The Multi-tone Open-Area Alarm Devices are powered directly from the loop and need no external power supply. They operate at 18 -28V DC and are polarity sensitive.
Synchronisation of the tones ensures the integrity of the signal - tones from different sounders do not merge into one signal that could be mistaken for a different tone.
A nominal sound output of 100dB(A) is achieved at a current consumption of 5mA in the case of the sounder and 9mA for the sounder beacon. Many control panels will be able to drive up to 20 sounders per loop on average. The maximum number of sounders that may be connected to a particular loop should, however, be determined by a loop loading calculation using the Apollo Loop Calculator.
Since the Multi-tone Open-Area Alarm Devices are intended for use in open areas, it is possible for more than one sounder to be audible at any given point in a building. For this reason, the operation of all the sounders may be synchronised by sending address '0' in exactly the same way as for the XP95 Sounder Control Unit. Not only that, the Multi-tone Open-Area Alarm Devices can be assigned group addresses as well as individual addresses, so that the functional options of the sounder are identical with those of the Sounder Control Unit.
The Multi-tone Open-Area Alarm Devices are fitted to the mounting surface with four screws. The weatherproof versions have an additional square backbox and there are three drill centre points for cable entry marked on the upper and lower face.
The Multi-tone Open-Area Alarm Devices responds to their own individual address set with a DIL switch. They can also respond to a 'Group Address' which allows multiple sounders to be controlled simultaneously. A group address may be any spare address between 112 and 126 and is selected by means of a 4 segment DIL switch. An Alarm Device under group address control must have an individual address between 1 and 111 otherwise a fault value of 4 is transmitted. Alarm Devices not using the group address facility may be addressed at any address (1-126).
The devices will operate only with control equipment using the Apollo XP95 or Discovery protocol. The features of the Multi-tone Open-area Alarm Devices are available only when the sounder is connected to a control panel with the appropriate software.
The Weatherproof Multi-Tone Open-Area Sounder Visual Indicator is designed for use in outdoor open areas and can be connected to any Discovery or XP95 system. The sounder visual indicator complements Apollo's intelligent and integrated base sounders as well as the Multi-Tone Open-Area Sounder.
