If more than one KEYPAD is connected in a cascade layout, use a
single cable without ever interrupting the shield.
!
Operation is not guaranteed for distances of over 30 m
between the KEYPADS or READER and the DECODER.
The electrical connection between READER or KEYPAD and the
DECODER comprises two conductors carrying a coded signal, so any attempt
to force or break into these two conductors will have no effect.
The DECODER can be powered with 12 or 24V alternating or direct
current.
It has 2 outputs commanded by normally open (NO) relay contacts;
if a normally closed (NC) contact is required, cut point "A" (Figure 7)
10
and join point "B" with a spot of solder.
The output relay is "momentary", that is, it activates as soon as a valid
CARD is identified and deactivates when the CARD is removed from
the READER (for the KEYPAD, when the activation key is pressed
and released).
The TIMER function (the output remains active for the set time), the
BISTABLE function (at the first command the output activates, at the
second it deactivates) or the ANTI-THEFT function can be obtained
by means of appropriate programming (see the "Programming output
in the ... mode." function). The anti-theft function features the
BISTABLE mode on output N°1 (to activate or deactivate an anti-theft
system) while output N°2 gives an impulse when the system is
activated and two impulses when it is deactivated (for use as an
acoustic or visual signal).
