TERMINAL
DESCRIPTION
5
Positive power supply at 11-16 Vdc (typically 12-13Vdc)
4
Negative (earth). The terminal is duplicated on two terminals.
1
Digital. Used for interfacing other devices, when required (e.g. 170D -F) or for PC interface
(data download, access supervision or programming). Connected by means of a resistance
(820 ohm, removable) to an internal positive (12 Vdc, ~14mA)
RA-RB
Output n°1. Normally associated with a TOUCH1 reader. Corresponds to two
“voltage free ” contacts (normally open) of an internal relay (max0.5/1 A).
S2
Output n°2. Normally associated with a TOUCH2 reader. This is an “open-collector” output, i.e.
is earthed when activated (positive is external). To activate an external relay connect between
this terminal and terminal 5 (+12)
S3
Output n°2. Normally associated with a TOUCH3 reader. This is an “open-collector” output, i.e.
is earthed when activated (positive is external). To activate an external relay connect between
this terminal and terminal 5 (+12)
S4
Output n°2. Normally associated with a TOUCH4 reader. This is an “open-collector” output, i.e.
is earthed when activated (positive is external). To activate an external relay connect between
this terminal and terminal 5 (+12). As above but for touch 4
This is an “auxiliary” output as it can also be associuated with activation of the other 3 codes.
It is usually used for the accessory control of the courtesy light (activated together with the first
3 locks but at specific time intervals).
T1
Positive to connect to “probe” of touch number 1. The touch reader is connected between this
terminal (white wire) and earth (black wire). Multiple readers can be connected in parallel (all
with the same functions).
T2
Positive to connect to “probe” of touch number 2. The touch reader is connected between this
terminal (white wire) and earth (black wire). Multiple readers can be connected in parallel (all
with the same functions).
T3
Positive to connect to “probe” of touch number 3. The touch reader is connected between this
terminal (white wire) and earth (black wire). Multiple readers can be connected in parallel (all
with the same functions).
T4=CN4
Positive to connect to “probe” of touch number 4. The touch reader is connected between this
terminal (white wire) and earth (black wire). Multiple readers can be connected in parallel (all
with the same functions).
In this case the touch must be connected by means of a specific 2-pole connector.
TERMINAL BOARD LAYOUT:
The control unit has the following terminals: - 4 terminals for the connection of 4 code reading contacts (“probes”). The terminals
are marked T1 , T2, T3, T4 (the latter on a strip connector for local connection). NB: Connect the grey wire of the “probe” to ter-
minal T1-2-3-4 and the black wire to an earth terminal (4).
- 1 double terminal for output 1 , connected to the contacts of a N.O. type internal relay (terminals RA and RB) - 3 pilot outputs
for the same number of relays referable to outputs 2,3 4. (terminals S2, S3, S4)
- 2 12-16Vdc power supply terminals (terminals 4=GND, 5=+12) - Terminal 1 for digital communication (optional connection).
