External Detector Alarm Displays - Bosch FAP-O 500 Series Product Information

Product Information 500 Series LSN Fire Detectors (EU)

5.6. External Detector Alarm Displays

If the detector is not directly visible or was mounted in rooms that are inaccessible, an
external detector alarm display is used in the corridors or in the access routes to the
corresponding section of the building or rooms.
The red alarm indication (A) corresponds to DIN 14 623.
In cases where relay bases are used, no external detector alarm
display can be connected.
If unshielded cables are used, the cable length between an LSN
detector and an external detector alarm display is restricted to a
maximum of 3 m.
If shielded cables are used, make sure that the total cable length
(= sum of all cables leading to external detector alarm displays
within one loop or stub) does not exceed 500 m.
Mounting notes for the remote indicator FAA−420−RI
The remote indicator FAA−420−RI must be mounted so that the flat
side (A) shows towards the observer's line of sight.
