1.0 Introduction and Typical System Illustration
The Discovery analogue addressable panel is available as a 1-4 loop panel using plug-in loop
driver cards. Each loop is rated at 500mA and will control up to 126 Apollo, XP95 or
Discovery devices. All addresses may be configured as cause/effect outputs, with up to 255
different programmable groups and 3 independently programmable output bits per address.
Discovery mode changes are configured by the panel’s internal clock and may differentiate
between weekday and weekend functions. Loop inputs may also be configured to change
selected loop devices between modes where temporary mode changes are required. Panels
are housed in well-designed enclosures and are finished in hardwearing epoxy paint.
The motherboard electronics are fixed to a detachable chassis thus facilitating a completely
empty enclosure for first fix installation. Top entry plastic grommets, bottom/rear entry
knockouts for mains, and rear entry knockouts are designed to assist with cable installation.
The Discovery has a 4 line x 20 character backlit LCD display, showing device address, zone,
type, status and location text. The LCD display is also used as a menu-driven engineers’
configuration display. User controls are accessed by means of keyswitch enabled membrane
controls, with password protection for engineer purposes.
32 zonal LEDs are provided as standard and “plug-in” printer is available as an option.
The panel provides 2 common fire changeover relays and 1 common fault changeover relay,
each rated at 1A, 30V DC. Four fully monitored panel inputs are provided for remote silence,
remote reset, remote evacuate and remote fault. The evacuate input will operate the general
alarms and may be programmed to operate the fire relay.
The Discovery panel may control up to 14 repeaters with full user capability via RS485 data
comms.
Extensive panel and network cause/effect programming is achieved via the PC programming
package.
Full networking with other Discovery panels, network repeaters and graphics package may be
achieved with an additional plug-in network driver card. Network cause/effect may be
programmed between Discovery panels, Nexus panels and active network repeaters.
