13. What kind of cipher lock and quantities are required e.g. X-10 There is no cipher locks required for the fire alarm. The fire alarm devices, and control panels all need to be keyed to Key 17021.

14. When heat sensors are removed from ceilings what are you looking for as it regards to patching? Acoustical ceiling tiles can be replaced with new tiles but for hard ceilings is it fill in the whole and touch up paint? For hard ceilings fill in the hole and touch up paint.

15. On all touch up paint, is it only at the patch location or do we have to paint from corner to corner? It is only at the patch location. Match paint with current paint. Do not paint from corner to corner.

16. There are a couple of rooms that have a popcorn texture, do we have to also provide popcorn texture for the patches at those locations? Yes

17. There are quite a few acoustical ceiling tiles that are either water damaged or broken, do we need to figure to replace those tiles along with the ones where the heat sensor is being removed? Please do. Must be included in quote.

18. To the best of your knowledge is there any asbestos in the popcorn texture ceilings?

No

19. Section 3.2.1 of "PWS Updated" states "Only sprinklers are needed". Since this is a fire alarm project, shall we ignore this reference to sprinklers? Please confirm that the building is protected by an existing fire sprinkler system. Yes, the building is protected by an existing sprinkler system. It should’ve stated only smoke detectors are needed. No heat detectors are needed.

20. There are scores of references to UFGS 28 31 60, which is the specification for

"Interior Fire Alarm System, Non-Addressable". Please confirm that the appropriate specification is actually UFGS 28 310 70, Interior Fire Alarm System, Addressable".

The correct specification is UFGS 28 31 70

21. Will re-using the existing Monaco Transceiver be allowed? Is it in operational condition? Yes, please re-use the existing Monaco Transceiver. When last checked, it was operational.

22. If re-using the existing Monaco Transceiver is allowed and is found later to be non-operational, will a mod for additional costs to replace be made? No modification for transceiver.

23. If re-using the existing Monaco, will it have to be relocated to a conditioned space.

Please refer to UFC.

24. Will the new Fire Alarm Control Panel be required to mount in same location as the existing faulty control panel next to the existing Monaco Transceiver or moved to an interior conditioned space per the UFC? Please reference the UFC. If UFC says move to an interior conditioned space, please do so.
