Operation - Honeywell Viewguard DUAL AM BUS-2/BUS-1 Mounting And Connection Instructions

10. 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. A cross 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.
Principle of the BUS wiring:

Note: BUS terminal technology requires no end of line resistor.
11. Start-up
11.1 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.
11.2 Apply operating voltage
After applying the operating voltage, the detector automatically
performs an initialisation. Both LEDs flash (see 12.1.4). Do not enter the
Anti-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.
11.3 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.
Especially when mounting higher than 2.5 m, it could be necessary to
increase the range and the sensitivity of the detector or change the
mounting angle.
Important: safety from false alarms is only impaired insignificantly by
this.
11.4 Insert seal
(see Fig. 2-
Ensure that the housing is closed correctly.
Insert the seal. The housing is now locked and can only be opened by
removing the seal.

12.1.3 Operating state "armed" and "disarmed"
The LED indication is blanked
12.1.4 Special case
The red and yellow LEDs flash
- After applying the operating voltage.
- As soon as the BUS communication is correct, the red
LED is switched off.
- As soon as the initialisation is finished, the yellow LED is
switched off (after aprox. 30 sec.).
- If data traffic at the BUS is incorrect.
12.2 Saved covered state
If the covered state is saved, the system cannot be armed.
Clear saved covered state:
1. Remove the cause
2. Activate walk test
3. Trigger detector, the saved covered state is then cleared
The detector is ready to operate again
