Wiring And Balancing Alarm Detectors - INIM SmartLink Advanced Series Installation And Programming Manual

Installation and programming manual
The wiring and respective balancing method depend on the type of
detector you are installing, and the level of protection you wish to
achieve. The detectors can be powered through:
• terminal [+AUX/12V] and [-/negative] present on the PCB
• from any ancillary 12V power source as long as it has a ground
reference (GND) in common with the ground reference of the
SmartLinkAdv
The resistors used for balancing are:
• 3K9Ohm 1/4W
• 6K8Ohm 1/4W
The following table indicates the protection level of each detector
type and the balancing options provided:
BALANCING
Infrared or
Double technology
Magnetic contact
(*) The level of protection of Single balanced mode is as secure as
Double balanced mode if the tamper contact of the detector is
connected to a balanced zone on the SmartLinkAdv.
For N.C. (normally closed) and N.O. balancing
(normally open), it is possible to detect two distinct
zone conditions:
• standby
• alarm
For each of these the SmartLinkAdv reads different
values of the equivalent resistance on the terminal,
shown below in Ohm:
