Westin SFO Get Fire Alarm Upgrade

Notifier Onyx Series EVAC Upgrade for Westin SFO

Pyro-Comm Systems, a NESCO affiliate for Notifier just completed a rather complex fire alarm upgrade as it was for an occupied 7 story hotel in the San Francisco area.  The old Simplex 4100 was replaced with a much needed upgrade.  We installed a new Notifier NFS2-3030 with 7 SLC loop cards, full voice, fire phones and all new System Sensor speaker strobe devices.  Here are some pictures of the fire control room before paint.  Sorry for the split pictures as the room is to small to get the shot all in one.

The cabinet in the upper center is full of 5 Notifier XP6-C addressable control module cards to control the fire phones, first floor fire alarm speakers as well as the 5 elevator cabs and 4 stairwell fire alarm speaker circuits.  Below that cabinet are two battery cabinets each with 2 55aH backup batteries.  One for the Notifier NFS2-3030 and the other for the amplifier cabinet located to the right.  The amplifier cabinet is filled with 4 100 watt amps to power up the 7 floors.  Finally to the right of the amp cabinet is three new 12 amp Honeywell remote power supplies used for both the first floor strobe circuits as well as 40 door holders.

Also not shown in the pictures are the two LCD-160 remote annuciators, the fire phone jack handset storage cabinet and one system printer.  All in all it came out really clean. 

We will be writing another post soon with the details of the installation as we ran into some time consuming obstacles

Fire Alarm Speaker Zone with Music

Testing Emergency Voice/Alarm Communication speakers with Music 

Here is a great idea when installing voice evacuation systems.  Install an addressable relay and control module for each fire alarm Emergency Voice/Alarm Communication  speaker zone.  Once installed map the addressable relay such as an FRM-1 to a function button such as the DVC with Notifier.  This can all be done through the display and or laptop computer.  Make sure to label the DVC (Digital Voice Command) button with the area served by the speaker zone as well as music such as "Stair #1 MUSIC".  Once you select the Notifier DVC button it will activate the addressable relay.  Hook up an addressable monitor module such as the MMF-101 for Notifier to the SLC and the class B zone leads to the normally open contacts on the addressable relay (FRM-1).  This monitor module should be programmed to activate the music in your program for that specific speaker zone.

Did I lose you yet?

Step #1:  Map a system function button to an addressable relay
Step #2:  Connect the addressable relay to an addressable monitor module (N.O.)
Step #3:  Program the addressable monitor module to activate a specific speaker zone
Outcome:  When you push the button it activates the relay, the relay shorts out the monitor module and activates the music from your program onto that specific speaker zone.

What is the reason for this?

Every time you perform your emergency voice/alarm communication system testing you can do a quick functional test of the speaker zone paging and alert messages to verify voice intelligibility and sound pressure levels.  After these levels have been verified, you can select the music function and play soft music through the speakers while you walk around and verify audibility/functionality throughout the facility.

Pretty slick right?

Just make sure to have the program written to activate a system trouble at the fire control panel every time this function is in use.  This will ensure that you do not leave a site with music in place of the actual alert tone.
