Input and relay mapping
Note: Input and relay mapping does not apply to the NAC in IP Direct mode.
If the Network Access Controller is attached to a ChallengerPlus panel, then the
NAC can present up to 32 inputs for the ChallengerPlus to respond to and up to
16 relays for the ChallengerPlus to activate, without complex use of macros or
other programming.
These inputs and relays must be configured in the NAC via input and relay
mappings. The ChallengerPlus must also be programmed with additional inputs
and relays, with their numbering depending on the NAC’s address (set via its DIP
switches) and which ChallengerPlus system LAN the NAC is attached to.
Input mapping
Each input presented to the ChallengerPlus can reflect the sealed or unsealed
state of an input attached to the NAC (either directly onboard, or attached to a
DGP or RAS on one of its buses), or can reflect the state of a NAC door (e.g. a
Forced door condition).
An input mapping must be set up in the NAC to map the state of the input or
door to an input number in the range 1 to 32.
Each mapped input has a type, which may be one of the following:
Not used – the input always reports as sealed. This type of input cannot
be assigned to a door.
Forced – the input is a logical input associated with a door and is
unsealed when the door has a Forced Door alarm (from the door’s Door
input 1 being unsealed) or there is a tamper condition.
Egress – the input is a logical input associated with a door and is
unsealed when the door is in egress condition (i.e. the door’s Egress
input is unsealed) or there is a tamper condition.
DOTL – the input is a logical input associated with a door and is unsealed
when the door has a Door Open Too Long (DOTL) alarm (from the door’s
Door input 1 being unsealed).
Shunted pass through – the input is a physical input which is passed
through to the ChallengerPlus panel if the associated door is not shunting.
Direct pass through – the input is a physical input which is passed
directly through to the ChallengerPlus panel. This type of input cannot be
assigned to a door.
Note: NAC inputs are masked from the ChallengerPlus if they are not mapped.
Input mapping is programmed in CTPlus on the Input/Relay mapping tab of the
DGPs form for the NAC. See the “Programming input and relay mapping” section
on page 79 for instructions.
