Chapter 2 Installation - First Use of System
34 Gem-5 User’s Manual
Access Key – Input: Input intended for a maintenance user to open barrier with a
key. It has the same functionality as Access Scanner – Input below.
Access Scanner – Input: Input intended for a user to enable a barrier (based on
Open Barrier below) to be opened by triggering a switch or relay. It can also accept
an Approach sensor. The voice file ACCESS.WAV is used when prompting for
Access Scanner – Input to be activated and F3 - Setup, F11 - Instructions, F1 -
Ready, Request Access setting is used when prompting for Access Scanner – Input
to be activated. In addition, if Access Scanner – Input or Access Key – Input is
assigned a terminal then it must be activated prior to monitoring even if it is not used
to open the Hot Side barrier.
Open Barrier: Specifies when barrier is to be opened. Requires Cold to Hot setting
above to be set before it can be changed. Note that there is no functional difference
between the “Normal” and “After Access Scanned” settings since cold side barrier is
always closed during background collection. “Normal” is same as “Leave Only” and
specifies that Cold side barrier is only open to allow occupant to exit when clean.
“After Access Scanned” implies barrier is closed until triggered. This can be Cold
Side Access Key – Input, Cold Side Access Scanner - Input. This initiates a Cold
Side sequence that opens the Cold side barrier until occupied. Once occupied, the
Cold Side barrier closes then the Hot Side barrier opens and occupant is asked to
leave. Once occupant has left, then Hot Side barrier closes.
