MTA CAMS PRDC Fire Detection and alarm system Signals (Dedicated function system) Flashcards
What type of fire alarm system is required for signal FA systems ?
an addressable FA system
What are some areas that will be included in this FA system ?
relay rooms
central instrument rooms
and train controls
what must occur during the change in fire alarm systems?
fire watch must occur
What is a another option that the design–builder can consider doing besides replacing the Signal FA system ?
Alternatively, the Design-Builder may elect to utilize the existing signals fire alarm system provided that it can be expanded to meet the requirements of this section without resulting in an impairment to existing signals areas that must be protected during construction
For new signals areas located within the stations under the Contract what should be done ?
connect the new signals fire alarm system to the existing station FACP for monitoring at the agent booth location
What are some actions required to be done on new signals areas
upgrade, replacement, programming and testing
if the signal FA system is not able to connect to the main FACP what should be done
a remote annunciator should placed in the agent booth that is connected to the signal FA system
What must be done in order to have a remote annunciator for a signal FA system in place of connecting it to the main FACP
request document must be sent to the project CEO outlining that that the alarm system is not able to be expanded
Where will normally occupied stand alone signals buildings have their remote annunciators installed if they are required
in the maintenance supervisor office
If a signals area is located within a station that is already controlled by a full station alarm system what must occur when implementing the station alarm system
The existing Fire alarm system notification devices will be extended into the signal areas effected
What will happen if their is a fire in the signals area that has notification devices connect to a existing full station alarm system that also has a signal alarm system
the alert the notification devices will only the existing full station alarm system and not the signal alarm system
What will happen in the event that an alarm occurrence is activated in the the signal alarm system and how will this action be done
An activation of the signal alarm system shall not result in the activation of the station fire alarm appliances
this will be done using signal modules on a room by room basis
Were should the fire alarm panels for signals be placed
either in the fire suppression room for releasing systems or in the relay room if installations do not include clean agent protection.
What is the only thing that the FA panels for the signal room should protect
it should only protect signal related rooms
What is a clean agent ?
A clean agent is a fire extinguishing agent that is volatile, gaseous, or electrically non-conductive. It does not leave a residue when it evaporates.
