DETECTOR USE
AREAS
®
The Dual Spectrum Model PM-5MPX is FM Approved to
FM 3260: 2000, intrinsically safe for use in Class I, II, III,
Division 1, Groups C, D, E, F & G hazardous (classified)
locations; non-incendive for use in Class I, Division 2
Groups A, B, C & D locations and suitable for use in
Class II/III Division 2, Groups F & G. This Approval
depends on proper installation and choice of components,
which are described in this installation manual. See the
following sections and Control Drawing Configuration
(Appendix B) for installation instructions and component
selection criteria.

ELECTRICAL CHARACTERISTICS

The PM-5MPX is designed to interface to any NFPA type
fire alarm control panel. A normally open contact is
provided for an alarm signal. The alarm contacts close
for a minimum of five and a maximum of 15 seconds
when a fire is detected and are automatically reset after
a fire. An internal supervision contact closes when the
detector powers up and opens if a detector fault (such as
loss of power or low power supply voltage) occurs. In
NFPA 72, Class A or B circuits (see Appendix C, D and
E), such a fault condition is indicated at the control panel
as a trouble signal. A blinking red LED on the front of the
housing indicates the following:
1 Hz rate = Normal operation
3-4 Hz rate = Alarm condition.

OPERATING vOlTAGE—
9 to 30 Vdc at the detector (observe polarity), including
line drops and ripple.
Detector output is not guaranteed below 9 Vdc.
The status LED and relay will reflect this condition.
POWER CONSUMPTION—
10 milliamps maximum at +30 Vdc.
AlARM OUTPUT—
Alarm relay is non-latching. Contacts close for 5 to 15
seconds.
TROUblE OUTPUT—
Opening of normally closed relay contacts.
RElAy CONTACT RATINGS—
100 milliamps at 30 Vdc
STAbIlIzATION TIME—
Maximum 0.5 second after power up.
RESPONSE TIME—
1 second maximum.
