Remote Control Extension

The remote control extension is suitable for table‑top and 19‑inch rack mounting installation.
Two brackets for rack-mounting are supplied. Installing a remote control extension is similar
to installing a voice alarm controller (see section Voice Alarm Controller, page 43). The
brackets can also be used to attach the remote control extension to a wall.

Remote Control Extension Kit

The remote control extension kit is suitable for table‑top and 19‑inch rack mounting
installation. Two brackets for rack-mounting are supplied. Installing a remote control kit is
similar to installing a voice alarm controller (see section Voice Alarm Controller, page 43).

End Of Line detection board

To install an EOL, use these general notes:
–
–
Notice!
You must use either EOL or impedance measurement, not both.
Notice!
Do not connect the EOL board to the secondary side of a volume control.
The secondary side of a volume control can attenuate the pilot tone.
All inputs to a VAC or router that have an EOL input must be normally closed inputs. The EOL
board operates with a normally closed output and the configuration software is set to Action
Open. Use another router to receive normally open inputs.
Notice!
During a call the pilot tone is absent in zones without a call or without background music. The
LED on the EOL board is dim. The EOL input is ignored during calls to avoid false fault
readings.
The short circuit check must be set in the configuration software.
Notice!
The EOL board detects a short circuit, but the EOL cannot detect where the short circuit is.
Notice!
It is possible for the LED to turn off before the contact is opened or vice versa. This level
difference is typically less than 500 mV.
Bosch Security Systems B.V.
An EOL board can only be installed in a 2‑channel system. The EOL board needs the
second amplifier to produce the pilot tone for the zones that are not in use. Refer to
section 2-Channel mode operation, page 78.
The volume control on the VAC must be set to -9 dB or higher. The recommended setting
is 0 dB. A lower dB setting attenuates the pilot‑tone.
