Repeater Panel Location The panel should be sited at a height where it is easily accessible and in a prominent position within the building. This means in most situations that the LCD should be at eye level.
Fire alarm panels (standard Kentec) with LCD display should be mounted such that the top of the panel is at 1.65 metres +/- 0.1 metres above floor level.
Installation of fire alarm panel shall be not exceed six feet in height measured from the floor to the top of the unit.
While installation heights are not specifically mentioned in most manufacturer's printed installation instructions, we would recommend that you install these modules not higher than 1800 mm above the finished floor (for ease of access).
Repeater panel require four wires from the main control panel and four wires onto other repeater panels if fitted. Wiring can be standard fire alarm cable such as FP200 or shielded data cable.
Repeater Panel Location
The panel should be sited at a height where it is easily accessible and in a prominent position within the building. This means in most situations that the LCD should be at eye level.
Some of the disadvantages of repeaters are that they can't separate the device in the collision domain, can't connect networks of different architectures, can't reduce congestion, etc.
NFPA 72 sets standards for the minimum and maximum mounting heights for fire alarm control units. The devices must be located between 1.5 and 5.5 feet above the finished floor to provide maximum accessibility. The recently revised standards make elevator recall and evacuation operations more specific.
Isolators should be placed at a height of 1.3m in general, however, this will depend on the 32 amp rotary isolator being controlled.
A minimum of 36-inches clearance in front of the panel must be maintained from the floor to 6-feet, 6-inches above the panel, or to the top of the panel whichever is highest. A minimum of 30-inches clearance from side to side must be maintained in front of the panel.
The simple answer that the operable part of the pull station needs to be at least 42 in. (1.07 m), and not more than 48 in. (1.22 m), above the finished floor. Additionally, one pull station needs to be within 5 ft (1.5 m) of each exit doorway on each floor where required to be installed in a building.
NFPA 72 requires all fire alarm systems, including equipment used for monitoring, to have 24 hours of backup power. If an IP communicator is used for monitoring, the internet equipment must be connected to a backup power supply capable of providing power for a minimum of 24 hours.
Preferably in an area of low fire risk and on the ground floor by the entrance used by the Fire Brigade and preferably viewable from outside of the building. It should be located in an area common to all building users and where automatic detection is in use, the Control Panel should be in a protected area.
Wall-mounted alarms should be installed not more than 12 inches away from the ceiling (to the top of the alarm). If you have ceilings that are pitched, install the alarm within 3 feet of the peak but not within the apex of the peak (four inches down from the peak).
Consider storing your control system alarm panel in a hidden bedroom cupboard or closet area for easy access in an emergency and for peace of mind that it's in a safe space. If you have a wireless keypad, this can make installation in a closet or hidden area much easier.
The standard height for an alarm system keypad is probably around 4.5 feet high.
located at a height of 1.2 to 2.0 metres above the floor level and be securely mounted to a fixed structure or a structure designed for that purpose. supplied by an RCD protected circuit at the switchboard it originates from. provided by a clearly marked 'isolating switch' that controls the incoming supply.
Controls or switches intended to be used by the occupant of the room or area to control lighting and receptacle outlets, appliances, alarms or cooling, heating and ventilating equipment shall be located no more than 48 inches (1219 mm) measured from the top of the outlet box nor less than 15 inches (381 mm) measured ...
Unless otherwise authorized, all normal circuit height are 1000 feet above aerodrome elevation. If you need fly over the airport for example to know which runway in use the height will be 1500 feet above aerodrome elevation.
The centre of the element of the manual call point should be positioned 1.4m (+/-300mm) from floor level. Unless a wheelchair user is likely to be the first person to raise the alarm. (Between 800-1200mm according to Doc.
How high should I mount a sounder/beacon? A standard sounder/strobe or individual strobe should be mounted 2.1m above the floor and not closer than 150mm from the finished ceiling.
You'll often see FACPs placed close to the front entrance for this reason. In larger buildings, they'll be in an enclosed emergency control room - if that's the case, you'll have to install annunciators to ensure occupants can hear the panel's alarm signal.
The repeater is placed between two devices to boost the signal strength and extend the communication range.
It works by receiving the signal outside, amplifying it and rebroadcasting it in an area. It also amplifies the signal from the cell phone and sends it back to the cell tower.
Final answer:
Repeaters are devices that amplify signals in networking but do not relay packets among networks. They only operate at the physical layer and are sometimes called regenerators. Therefore, the incorrect statement is that repeaters relay packets among multiple interconnected networks.
