It looks very achievable – it looks like a classic
vendor-written specification masked as a biddable open specification. It has
all hallmarks: soaring performance claims alternating with competition-limiting
specificity. From the consumer side, quite frankly, when I read stuff
like that I always feel that the designer is selecting a product without
assuming responsibility for product selection. It often works, but when the
customer detects it, his respect for the designer goes way down.
I suspect you could figure out which vendor wrote it by finding
the description in the sales brochures of the companies listed…

Subject: [bsp-forum] Person Machine Interface (PMI)
Hi
Michelle and Rex,
I'm reviewing a digital addressable fire-alarm system for a hotel. The
paragraph below caught my attention and wanted to pass along to you see if this
is realistic or achievable. It makes me now worried about the Building Control
System requirements too. Typically I only review for conflicts with the
contract and similar but I couldn't help notice this perhaps unachievable
result.
Any expertise or comments would be sincerely appreciated.
Thanks - Deborah
The Person Machine Interface (PMI) or the Remote Person Machine Interface
annunciator (PMI REM) shall provide the system information on six inch 1/4 VGA
monochrome LCD, with Touch Screen and LED display. The PMI shall provide
floor plans with alarm type and "You Are Here" indication. The
PMI shall be navigable by device/module custom message in the system
architecture with no need for device address knowledge. The PMI shall
provide a physical as well as a system graphic view. Graphic user
interface shall be menu driven with 4 tabs showing the level and the total
events for each tab. The tabs shall be; Alarm, Supervisory, Trouble, and
Security. Each level shall show 5 events simultaneously. The LED
displays shall indicate Power, Audibles On or Silenced, and Partial system
disabled. Systems not having the above LEDS shall provide separate LED's
within the control panel enclosure with appropriate labels. Selection
buttons shall be backlit to aid the operator in the selection process.
There shall be controls for scrolling throughout the event list. A
button shall provide zoom in and zoom out for the amount of information desired
for a specific entry. The PMI shall be capable of monitoring the power
supply loading and show available capacity for future expansion planning.
The PMI LCD shall provide standard NFPA symbols showing Fire Service
Equipment, Hazards compliant with NFPA 170 and People in the area of alarm.
Systems without this type of display shall supply a UL listed Graphics
package with their system. The LCD shall have a keyboard screen to allow
the technician ability to enter test and numbers for passwords or text changes.
The module shall be model number PMI.
Acceptable Manufacturers listed are: Seimens Building Technologies (Branch
Office Only); Simplex; Edwards System Technologies Inc.; and Notifier.
