1.3.7 REMOTE STATION
Remote station switches can be used to change building modes without access to the Alto 818
terminal or host. Placed adjacent to a closed sensor-controlled entry, a valid privileged card is
needed to change the mode from closed to open. When exiting, the remote station switch is held
down while the card is presented to a sensor. When the switch is released, the building mode
changes to limited, allowing the card holder 60 seconds to exit the building before the mode
changes to closed.
CAUTION:
The card holder must check that all other personnel have left the building before using
the remote station switch to change the mode to closed. An alarm could be triggered
by anyone remaining in the building.
1.3.8 TAMPER SWITCHES
Tamper switches detect when the enclosure of a security device has been opened. A tamper switch
is built into each digital reader, keypad and the ACU. Triggering a tamper switch will cause a log
message to be generated and can be defined to activate an alarm.
