Apollo XP95 Beacon Base with Isolator - 45681-333APO

Apollo XP95 Beacon Base with Isolator - 45681-333APO

Apollo XP95 Beacon Base with Isolator - 45681-333APOThe Visual Indicator Base is a loop-powered visual indicator combined with a standard Intelligent Mounting Base. It is used to signal a fire alarm in enclosed areas. The visual indicator base can be used with either a detector fitted or with a cap as a stand-alone alarm device. The base is loop powered so needs no external power supply. It operates at 1728V DC and is polarity-sensitive.Device AddressingThe 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. Any Beacon Base on a loop may be freely assigned to a group. The address for any group must be chosen from the range 112126.Addresses 112126 may be used as individual addresses but only if the 4-segment DIL switch is not used ie group addressing is disabled. If 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. It 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.Key FeaturesVisual indicator flash rate of once per secondSynchronisation of visual indicator flashIndividual and group addressingUnique visual indicator self-testLoop-poweredBuilt-in Isolator

To enable this sounders may be controlled as a group and given a group address which is common to all sounders in the group. When a device recognises its group address it will process the forward command bits but it will not return any data to the control panel on that ad dress. If 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.CommunicationXP95 Discovery and CoreProtocol compatibleBackward CompatibilityThe features of the Integrated base sounder are available only when the sounder is connected to a control panel with the appropriate software.

Apollo Orbis I.S Multisensor with Flashing LED ORB-OH-53028-APOThe Orbis IS Multi-sensor Smoke Detector benefits from the same false alarm technology as the Optical Smoke Detector with the addition of a heat sensing element.InstallationIt is important that the Orbis I.S. detectors be installed in such a way that all terminals and connections are protected to at least IP20 when the detector is in the base. Special care must be taken with the rear of the mounting base where live metal parts may be accessible. Flush mounting of the base on a flat surface will provide the required degree of protection.The conduit box available from Apollo part no. 45681-204 is also acceptable for mounting I.S. bases. Apollo also supply a range of deckhead mounting boxes.

XP95 products are frequently used in commercial industrial financial government ITtelecoms and healthcare applications.The new Apollo XP95 EN54-112001 compliant Manual Call Point MCP is based on the KAC conventional MCP range. It is electronically and mechanically backward compatible with previous Apollo call points based on KACs World Series product. The address of each call point is set at the commissioning stage by means of a seven-segment DIL switch.A single bi-coloured alarm LED is provided on the call point. This LED is controlled independently of the call point by the control panel. The red LED is lit when the call point has been activated. An amberyellow LED indicates a fault. Call points can be remotely tested from the panel by transmission of a single bit in the communications protocol. Call points respond by providing a value of 64 which corresponds to the alarm value.The choice of detector from the XP95 range follows well established principles of system design. The optimum detector type will depend on the type of fire riskfire load and the type of environment in which the detector is sited.Key FeaturesA seven-segment DIL switch enables the addressing of each call point at commissioning stageWhen operated the manual call point interrupts the polling cycle for a fast responseBi-coloured LEDs indicate isolate and normal conditions
