================================================================

This week's installment of ET Journal is the last element review
in Level III. Next week I'll start on the Level IV elements.
There are only 15 elements in Level IV so in oh about 15 weeks
or so I'll run out of material! If you have something in mind for
ET Journal, let me know!

----------------------------------------------------------------

I'll see you in Billings this week.

Have fun!

NICET Fire Alarm Systems Level III
36002 LOW POWER WIRELESS LOCAL SIGNALING SYSTEMS
------------------------------------------------

36002 is a Level III Special Work element.

36002 DESCRIPTION
Understand low power wireless systems. where they are permitted,
and the supervision, power supply, alarm transmission, and
special signaling required for their use. (NFPA 72, Fire Alarm
Signaling Systems)

36002 REFERENCES:
NFPA 72

36002 DESCRIPTION BREAKDOWN:
"Understand low power wireless systems. where they are permitted,
and the supervision, power supply, alarm transmission, and
special signaling required for their use."

The equipment will be specifically listed for the purpose and
equipment solely listed for household use does not comply with
this requirement.

A primary battery (dry cell) is be permitted to be used as the
sole power source provided that:
1. Each transmitter serves only one device and is identified at
the control panel.
2. It will be capable of operating the transmitter for not less
than 1 year before the battery depletion threshold is reached.
3. A battery depletion signal will be transmitted before the
battery has depleted to a level insufficient to support alarm
transmission after 7 additional days of normal operation. The
signal will be distinctive, visibly identify the transmitter,
and if silenced, resound at least once every 4 hours.
4. Catastrophic battery failure will cause a trouble signal
identifying the affected transmitter. If silenced, it will
automatically resound at least once every 4 hours.
5. Failure of a battery in a transmitter will not affect any
other transmitter.

When actuated, each low power radio transmitter will
automatically transmit an alarm transmission at intervals not
exceeding 60 seconds until the initiating device is returned to
normal. Fire alarm signals have priority over all other signals.
The maximum allowable response time is 90 seconds. The alarm
signal will latch at its receiver/control unit until manually
reset and identify the particular initiating device in alarm.

The transmission method will be highly resistant to
misinterpretation and interference. The occurrence of any single
fault that disables transmission will cause a latching trouble
signal within 200 seconds.

A single fault on the signaling channel will not cause an alarm
signal. The normal periodic transmission from a low power
transmitter will provide assurance of successful alarm
transmission capability.

Removal of a transmitter from its location will cause immediate
transmission of a distinctive supervisory signal that indicates
its removal and individually identifies the affected device.

Any unwanted (interfering) transmission received for a continuous
period of 20 seconds or more will cause an audible and visible
trouble indication at the control unit. This indicator will
identify the specific trouble condition present as an interfering
signal.

NFPA 72-1999 3-10.3.2 Each low-power radio transmitter will
automatically repeat alarm transmission at intervals not
exceeding 60 seconds until the initiating device is returned to
its non-alarm condition.

NFPA 72-1999 3-10.4.6 Reception of any unwanted (interfering)
transmission by a retransmission device (repeater) or by the main
receiver/control unit, for a continuous period of 20 seconds or
more, will cause an audible and visible trouble indication at the
main receiver/control unit. This indication will identify the
specific trouble condition as an interfering signal.

NFPA 72-1999 3-10.4.2 The occurrence of any single fault that
disable transmission between any low-power radio transmitter and
the receiver/control unit will cause a latching trouble signal
within 200 seconds.
