The Abacus Evolution comprises two models: the ICP G2 for eight to 64 zones in Grade 2 applications; and the ICP G3 model for eight to 256 zones for Grade 3 installations. Both models allow extra zones, memory modules and modems to be added (literally ‘snapped-in’) without the need – nor the associated disruption and cost – of replacing the whole unit. Abacus Evolution can be configured and expanded to handle up to 256 zones through the simple use of a modular bus-based snap-in expansion system. Abacus Evolution also meets and even exceeds the stringent false alarm requirements laid down by ACPO and the BSIA. All devices on the bus are easily visible, and optional communications are available to allow for remote servicing and maintenance. Also optional is a plug-in digi-modem and Automatic Maintenance Programme (AMP) that enable installers to test the panel remotely and produce a full diagnostic report. A particular benefit is that it removes one of the key headaches installers currently face – compliance to EN50131, as Jeremy Hockham, UK Managing Director of Bosch Security Systems explains: “The new European Norms are a challenge to installers when it comes to specifying and buying product. Stock can be a burden to carry, and training on individual kit time-consuming and expensive. Now it’s a simple choice between the ICP G2 and the ICP G3, and any future requirements from the customer can be easily accommodated.” Other features include proximity tags for Set and Unset (DD243) access control, full up and downloading via remote PC, a built-in calibrated Volts, Amps and Resistance meter for faster servicing, logging of up to 1,000 events, partitioning for up to 14 areas, 16 wards and 128 shunts groups, and timers for exit/entry. As well as normal alarms, the Abacus Evolution can also send SMS text messages to up to four GSM mobile phones. In addition to EN50131, Abacus Evolution can be configured to meet virtually any residential and commercial requirement to PD6662 and DD243 specifications.
