3.7 Function of the activation unit

3.8 Function of the activation slave unit

(Manual)
1. The activation master pulls the deactivation request line (pin 14) to
ground potential after the activation of a transponder authorised for ac-
tivation.
2. This causes all deactivation units to start deactivating their locking cyl-
inders.
If the activation master recognises a positive deactivation
acknowledgement within ten seconds (deactivation acknowledgement
line becomes high-impedance), a potential-free contact between pin 5
and pin 7 is closed. A burglar alarm system connected to this can thus
be signaled that it can activate.
3. The activation master immediately disconnects this potential-free con-
tact between pin 5 and pin 7 after the renewed activation of a transpon-
der authorised for activation. This can be used to signal to a connected
burglar alarm system that it should deactivate.
4. The deactivation request line (pin 14) is then set high impedance again
by the activation master.
5. The burglar alarm system also sets the deactivation request line to high
impedance as soon as the alarm system is disarmed.
6. As soon as the deactivation request line is no longer highly resistive, the
deactivation units reactivate their locking cylinders.
If an authorised transponder is activated on an activation slave, the
activation slaves send an impulse (high-impedance mass-high-
impedance) to the activation request line (pin 14).
The activation master receives this pulse and informs the burglar alarm
system via the switch contact (see
alarm system can be activated.
