Safety Instructions
CAUTION!
Product components can become damaged by electrostatic discharge.
Wear a grounding wrist strap if you are working on the open PCB.
CAUTION!
Do not connect the grounding drain wire to grounding clips 3–4, because connection to the
grounding drain wire will raise a fault message to the BZ 500 and UEZ 2000 fire panels.
NOTICE!
The FCS-LWM-1 Heat Detector is intended for use with the DIN EN 54-5:2000 response grades
A1, A2, B, and C.
NOTICE!
The FCS-LWM-1 Heat Detector can be used in explosive zones 1, 2, 21, and 22. For notes on
installation in ex-zones, see
Page 10.
NOTICE!
The maximum monitoring height is 7.5 m. For rooms with higher ceilings a special VdS
authorization is required.
NOTICE!
Have maintenance and installation work carried out regularly by trained, qualified personnel
only. Bosch Security Systems recommends a functional and visual inspection once a year.
NOTICE!
Unusable electronic devices may not be disposed of with the household garbage, but rather in
accordance with the applicable regulations and directives (e.g. WEEE).

Short Information
FCS-LWM-1 is a linear heat detector for detecting fire. It is suitable for use in constricted
spaces and under extreme environmental conditions. The control unit reports temperature
differences by monitoring the resistance in the sensor cable. If the temperature rises, the
electrical resistance falls and the control unit outputs an alarm message depending on the
response temperature.
The response temperature for the MAX ALARM is set using a 16-position switch. If the
response temperature is exceeded, an alarm message is output. The differential alarm
threshold for the DIFF ALARM is set using two 16-position switches
–
–
DIFF TIME and
DIFF ALARM.
Located on the control unit are four LEDs, which display the status. The green LED signals
normal mode, the yellow LED a fault and the two red LEDs signal MAX ALARM and DIFF
ALARM.

The control unit features three keys. The two test keys TEST FAULT and TEST ALARM can be
used to test the system for fault or alarm. The RESET key restores the system to its original
status.
