Notes
1. As much telephones as desired can be defined as doorphone extension. Thus,
in addition to the default doorphone terminal (110), various extensions can be
used as doorphone interfaces as well.
2. If the password for a doorphone extension is not defined as 250, then this
extension operates as a hotel room extension and this may lead to undesired
functionality.
3. The following principles apply for the calls of doorphone extensions:
a) If the doorphone used has a handset, when the doorphone extension lifts
the handset, he hears internal dial tone for a short while, then he receives
silence. If the doorphone is a phone without handset, then silence is
received continuously.
b) The doorphone extension can only dial numbers that start with digits “0”,
“1” and “2”.
c) If the called extension is busy, then the doorphone extension starts
hearing the dial tone after 4 seconds, in order to be able to dial another
number.
d) If the called extension does not answer the call within 6 ringing periods,
then the doorphone extension starts hearing the dial tone, in order to be
able to dial another number.
e) When there is an incoming call, the connection is established automatically
after a short tone.
4. The doorphone extension can also activate the door-opener, using other
extensions’ password. This facility enables door-opener control individually for
each extension, such that other extensions can use doorphone extension’s
telephone in order to activate door-opener. In order to do that, “Relay Code +
Relay Number + Extension Number + Password (of this extension)” must be
dialled.
5. A normal extension that is talking to the doorphone extension can activate door-
opener by pressing “#” with the following conditions:
a) If he has Intrusion Authority 0, he activates the relay on the system.
b) If he has Intrusion Authority 1, he activates the first relay on first RL04.
c) If he has Intrusion Authority 2, he activates the second relay on the first
RL04.
