Modes of Operation
HRX proximity clock card terminals can operate in two modes of operation: intelligent and non-intelligent modes.
Intelligent mode consists of one HRX being defined as a Master with other HRX terminals on the same network being defined as Slaves. The Master terminal handles all communication with the software as well as validating and recording all clocking transactions made on any terminal networked together. The Master terminal stores employee names and badge numbers which it uses for display purposes and it keeps a log of each employee’s in/out status. The in/out status is used by the terminal when printing a fire alarm report via a hard wired printer and also for validation when used for access control. The majority of deployments use HRX terminals in intelligent mode.
Non-intelligent mode allows HRX terminals to record the clocking transactions simply as card numbers with a date/time stamp. The Focus software will subsequently assign the clocking transactions to the relevant employees. This mode has the advantage that the terminals do not need to communicate with each other and also employee details do not need to be stored in the terminal’s memory. Non-intelligent mode configurations are normally used in companies with distributed locations or for organisations who use a lot of temporary workers where it would be impractical to update the clocking terminal with an employees details before issuing them with a card.
Fire Alarm Functionality
When used in Intelligent mode the HRX3000 and HRX5000 terminals can be configured to automatically generate a fire alarm evacuation report when the fire alarm sounds. Both the 3000 and 5000 models include a set of inputs that can be wired to a fire alarm panel and/or a manually operated push-button. This acts as a trigger to start generating the evaluation report. The HRX3000 model has one connection available for a serial (RS232) printer while the HRX5000 has two connections.
We normally supply a specific serial laser printer that we know to be compatible and reliable. On occasion we have also connected an HRX to a dedicated TCP/IP network printer via a pair of RS232 to Network converters (creating an Ethernet tunnel).
It is also common for customers to request a UPS to power both the printer and the HRX terminal. This allows the fire alarm report to be generated during a mains power outage.
The HRX clock card terminals are supplied with an in-line regulated mains transformer supplying 9V DC. The transformer has screw holes to enable it to be fixed to a wall if necessary. The transformer has a standard UK 3 pin mains plug, however this can be removed for connection to a fused spur if required.
The HRX5000 can optionally be powered by a separate 12V boxed power supply incorporating a rechargeable 7Ah lead-acid battery. This will act as a UPS to the terminal during a power outage. Suitable boxed power supplies are available from Egress Systems and are normally held in stock.
The HRX5000 includes functionality to provide access control of up to two doors, barriers or turnstiles. Up to two separate remote proximity readers can be connected. There are two separate relays available to control the power to a door lock or to trigger a barrier or turnstile.
The HRX5000 does not directly supply power to a door lock. This must be supplied from a suitable rated power supply. The relays in the HRX5000 are used to switch the power to the lock.
Press-to-exit buttons can be connected to provide a timed trigger of each relay. Also, up to two door sensors can be connected to monitor if a door has been left open over a predefined period of time.
The validation of the access control is configured via the Focus software (Focus Pro & Enterprise only). As a brief explanation, employees are assigned to access groups. The access group will determine which doors all of the members of the group have access to as well as what times they can access those doors and on which days of the week.
