Auxiliary Connections - Bentel Security B-TEL99 Manual De Instalación Y Usuario

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 illustrated in figure 10 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 10.
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.
F
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 relay of the security system, or for the connection of a radio receiver
(teleservice). The connection example is shown in figure : 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:
l
the dialler is difficult to reach, for security reasons;
l it is necessary to stop the alarm cycle/s when the Burglar system is disarmed.
In the first case (dialler difficult to reach) connect a button or pulse lock between terminal 8[B.A.] and terminal 9[M]
as illustrated in figure. In the second case (to stop alarm cycle/s when the Burglar system is disarmed), terminal
8[B.A.] can be connected to terminal [+ON] of the Burglar system (a terminal with Negative when the system is
armed), or to terminal [+OFF] of the Burglar system (a terminal with Positive when the system is disarmed). In the
latter case, a 1k5, 1/4 W resistance between terminal [B.A.] and [M].
