Introduction to i-on10Page 10Detectors (zones)Detectors are the physical devices that detect alarm conditions. A zone is the lowest-levelitem within the intrusion system that can be set or unset.Detectors supported by i-on10 include:XCELWXCELWPTDETWDT-G2DET-WDTPT-G2DET-RSDCM12Note: Although it is possible to connect detectors in series and therefore to have morethan one detector in the same zone, it is not normal practice. Instead, there is normallyonly one detector per zone and for this reason, detectors are often referred to as "zones"within the intrusion system.Wired detectors connect using standard alarm cable to the i-on10. Please refer to page 14for details of the different wiring methods you can use.Note: If 4-wire CC wiring is used, this may reduces the available number of zones to 5,unless an ADP-10CC board is fitted.All wired detectors with contacts that open and close are supported, as there is no protocolinvolved.Plug-by (digital communicator)The i-on10 includes an 8-output plug-by communicator port, which allows the system tocommunicate externally to an alarms-receiving site using a separate digital communicator(purchased separately).By default, the outputs are switched negative (from 12Vdc to 0V) when active. You canprogram these outputs to be switched positive (from 0V to 12Vdc) when active.Output deviceA device such as an indicator, lighting system or third-party item of equipment can beswitched on or off using the transistor (open-collector) output available on the i-on10 PCB.You can configure the output in the Installer menu to control the external device when, forexample there is an alarm in a specified zone.By default, the output is switched negative (from 12Vdc to 0V) when active; you canprogram it to be switched positive (from 0V to 12Vdc).SoundersSounders indicate alarms, entry tones, exit tones and other conditions. There are varioustypes of sounder: Keypad sounders − A sounder is built into each keypad. External wired siren/strobe unit − The i-on10 provides connections to drive astandard wired siren/strobe unit in Self-Activating Bell (SAB) or Self-Contained Bell(SCB) mode. The Scantronic SDR-WEXT-G2 siren/strobe unit is supported, as areother third-party units that have compatible connections.
