Additional LSN features
The LSN non−automatic fire detector series 210 offers all the features of the improved" LSN
technology:
D Flexible network structures including T−taping" without additional elements.
D Up to 254 LSN improved elements per loop or stub line.
D Automatic or manual detector addressing can be selected via the rotary switch, in each
case with or without auto detection.
D Power supply of up to 300 mA for the connected elements via LSN.
D If using the LSN improved version" elements in conjunction with FPA−5000, unshielded
cable can be used. Otherwise, shielded cables must be used.
D Cable length up to 1000 m.
D Downwards compatibility to existing LSN systems and control panels in CL operating
mode CL00.
3. Planning notes
D Non−automatic fire detectors must be mounted visibly along escape and rescue routes
(e.g. exits, passageways, stairwells) and be easily accessible.
D An installation height of 1400 mm ($200 mm), measured from the middle of the push
button to the floor, must be maintained.
D Non−automatic fire detectors must be sufficiently lit with sunlight or another light source
(including emergency lighting if present).
D The distance between non−automatic fire detectors should not exceed 100 m according to
DIN 14 675 or 80 m according to VdS.
D In high risk areas, non−automatic fire detectors should be installed at intervals of max. 40 m
(VDE 0833 Part 2, Point 7.2.6).
3.1. Maximum number of detectors that may be connected
The maximum number of LSN elements (LSN interfaces and LSN call points) that may be con-
nected depends on their current consumption from the LSN data line. The limit values should
be taken from the product information supplied with the fire panel used.
3.2. Norms, guidelines and planning recommendations
Additional norms, guidelines, and planning recommendations with respect to installation loca-
tion etc. must be taken into account (see fire detector manual).
The regulations of the local fire services must be observed.
