Questions & answers

Know before you buy

Quick answers about the PRA-CSLW, and how it compares.

Where does the PRA-CSLW fit?
The wall-mount call station of a Bosch PRAESENSA system: announcements, messages and music control from fire control rooms, security posts and receptions, connected to the [PRA-SCL] controller over the network.
PRA-CSLW or PRA-CSLD?
ModelMountingMicrophoneMic frequency rangeWeight
[PRA-CSLW]Wall / panelDetachable fist mic, omnidirectional, noise-cancelling500 Hz – 8 kHz1 kg
[PRA-CSLD]DesktopGooseneck, unidirectional100 Hz – 14 kHz0.9 kg
Both have the same 4.3" touch screen, PoE connection and support for up to four [PRA-CSE] extensions. Choose the PRA-CSLW for control rooms and noisy areas, and the PRA-CSLD for desks and receptions.
Do I need the PRA-CSE extension?
Yes, for most setups. Without a [PRA-CSE], the call station only works with pre-set zones. At least one is required for EN 54 voice alarm use.
How is it mounted?
Surface-mount in a wall cabinet or flush-mount in a panel. Optional adapters: PSP-D00097 (call station alone), PSP-D00098 (call station + [PRA-CSE]), and the PSP-D00099 5U 19" rack panel for control room consoles.
How is it powered and connected?
One shielded network cable carries audio, control and PoE power (IEEE 802.3af Class 3). Add a second cable for redundant network and power.
How does a PRAESENSA system fit together?
The [PRA-SCL] or [PRA-SCS] system controller is the brain: it routes all audio, plays messages and supervises every device. [Amplifiers], [multifunction power supplies] with battery backup and [call stations] all connect over one IP network using OMNEO, with loop-through cabling for redundancy. Up to 250 devices and 500+ zones per system, certified to EN 54-16 and ISO 7240-16.
Who supplies Bosch PRAESENSA in Pakistan, and what warranty do I get?
Electronic Security Company (ESCO) is the only authorized distributor of Bosch, Dynacord and Electro-Voice in Pakistan, so every PRAESENSA product we supply is genuine and comes with a 3-year warranty. Warranty is carry-in: bring the unit to an ESCO office and after inspection it is repaired or replaced as needed.
