It operates at 17-28V DC and is polarity-sensitive. Mechanical Construction\u003c\/p\u003e\n\u003cp\u003eThe Base is moulded in polycarbonate and has stainless steel contacts that accept solid or stranded cables of up to 2.5mm². Device Addressing\u003c\/p\u003e\n\u003cp\u003eThe Base responds to its own individual address set with a DIL switch. It also responds to a group address, set by means of a 4-segment DIL switch and to a synchronisation address which is embedded in the unit. Addresses 1 to 111 are used exclusively for individual addresses; addresses 112 to 126 are used for group addressing, while the synchronisation address, to which all units respond, is '0'.\u003c\/p\u003e\n\u003cp\u003eAny Beacon Base on a loop may be freely assigned to a group. The address for any group must be chosen from the range 112-126. Addresses 112-126 may be used as individual addresses but only if the 4-segment DIL switch is not used ie, group addressing is disabled.\u003c\/p\u003e\n\u003cp\u003eIf the 4-segment DIL switch were set to any number other than the default 127, a pre-set analogue value of 4 would be transmitted to indicate a fault. The Base is normally polled by its individual address. It responds as described below.\u003c\/p\u003e\n\u003cp\u003eIt is recommended that the synchronisation address '0' be sent by the control panel at regular intervals to align the internal clock of all sounders. The result is that the beacons are synchronised with each other when activated. NB: Units on two or more loops can be synchronised only if the panel transmits address '0' to all oops synchronously.\u003c\/p\u003e\n\u003cp\u003eGROUP ADDRESSING It may be desirable, in alarm conditions, to switch more than one base simultaneously. To enable this, devices may be controlled as a group and given a group address which is common to all beacon bases in the group. When a device recognises its group address, it will process the output bits but it will not return any data to the control panel on that ad dress.\u003c\/p\u003e\n\u003cp\u003eIf it is required to confirm the status of the outputs of devices under group address control, it is necessary to interrogate all devices in the group at their individual addresses. Backward Compatibility\u003c\/p\u003e\n\u003cp\u003eThe Base will operate only with control equipment using the Apollo XP95 or Discovery protocol. The features of the Base are available only when it is connected to a control panel with the appropriate software. Product Information\u003c\/p\u003e\n\u003cp\u003eThe Loop-Powered Visual Indicator is a local-area visual indicator designed for indoor use. The Visual Indicator has been developed as a supplement to sounders for use in situations where there is a risk that sounders will not be heard.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMore reliable than xenon visual indicators\u003c\/li\u003e\n\u003cli\u003eAutomatic LED check\u003c\/li\u003e\n\u003cli\u003eLockable\u003c\/li\u003e\n\u003cli\u003eWide angle of visibility\u003c\/li\u003e\n\u003cli\u003eEnables DDA compliance\u003c\/li\u003e\n\u003cli\u003eSynchronised flash\u003c\/li\u003e\n\u003cli\u003eCan be used with Discovery or XP95\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eIf you are matching this to an existing installation, work from the 55000-879APO part number rather than the description.\u003c\/p\u003e","brand":"USE_EXISTING","offers":[{"title":"Default Title","offer_id":57558663922037,"sku":"55000-879APO","price":47.67,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0050\/1216\/0612\/files\/55000-879APO.jpg?v=1788880541","url":"https:\/\/wmestore.co.uk\/products\/apollo-fire-open-area-beacon-55000-879apo","provider":"WME","version":"1.0","type":"link"}
