SPECIAL OPTIONS
1)
PANIC ALARM:
This option provides a means by which the alarm will annunciate when
personnel are inadvertently locked in a compartment. When so ordered, a twisted pair of wires is
attached to the alarm for activation of this feature. Wires are connected to a Toggle or Push Button
Switch (Not Provided) which is installed in a waterproof enclosure inside of the compartment.
Activation of this switch causes the alarm to annunciate.
2)
DOOR AJAR:
This option provides a means by which the alarm will annunciate when a
compartment door is left open for longer than 10 minutes. (Other times available.) A yellow
“DOOR AJAR” light will glow and the alarm will begin to “time out” every time the door is open.
If the door is open beyond 10 minutes the alarm will annunciate. Closing the door will reset the
alarm unless a Temperature Alarm is occurring simultaneously. A twisted pair of wires is attached
to the alarm for activation of this feature. Wires must be connected to a switch (not provided) that
will provide a contact closure whenever the door is open.
3) 75MP: The 75MP is a 2, 3 or 4 probe version of the Model 75 for the monitoring of large
rooms or smaller temperature sensitive rooms. Alarm scans and displays probe temperatures at
four second intervals. Otherwise, operation is identical to a standard alarm.
SAMPLE SPECIFICATION: MODEL 75 & 75B
MODEL 75:
Each refrigerated compartment shall be monitored by a MODULARM MODEL 75
TEMPERATURE ALARM (Surface or Flush Mount.) The alarm shall provide a constant digital
readout of monitored temperature, field adjustable high & low alarm temperature set-points and
field adjustable time delay to override normal rises in compartment temperature. Two visual status
indicators are provided: a green “Safe” light and a red “Alarm” light. Under normal conditions
the green “Safe” light and a red “Alarm” light. Under normal temperatures the green light is on
and the red light is off. Abnormal temperatures cause the green light to extinguish and the red
light to blink. Abnormal temperatures exceeding the time delay cause a constantly on red light,
activation of the horn for audible annunciation and activation of the self- contained relay for
remote notification. The unit shall be reset manually with the Alarm Control Switch. Fail safe
circuitry shall prevent accidental disabling of the unit. The alarm shall be enclosed in a drawn
aluminum enclosure with a stainless steel faceplate.
75B ADDENDUM: When power failure occurs the green light will extinguish and the red light
will begin to blink. Simultaneously, the horn will beep on and off and the internal relay will
activate for remote notification.
