VACIE control inputs and outputs
The PRA-MPS3 provides control inputs and outputs. The control inputs can be used as voice
alarm inputs from the fire detection equipment, the Control and Indicating Equipment (CIE).

Open interface
Next to control inputs and outputs and control via a call station with extensions, the
PRAESENSA VACIE supports a TCP/IP based Open Interface with connection supervision for
interfacing to external control device(s) such as standardized user interfaces required by
local regulations. This interface only allows for access to level 1 and level 2 functions.
Mandatory functions of the VACIE are not overridden.

The proper functioning of the VACIE in accordance with EN 54‑16 is the joint responsibility of
the manufacturer of the system elements and the installer. The system elements and
documentation for installation and configuration are reviewed, tested and certified for
compliance by a Notified Body. The installer is responsible for the correct design,
installation, interconnection, configuration and maintenance of the system for compliance to
EN 54‑16 and EN 54‑4.

EN 54‑16 / EN 54‑4 compliance checklist
Make sure the battery size is sufficient for the required backup and alarm time during
mains failures; use the calculation directions. See section Battery calculation, page 37.
Use a 12 V VRLA battery of capacity 100 - 230 Ah, marked with the type designation and
date of manufacture; use the supplied battery cables or similar for proper battery
impedance measurement. See section Battery and fuse, page 109.
Use the lifeline interconnections between the multifunction power supply and the
connected amplifiers to enable the snooze mode for sufficient backup and alarm time.
See section Lifeline, page 117.
Control input connections for alarm purposes must be supervised, using end‑of‑line
resistors, to detect a cable short or interruption and prevent that this is perceived as a
state change. See section Control inputs, page 123.
Emergency call definitions that are triggered from a control input must have a
preconfigured priority in the emergency priority range 224 - 255. Higher priorities
overrule lower priorities in case of resource or destination conflicts. In case of the same
priority the first call gets priority, but for priority 255 the last call gets priority.
To silence an audible warning from the CIE, control inputs must be configured for the
function to acknowledge and reset the fault alarm and voice alarm condition.
PRAESENSA control outputs are floating relay contacts without the ability to supervise
the control output connections. The control outputs should not be used as outputs to
fire alarm devices. Use control outputs of the CIE for that purpose. See section Control
outputs, page 124.
An uncertified PC, connected via the Open Interface, shall not be used as the sole user
interface to put the VACIE in the voice alarm condition.
The Open Interface is only allowed to be used as interface between a CIE and the VACIE
in case of the Smart Safety Link between the Bosch FPA 5000 CIE and the Bosch
PRAESENSA VACIE.
The Open Interface is allowed to be used with a PC on the same network for event
logging purposes, including the possibility to acknowledge and/or reset the fault alarm
condition and the voice alarm condition.
