    Overview

    Details

    DIN-Rail Sounder Controller (5 Amperes)

    The DIN-Rail Sounder Controller (5 Amperes) is used to control the operation of a zone of externally powered sounders and report their status to the control panel.

    The DIN-rail Sounder Controller is loop powered and operates at 17–28V DC. It requires a local power supply of 12–35V DC to power the external load, which may be up to 5A. A polarising diode is required with each alarm device, as sounders are operated by voltage reversal, provided by a double-pole change-over relay. The sounder circuit is protected by a fuse rated at 5A (quick acting).

    Electrical Description

    The DIN-rail Sounder Controller is loop powered and operates at 17–28V DC. It requires a local power supply of 12–35V DC to power the external load, which may be up to 5A. A polarising diode is required with each alarm device, as sounders are operated by voltage reversal, provided by a double-pole change-over relay. The sounder circuit is protected by a fuse rated at 5A (quick acting).

    Operation

    The Sounder Controller allows sounders to be operated continuously or be pulsed, 1 second on, 1 second off. Sounders may be operated individually or in groups and, whichever address mode has been applied, may be synchronised when in pulsed operation.

    An opto-coupled input is provided to monitor the state of the external power supply.

    In normal operation the Sounder Controller returns a pre-set analogue value of 16, but in the event of an open or short-circuit fault or of a fault in the external power supply, the unit returns a pre-set analogue value of 4.

    Mechanical Construction

    The Sounder Controller is supplied in a housing which is clipped onto a standard 35mm DIN rail (DIN 46277) using end stops provided.

    Connections are made via plug-in terminal blocks which accept wires up to 2.5mm².

    Two LEDs are visible through the top cover of the enclosure.

    The red LED pulses or is illuminated to indicate that the sounders are, respectively, pulsed or switched on continuously.

    The yellow LED is illuminated whenever a fault condition has been detected.

    If the fault LED is not required or the extra loop current to illuminate it is not available, it can be disabled by using the eighth segment of the DIL switch.

    Device Addressing

    The address of the unit is set on segments 1–7 of the DIL switch. Segment 8 is used to disable the Fault LED if it is not required or the extra loop current to illuminate it is not available.

    The Sounder Controller is polled by the control panel either individually or as part of a group. Two DIL switches are provided to set the individual and group addresses.

    For more details refer to Installation Guide (39214-447).

    Backward Compatibility

    The unit will operate only with control equipment using the Apollo XP95 or Discovery protocol. The features of the Sounder Controller are available only when the unit is connected to a panel with the appropriate software.

    EMC Directive 2014/30/EU

    The DIN-Rail Sounder Controller (5A) complies with the essential requirements of the EMC Directive 2014/30/EU, provided that it is used as described.

    A copy of the Declaration of Conformity is available from Apollo upon request. Conformity of the DIN-Rail Sounder Controller (5A) with the EMC Directive, does not confer compliance with the directive on any apparatus or systems connected to it.

    Construction products regulation 305/2011

    The DIN-Rail Sounder Controller (5A) complies with the essential requirements of the Construction Products Regulation 305/2011/EU.

    A copy of the Declaration of Performance is available from Apollo upon request.

    Additional Information

    FAULT MONITORING

    In addition to the monitoring of open and short-circuit faults on the sounder wiring, the Sounder Controller has a facility to monitor the presence and polarity of the external power supply to the sounders. This is achieved by a circuit which includes an input to monitor a volt-free, normally-open contact. A wire link must be fitted if the fault contact is not used.
