6.4.3 Zone Doubling
The number of zones can be increased with zone doubling. If 2KΩ and 3.9KΩ resistors are connected
to inputs Z1, Z2, ....., Zn as follows and programmed accordingly, zone doubling is performed at that
input. Thus, two zone connections are made, one being the connected input (Z1, Z2, ....., Zn) and the
other pair (Z9, Z10, ....., Z (n + 8)). The input reaction of all zones can be individually programmed as
NC or NO. Eamples of zone doubling is shown below. Zone doubling is not available when additional
zone modules are used. Below are examples of zone pairing with and without tamper.
PS: If a single end-of-line, double end-of-line resistor connection or zone doubling is made as
shown in the above figures, the system will alarm when the tamper is opened while the panel is
armed. If the panel is not armed, the system only warns of zone failure.
See section 7.5.1 Zone Connection Type for programming details.
6.5 KEYPAD CONNECTION
The keypad connection of the panel is made with 12V, A, B, GND terminals of keypad terminal group.
The 12V, A, B, GND terminals on the keypad should be connected to the same terminals on the panel
board. If there is a problem with the keypad connection, the keypad will warn you. It is
recommended to connect the shield on the keypad cable to the EGND on the panel and keypad sides.
4 keypads can be connected to TSP-5XXX panels. Keypad addresses must be given first when
connecting multiple keypads (To assign the keypad address, see section 7.10 Learning the Keypad
Address - Changing). In addition, the keypads must be activated in the program. (See section 7.6.1
Keypad Authorizations).
!!! WARNING: When connecting the keypad or replacing the keypad, make sure that the panel is
de-energized and terminals A, B do not come in contact with 12V. Otherwise, the panel may
malfunction.
