Apollo Intelligent Open-Area Sounder VID (White Body / Red Flash) (SA5501-351APO)

The Apollo SA5501-351APO Intelligent Open-Area Sounder VID (White Body / Red Flash) is designed for use in open areas and can be connected to any CoreProtocol, Discovery or XP95 system.

The Intelligent Open-Area Sounder VID includes features such as group, global and individual control, status reporting and selectable tone and volume settings, all configured through the fire control panel.

Sounder, visual indicator or both

The Intelligent Open-Area Sounder VID normally switches both sounder and visual indicator to provide an alert or evacuation signal. In situations where a flash or a sounder is not permitted, it is a simple choice as to whether to switch both sounder and visual indicator together or to switch either as necessary.

The right tone for the installation

The Intelligent Open-Area Sounder VID offers a choice of 15 evacuation tones , including the standard Apollo evacuation tone. A tone is selected during commissioning in order to suit local regulations or customs.

Whichever evacuation tone is selected there is a secondary tone which may be used for alerting or warning of a possible evacuation. 

The right level of sound

The sounder is set during commissioning to one of seven levels of sound, the highest level being nominally 101 db(A) at 1m.

At less than 60 db(A) the lowest level falls outside the scope of the EN54 standard. It has been included to provide a very local warning for the use of personnel in particular environments, such as nurse stations in hospitals.

Addressing

The Open-Area Alarm Devices respond to their own individual address which is set via the appropriate XPERT address card.  Group address and tones on CoreProtocol systems are set using the fire control panel.

Location-specific volume setting

Detectors and sounder indicators are installed in many different types of environment.

When configuring the Intelligent Open-Area Sounder devices the adjustment of the volume can be done at the point of installation.

The commissioning engineer simply sets the control panel to ‘Set-up’* and then walks from one device to the next to set the required volume, using a magnetic wand. When all devices have been set the engineer simply presses a button on the control panel which then registers all the individual volume settings.
