The MIC-M noise sensor is an alarm enhancement device that does
not require direct connection to a monitored piece of equipment.
In operation this unit continuously "listens" for an audible alarm
to be sounded. When it "hears" an alarm it sends an output the host
DPX-M and the adjustable time delay sequence is started. This audible
sensing provides the ability to extend alarms from devices that do
not provide their own auxiliary outputs.
The DPX-M alarm time delay controller is a low cost device for
extending and enhancing the alarm outputs of any device that emits a
loud audible alarm. Direct connection from nurse call output cables
is possible with the addition of our ADP-1 nurse call adapter.
The unit has an adjustable "on delay" timer to absorb
repetitive nuisance alarms, the greatest cause of Alarm Fatigue. To enhance and extend audible alarms the DPX-M
provides two "MIC/IN" jacks for connection to our model MIC-M noise
sensor. The MIC-M is mounted within two inches of the audible alarm
on the monitored equipment. The MIC-M "hears" when an alarm is
sounded and then sends an input to the DPX-M. If this input is
present for a period greater than the delay time the DPX-M provides
two outputs. The jack labeled "OUT" supplies a normally open relay contact for
interfacing to external Nurse Call systems. The jack labeled
"REMOTE" provides 20 volts D.C. to power our model PZ-M remote
buzzer.
The PZ-M is a low cost remote buzzer for extending audible alarms
into the corridor or to a central location. The device emits a loud
continuous or pulsing tone (internally set) and has a 24 volt lamp
to indicate alarm status.
The PZ-M is powered by a host DPX-M time delay controller and is
connected with plug ended cables. It is light enough (4 oz.) to be
"3M Dual Lock™'d" to a ceiling grid, door frame, corridor light or
wall.
When used in combination with a MIC-M noise sensor , DPX-M time
delay controller, and 40' cable , a portable alarm extension and
enhancement system can be utilized.
The DPX-I in line time delay is a low
cost device for enhancing remote alarms by allowing intermittent
nuisance alarms to be absorbed or filtered out.
When an external device alarms, the DPX-I
starts counting down. When the adjustable time period is reached the
DPX-I activates the Nurse Call system at the headwall and will
continue to do so until the external system is reset. This delay
feature will keep staff from becoming immune to constant false and
nuisance alarms.
The ADP-1 Nurse Call Adapter allows an external system to plug
directly into the DPX-M time delay controller's inputs.
Typically a normally open nurse call output cable is plugged into
the ADP-1, the modular cable is plugged into the host DPX-M mic/in
jack. When an alarm condition starts the DPX-M will delay the
transmission of the alarm for an adjustable 0-30 second period. A
dummy plug is provided silence the cord removal alarm feature.
The NC-1 along with a PZ-M lamp / buzzer, XFORM-1 power supply and MOD-CA-40 (40' cable) provide a low cost stand alone direct connect remote alarm system. The NC-1 accepts a normally open 1/4" nurse call type plug.
The NC-2 along with a PZ-M lamp / buzzer, XFORM-1 power supply and MOD-CA-40 (40' cable) provide a low cost stand alone direct connect remote alarm system. The NC-2 accepts a normally open 1/4" nurse call type plug. Installing a 9 volt battery in the NC-2 allows the system to alarm continuously if wall power is lost or a disconnect occurs.
The ANN-5 lamp panel provides a central audiovisual monitoring point for our corridor mounted PZ-M remote lamp-buzzers. The PZ-M remote buzzer includes two modular jacks, one that connects to the room at the DPX-M, NC-1 or NC-2 and one for connection to the ANN-5.
