Power supply.
The B-TEL99 must be powered by 13.8 V
250 mA min.
Basic connections
The basic connections are necessary for the basic functions of the B-
TEL99, and are illustrated in figure 5 (highlighted lines) on the following
page. Figure 5 illustrates Alarm channel 1 connected to the normally
closed contact (NC) of the control panel alarm relay.
+
If the default programming (Positive drop) is to be changed to activation by
Negative command, the Alarm channels must be connected to an output
that goes to Ground (Negative) in the event of alarm (e.g. open-collector
output).
Auxiliary connections
The auxiliary connections are not necessary to the basic functions of the B-
TEL99, but offer further functions to this flexible appliance. The connections il-
lustrated in figure 5 are described in the following paragraphs.
Tamper
connection
The connection of the tamper terminals allows detection of tamper on the
B-TEL99 container. These terminals should be connected in series to the
tamper line of the alarm system, as shown in figure 5 .
Telephone-line
tamper
connection
The connection of the telephone-line tamper terminal signals telephone-
line tamper or cutting. Terminal 10[OUT] is available for connections to a
telephone-line switching device.
+
Terminal 10[OUT] is an open-collector output (NPN).
Device
connection
The B-TEL99 has two Alarm channels. Alarm channel 2 can be used for
the connection to the alarm relay of the fire alarm system, to the Duress re-
lay of the security system, or for the connection of a radio receiver (tele-
service). The connection example is shown in figure 5: terminals [COM]
and (NC) of the device relay must be connected to terminal 13[+12] and to
the secondary alarm channel 12[L2] of the B-TEL99.
Stop alarm
cycle/s
connection
By connecting terminal 8[B.A.] to Negative, it will be possible to stop the
alarm cycle/s. This feature is useful when:
Ø
the dialler is difficult to reach, for security reasons;
Ø
it is necessary to stop the alarm cycle/s when the Burglar system is dis-
armed.
