Control equipment
Unless installed in an enclosure of at least IP65 rating, all equipment must be sited indoors and MUST NOT be
subjected to conditions likely to affect its performance, such as damp, salt air, water, extreme temperatures, physical
abuse, etc. As far as practical, control equipment should be located where background noise is normally low
(preferably not more than 40 dBA).
If an additional enclosure is used for any component, care must be taken to ensure that the functionality of the
components is not impaired. For example, all indicators must be visible and necessary tones must be audible at the
levels required by BS 5839-9 when the door is closed.
The MCU/LCU must be wall mounted at an easily accessible height, with the LCD at eye level, typically 1.4 metres
above final floor level and should be located in areas of low fire risk, usually in the control room.
Outstations
Type A outstations should be located at entrances and fire fighting lobbies and normally mounted 1.3 m to 1.4 metres
above final floor level. Type B outstations should be located in disabled refuges at each storey exit and normally
mounted 0.9 to 1.2 metres above final floor level.
As far as practical, outstations should be located where background noise is normally low (preferably not more than
40 dBA). Where there is a higher level of background noise, the installation of an acoustic hood around the outstation
may help to reduce the effect of background noise to an acceptable level
Disabled persons toilet alarm (DPTA) System
Refer to the documentation supplied with the DPTA (Part No. NC951).
Outdoor installations
Outstations may be mounted in an IP65 enclosure with an easily opened door. Steps should be taken to ensure that
moisture does not enter and damage the electronics and that necessary functionality is not impaired.
Sports stadiums
In sports stadiums, Type A outstations should be located no more than 30 metres from stewards’ positions, or other
normally manned areas as listed in the Guide to Safety in Sports Grounds. If they are exposed to the elements they
should be mounted in an IP65 enclosure with an easily opened door. Steps should be taken to ensure that moisture
does not enter and damage the electronics and that necessary functionality is not impaired.
Strobe driver module (part no. SDM)
If the ringer is not loud enough a flashing red strobe light and/or sounder may be fitted to any outstation.
A strobe driver module, part number SDM should be connected across the line to sense when the outstation rings.
An external 12 VDC EN 54 power supply must be connected to the strobe module to provide power for the module
and/or sounder. This may be provided local to the outstation, or centrally, in which case two extra cores will be
required and voltage drop should be taken into account.
