Pro-Tech’s Proven Z 28 is now the
Z 28D
Pro-Tech
has been making the eight zone Z 28 alarm since March 1990.
We were forced to make it because Moose Products stopped making the MPI
50, which we used in the MARK XX alarm. Jim’s
favorite saying is “Everything works out for the best” and this has been
true with the Z 28. The first design
had eight outputs for the dialer and nobody used it, so in 1994 we did a redesign
with only one output. Guess what???
Later on some customers wanted the eight outputs so the monitoring
company, Security Central, could tell him or her where to find the problem.
Now we have designed the totally digital Z 28D with a display,
eight
dialer outputs, and no lights. Now
when you receive a call from Security Central if you are using two of the DD3-PTI dialers they can tell you where to find the problem.
The Z 28D
will do all the Z 28 did plus lots more.
Management needs lots of information to make good decisions on large
poultry farms or other confinement buildings and the Z 28D can help.
The Z 28D is an information center, which can monitor up to eight
locations and each location can have multiple sensors.
Information from sensors such as power outages, temperature too high or
too low, and static pressure and low water pressure can be reported to the Z
28D.
When a
problem occurs, the display shows you which zone(s) is violated.
The zone cannot be re-armed until the problem has been corrected.
You can deselect that zone until your problem is corrected so the siren
will stop.
When
the Z 28D detects a problem, it can sound a siren, turn on a strobe
light, and operate a telephone dialer. The
siren has two levels. As long as the
problem exists, the siren produces its maximum sound.
When the problem is corrected, the siren's sound is reduced to one-eighth
its maximum sound. This allows the
manager to know the urgency of the problem.
If the siren is sounding at high level, attention to the problem is
urgent. On the other hand, if the
siren is sounding at low level, it says a problem has occurred, but it doesn't
exist now. Three different sirens
are available for the Z 28D but we recommend using the S 2300 that has a
wider dispersion.
The Z 28D is equipped with a built in battery charger and 12-volt
lead acid rechargeable battery to operate the system in the absence of power.
A test button on the Z 28D activates the alarm and tests the
battery and siren. A switch on the front panel allows the operator to choose
instant response or delayed response. Delayed
response is used when normal operation monitoring is done.
It is best to test the alarm on instant.
No waiting is necessary to test each detection point such as power outage
or temperature.
OPTIONS FOR THE Z 28D
TherMinder
Digital High and Low temperature sensor with Memory.
It has adjustable high and low set points.
It has Normally Open (NO) or Normally Closed
(NC) contacts. This unit
works off of a 9-volt battery or the TherMinder-2L works off of a 12-volt
DC supply from the alarm.
PTI 200 High and
Low temperature sensor. It has
adjustable set points for both high and low temperature limits.
A needle indicates the present temperature.
When this needle touches one of the upper and lower limits the Z 28D
senses the contact.
AIR GENIE The
Air Genie monitors static pressure. There is a threshold set-point that must be
met within the timer period. The timer is adjustable between 3.5 and 22 minutes.
PFD 100-250
100 to 250 Volt AC power outage detector.
(NC) or (NO) contacts.
PFD 415 Three
Phase Power Outage Detector. (NC) or
(NO) contacts
SIREN
Three different sirens are available with 2 levels of sound, high and
low.
1.
The ELK SS15 is an 8-watt self-contained siren rated at 106 db at 10
feet.
2.
The ELK SS30 is a 30-watt self-contained siren rated at 112 db at 10
feet.
3. The S 2300 siren is
a 40-watt wide dispersion and is rated at 114 db at 10 feet.
This is the
one Pro-Tech recommends for the Z 28D alarm.
The MPI 11 siren
NOTE: If
these 3 are not loud enough, a JDS 100 is available.
It is rated at 125 db at 10 feet, the loudest allowed by law, not on an
emergency vehicle.
20P 30
Adjustable Low Water Pressure Detector-It has settings between 0 and 30 psi.
