The Convert-A-Card from Security And Fire Electronics is designed to permit your customers to continue using their original cards and readers when part of the system has been changed. It does this by converting the format of the original cards to the format of your system. Your system then recognizes its own format, in addition to other formats. The unit can also be used for selected (or all) readers in your system, to permit entry to users from another system. The unit is transparent to the host system. Installation time is negligible, and there is no system reprogramming or modification necessary.

The Convert-A-Card, from Security And Fire Electronics, Inc. allows card reader systems (as well as proximity, keycard, or *Dallas Touch Memory^TM reader systems) to recognize and accept the protocols of other systems. It does this by transparently converting the readers' protocols to the format of the host system. The Convert-A-Card is simply and easily installed between the card reader and the system's card reader inputs. No reprogramming is necessary since the presence of the Convert-A-Card is not detecable by the host system. The Convert-A-Card causes no noticeable delay in the system's operation. When a card of the host system's original format is read, it is passed on to the host unchanged.

Each Convert-A-Card can accept two readers. It is controlled by a small, state-of-the-art microprocessor, and is fully backed up with a hardware watchdog for totally reliable operation. It is powered by the host system supply, and requires only 10-15 ma at 5-24 VDC to operate. The Convert-A-Card is transient protected on all inputs and outputs. Each Convert-A-Card is customized to convert between customer-specified formats.

The SAFE DCU-4 is a single-gang-size CPU-based board that emulates the output of a wiegand card reader. This device can be used as a replacement for a wiegand card reader in low to medium security areas, or as an additional security measure in high security areas. The output format is 32-bit, 26-bit or custom programmable. The SAFE DCU-4 fits in a single-gang box and has two LED outputs. It also has a tone beep for data entry. When the digits are pressed, the device assembles them into a simulated wiegand card format and sends it to the RIM or card reader interface. It is powered from 12VDC and draws about 35 ma of current.

The SAFE RLI is a plug-compatible interface replacement for modem cards 900307 and 900181, used on the DCP-200 and KDR-1000, manufactured by Thorn Automated Systems, Inc.
It is packaged as a dual board set. Its purpose is to convert the DCP or KDR into a device that will respond to RIM protocol at 300 or 1200 baud over a 20ma loop (with redundant line capability) instead of the DCP protocol and FSK modems.
The RLI uses one RIM address for every two DCP codes in a cabinet. That is, an RLI reports 32 inputs per RIM address (which is equal to two DCP's.) The RLI monitors up to 4 RIM addresses (which is 8 DCP's - the maximum in a KDR-1000.).
Additionally, each input point can be inhibited from the KDS computer by activating the associated RIM output point.

The RLI continuously monitors the integrity of the incoming loops. If one of the loops between the RLI and the KDS is/becomes defective, then the RLI will send an alarm to the KDS, to indicate this. There are three alarm conditions for each loop. A "line fail" message is sent if a loop is open or shorted. A "no communication" message is sent if no data has been received in 4.5 minutes. A "line noise" message is sent every time 250 errors are detected. (The RLI statistically analyzes the quality of data received on each loop and informs the KDS if excess errors (250) are detected.) By computer output command, this can be changed to every time five errors are detected. The RLI samples both lines. A "no communication," or "line fail" condition causes the RLI to automatically switch to the good loop.

The SAFE Inteligent Loop Dropout Panel (SILDP), automatically monitors RIM loops. Its primary benefit is that it permits the addition of many miniloops to a main RIM loop -- with no danger of losing everything on a loop due to one device or miniloop line failure. The SILDP has 16 zones, each capable of monitoring, shunting or restoring the outgoing and incoming leg of a miniloop. Each zone is capable of automatic or manual operation. There is a 3-position switch for each zone, which determines the mode of operation, and a per-zone, bicolor LED showing the current status of each miniloop. With the switch in the center positon, operation is automatic and the LED indicates the status of the loop (green is good, red is fault). With the switch in the up position, the miniloop is locked into the main loop whether the miniloop is good or bad, and the LED flashes green to indicate this condition. (This allows diagnostic work to be done on the system. With the switch in the down position, the miniloop is manually shunted out of the main loop and the LED flashes red.

In normal operation the SILDP does not interfere with its miniloops. It only monitors the communications going into the miniloops and the communications coming back on the return legs. While the communications are normal, the zone LED is green indicating a normal loop. If the SILDP detects communications going into a miniloop but nothing returning, it knows that that miniloop is broken. The SILDP then shunts that miniloop out of the main loop and lights the red LED indicating that miniloop is bad. This restores the rest of the main loop. Meanwhile, the SILDP begins talking to the bad miniloop with the same communications format the host computer would use for a bad loop. The entire detection and switch over process takes about 1-1/2 minutes. If the miniloop problem is corrected, the SILDP automatically detects it, and restores the miniloop back into the main loop again.

The SILDP is designed to fit into a standard 19" rack and occupies only two inches of vertical space. Connections are made through two 50-pin telephone-type connectors. To facilitate connection to existing systems, an interface panel is available that plugs into the two 50-pin connectors. RS232 connectors and cables are then connected directly to the miniloop modem. This assures minimum downtime while installing the SILDP.
