is operated on BUS-2 or BUS-1.
8.5 Settings when operating on BUS-1
- Set S1/1 in "OFF" position.

8.6 Settings when operating on BUS-2
- Set S1/1 in "ON"
The following parameters can be programmed from the control panel via the BUS-2
system:
- Range
- Sensitivity
- Fault/AM
The following functions are supported
- Anti-Mask
- Tamper/backtamper
- Temp. alarm
9. Installation
The feed line is a shielded cable twisted in pairs. Refer to the installation instructions (Chapter
"Lines") for the required cross sections of the corresponding control panel.
The connection terminal operates according to the lift principle and has protection against
misplacing for the connecting wires.Across section of up to 2.5 mm² can be fixed.
The leads must be stripped to a length of 7 mm ±1 mm. If several cores are required per
terminal, ensure that their diameter is of the same size to ensure secure clamping (if
necessary, twisted).
The shield connections must be as short as possible to avoid the risk of an unintentional short
circuit.

10. Start-up
10.1 Check installation
To ensure reliable functioning, all system parts must be installed correctly. Measure all the lines
to detect possible interruptions or short circuits.
Ensure that there is no ground fault.
10.2 Apply operating voltage
After applying the operating voltage, the detector automatically performs an initialisation. Both
LEDs flash. Do not enter theAnti-Mask range during initialisation.
After max. 60 seconds the detector is ready for operation.
After this period, do not change anything in the close vicinity (up to 50 cm) that may influence
the reflected light.
10.3 Walk test
Perform a walk test for every detector
the control panel).
Note: In the Viewguard mode the walk test can be switched on and off directly via the contol
panel. ("Clear detector group" and "arming" only required in SCM 3000 mode and BUS-1).
Check the surveillance area of the detector.
The PIR detector recognizes movements in response to the temperature difference between a
person and the background of the room. Observe while performing a walk test:
There would be different ranges for the monitored area / detection coverage depending on
environment conditions. The walk test should be done under realistic conditions, at this the
clothes of the person and the room temperature do mostly influence the accurateness of the
detection.
To have some reserve even under extremely unfavourable conditions, the detector should be
set to a higher detection range or a second PIR detector should be installed.
10.4 Insert seal
Ensure that the housing is closed correctly.
Insert the seal. The housing is now locked and can only be opened by removing the seal.
