Popularity of Sur-Gard MLR2 multi-line digital receiver set to continue

As a principal development resource for the DSC Group, SUR-GARD’s alarm communications technology is incorporated into a diverse array of products marketed under the DSC and SUR-GARD nameplate. Known as one of the most successful manufacturers of digital receivers in the world, SUR-GARD will be entering the millennium with a feature-rich digital receiver, MLR2 which now incorporates even more features than before.

Separate liquid crystal displays, micropro­cessors and power supplies for each of the line cards and for the CPM2, combined with ­special programming, means total line card independence. They can even keep working with the CPM2 removed from the rack in manual mode. Each line card has two separate circuits to decode the pulse/tone data. The user or the ­microprocessor can determine which gives the best results for weak signals.

Growing with the MLR2

• Expandable to 14 lines (total of 7 DRL2A modules).

• Program memory space to spare-capacity to meet new demands and decode new formats, growing and changing with the needs of modern monitoring requirements.

• Generous data memory allows for large event buffers and easy, flexible user programming.

Control flexibility

• Choose the handshakes you want, and in what order.

• Tailor the output to the computer.

• Change the printer and computer output to be full time, back-up, or not used.

• Customising is done from the keypad and front panel switches or remote via serial port.

Diagnostics

• All programming can be verified on the LCD display or printed.

• Printer events, computer events and call display records can be examined on the LCD and copied to the printer.

• The CPM2 polls each line card regularly.

• Line cards supervise the CPM2 polling.

• The printer is checked for presence, paper out, etc.

• The computer communication is verified with heartbeat test signals. Signals are buffered ­during computer outages.

Security

• 16 master and operator passwords.

• Operator acknowledge with time/date printed and advised to computer.

Verification

• Two-way audio.

• Downlook video verification.

• Built-in Caller-ID display, gives the phone number from which the call originates. ‘Ghost’, mis-programmed, or malfunctioning diallers, as well as wilful interference can now be traced.
