2 System Overview

2.1 System Description

2.1.1 Operational Primer

The interface module is a fully supervised, addressable SDI bus device that allows access

control integration for the D9412 Family (8 doors) and D7412 Family (2 doors) control panels.

Each interface module can store up to 999 user tokens, each with a different access level for

each door. Authority for access is controlled by the level of the user, the time of day, the state

of the door and the armed state of the area to the interface module. Each of the authority

restrictions can be controlled through automatic and manual functions.

Users can be added to the system either by local programming using the Remote

Programming System (RPS), D5200, or by adding tokens using the Add User function through

the control center.

The interface module is not programmed using a local or remote programmer. The interface

module must be connected to the SDI bus to function properly and receive operational

programming parameters and user data.

2.1.2 Outputs

Dry contact SPDT relay for 12/24 V strikes. The relay provides a Normally Closed (NC),

Common (input voltage) and Normally Open (NO) output. When the relay is energized, the

outputs switch to an opposite state.

12 VDC. Provides a connection for a 12 VDC reader or a 12 VDC buzzer.

2.1.3 Inputs

Supervised zone input for the door contact. The zone input on the interface module is used

for the door contact that is physically mounted on the door to which the strike is connected.

The input can be configured for shorts or opens on faults but is normal only when the 1000 kΩ

EOL (end-of-line) resistor is in the circuit.

Unsupervised tamper input. The unsupervised tamper input is normal when open. Upon a

short, the point number assigned to the supervised zone is reported as a MISSING PT###

report.

Unsupervised Request to Enter [RTE] and Request to Exit [REX] inputs. The [RTE] input

and [REX] input are normally open inputs sharing the same common terminal. When

momentarily shorted (500 ms) by a dry contact, input will initiate the door sequence. Typical

applications include a N/O momentary push button or a N/O momentary relay activation from

a Door motion detector device.

The [REX] input generates Door Request to Exit and is used to exit the area assigned to the

interface module without having to use an identification. The [RTE] generates Door Request

to Enter and is used to enter the area assigned to the interface module.
