7. Seizure Relay Option
A seizure relay is available as an additional component inserted in series with the a-b
connection. The floating output contact K4 is closed from the time the
key is pressed, until
the end of the call.
8. Day/Night Switch Option
EXICALL can now be programmed via menu item no. 143 so that the ext. C/A contact K2 is
defined as a DAY/NIGHT switch. When contact K2 is open (day) pressing the call button
dials the first number; when contact K2 is closed (night) the second number is dialled
instead. If there is no reply or the number is engaged, the night number is called during the
day and vice versa, or neither number is called (depending on the selection under menu item
274).
9. Explosion Protection, Zone 2, T1 - T6
According to SN-SEV 1000 (NIN), EXICALL type NIT 960 may be used in zone 2 and in gas
groups IIA, IIB and IIC, where there is an explosion hazard due to flammable agents in the
T1 to T6 temperature class range.
For information and special conditions, users and electricians should refer to the appendix to
certificate A. No. 96.1 10403 published by the Swiss Electrotechnical Association and the
Federal High Voltage Supervisory Board.
