Siemens SIGMASYS C Manual page 51

The transponder (4STE control module) is used for connecting:
The transponder needs 4 addresses on the loop and a 24 V voltage supply from the fire alarm
control and indicating panel or a fault-monitored external power supply unit.
A distribution voltage failure does not lead to a loop crash (or interruption).
Application:
•
To connect special detectors, operating inputs and signals.
•
Ex-line connection (see "Fire alarm signaling in explosion-hazard areas"A24205-A331-
A292)
•
All detectors for threshold detector zones (MS 6/7, MS 9) and SIGMACON detectors
can be connected to SIGMALOOP via the transponder.
•
For control facilities with adjustable current up to 126 mA per output for direct connec-
tion of loads or connection via disconnected relays.
•
Programmable control pattern: static, flashing 1 s, dynamic.
If transponder outputs are programmed as control facilities, then these outputs are monitored
as monitored lines with a surveillance current of approx. 2 mA.
If an output is programmed with the "Control facility [VdS]" actuator type (as of Version 2.6),
then the output complies with the VdS 2489 guideline and is monitored for insidious wire
breakage and short circuits.
See Table 20: Technical data, voltage, current dimensions" on page 52 .
Every input and output can be programmed via SIGMAPLAN with an organisational address
and corresponding text assignment.
If the transponder is integrated in the SIGMASYS control and indicating panel or in the add-
on cabinet (4STE control module) and if power is supplied by the control and indicating pa-
nel's PSU, then the transponder is considered to be a signal processing unit. As a result, up
to four threshold monitored lines can be connected with up to 32 automatic or 10 non-
automatic detectors each. According to the guidelines (see 1.1), a maximum of 128 fire detec-
tors are allowed in SIGMALOOP.
If an external, fused power supply unit is used, a transponder input is required for the PSU
fault signals.
A total of 96 automatic or 30 non-automatic detectors can thus be operated on the 3 remain-
ing inputs.
If the power supply unit is not fused, a maximum of 32 automatic or 10 non-automatic detec-
tors may be connected for each transponder.
Powered inputs and outputs are signalled as a fault in the event of power failure.
The transponder SPF 3500 occupies four address on the loop.

- A separate detector zone must be created for
each monitored line (a detector zone must not
be assigned to multiple threshold monitored
lines)
