6.3.39 Transmission Failure
The integrated communicator triggers this input if a message via the Sintony com-
municator SML 51/61 can not be passed on. The triggering depends on the "Num-
ber of calls" parameter (TM65). A transmission fault can be reset by a valid PIN.
Refer also to "Transmission fault" input type. Also SMN42 will be supervised.
6.4 Physical
Type
The following physical input modes are available:
Normally open contact
Normally closed contact
Normally closed contact monitored
Alarm and Tamper monitored
Fire
Glass break sensor
Emergency exit
Radio alarm
Not all modes are available; it depends on the central control unit variant.
1. Normally open contact
The input is operated without a terminating resistor. Therefore the input is only checked for
triggered (closed) and normal states (open).
Input normal state = open
Input triggered = closed
Positively in normal state at > 6.8 k
Ω
(6.5 V)*
Positively triggered at < 6.6 k
Ω
(6.4 V)*
*The voltage values apply for a mains power supply of 13 V
2. Normally closed contact
The input is operated without a terminating resistor. Therefore the input is only checked for
triggered (open) and normal states (closed).
Input normal state = closed
Input triggered = open
Positively in normal state at > 6.2 k
Ω
(6.2 V)*
Positively triggered at < 6.6 k
Ω
(6.4 V)*
*The voltage values apply for a mains power supply of 13V
3. Normally closed contact monitored
(1 EOL)
The input is operated with a 4.7 k
Ω
terminating resistor. This means that the input is triggered
either on opening or short-circuit. It is in the normal state if a resistance of 4.7 k
Ω
is present at
the input.
Input in normal state = 4.7 k
Ω
(1R)
Input triggered = open or short-circuit
Positively in normal state from 3.6 k
Ω
(4.5 V)* to 6.2 k
Ω
(6.2 V)*
Positively triggered at < 3.3 k
Ω
(4.2 V)* or at > 6.6 k
Ω
(6.4 V)*
*The voltage values apply for a mains power supply of 13V
4. Alarm and Tamper monitored (2EOL)
The input is operated with two terminating resistors each of 4.7 k
Ω
.
In this mode, an alarm contact and tamper contact can be monitored simultaneously via one
input. Whereas the contacts must open in the event of an alarm or tamper state, a short-
circuit of the input is also evaluated as tampering.
Tampering triggers the synthetic “Tamper” input in the corresponding partition and this occurs
regardless of the input type chosen.
If an input which is programmed to two terminating resistors is bypassed, this switches off
only the alarm but not the tamper facility. The same applies to the soak test.
Input in normal state = 4.7 k
Ω
(1R)
Input triggered = 9.4 k
Ω
(2R)
Input in tamper state = open or short circuit
Positively in the normal state from 3.6 k
Ω
(4.5 V)* to 6.2 k
Ω
(6.2 V)*
Positively triggered from 8.0 k
Ω
(7.0 V)* to 10.5 k
Ω
(7.9 V)*
Positively in tamper state at < 3.3 k
Ω
(4.2 V)* or at > 11.6 k
Ω
(8.2 V)*
*The voltage values apply for a mains power supply of 13V
