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.

2.0 Cabinet Specifications 2.1 Surface Cabinets All cabinets are manufactured from 18SWG sheet steel and finished in satin texture epoxy powder stove paint. Top entry grommets and rear entry knockouts are provided.
2.2 Semi-Flush Bezels The semi-flush bezel locates to the rear of the bevelled edge of the back box, leaving the bevelled edge and door raised out from the wall. Finished in the same colour as the cabinet back box and fitted by means of pinch bolts, thus avoiding the need to drill the cabinet.
2.3 Fully Flush Bezel Fixed to the standard cabinet back box in place of the door and sized larger than the back box. Available in polished or brushed brass, stainless steel and painted finishes.

3.5 Use of Auxiliary Inputs Auxiliary inputs are provided to allow remote operation of the following functions: • Fault • Evacuate • Silence • Reset Each input circuit is fully monitored for open and short circuit faults. To activate an input a 680 ohm resistor should be connected across the input circuit by a normally open switch contact. Two switches are shown in Figure 1 although there is no limit to the number of switches.

4.0 Software Specifications 4.1 Overview of Engineers Functions This section describes an overview of the functions available to the end user. 4.1.1 Changing Time and Date The user can manually set the time and date although this should not normally be required. The current time is maintained by a dedicated battery when all power removed from the system. How to set the time and date is described in the user manual. 4.1.
Note: The default levels are: Default Alert level Default Fire level Valid Alert Levels Valid fire levels Default sensitivity levels Valid sensitivity levels XP95 sensor 45 55 35, 40, 45, 50 55, 60, 65, 70 N/A N/A Discovery sensor 45 55 35, 40, 45, 50 55 3 1, 2, 3, 4, 5 All ancillary devices have fixed responses except the Apollo Input Output module. The input for this device can be configured for response as a fire, fault, alert or indication only. 4.1.
The zone and group based events can occur on any device, or devices within the specified zone or group: • Fire in a group or zone, output cleared on silence alarms. • Fire in a group or zone, output cleared on reset. • Any two fires in a group or zone, output cleared on silence alarms. • Any two fires in a group or zone, output cleared on reset. • Alert in a group or zone, output cleared on reset. • Fault in a group or zone, output cleared on reset.

5.1.2 A1535/A1536 8 Way Expansion Boards Up to 31 (A1535 & A1536) 8 way programmable expansion boards may be connected to each Discovery 1-4 loop panel. A special 2 door cabinet is available to house up to 4 enhancement boards (details on request). Up to 31 boards in total may be connected via an RS485 comms - for local expansion only. Local power is required for each board in addition to the RS485 comms link.
The Discovery is approved with the devices listed in this section. The other compatible devices are listed in section 6.
