DETECTOR USE IN HAZARDOUS
AREAS

The Dual Spectrum® Models PM-5MP and PM-5MP+ are
Factory Mutual Approved to 3260, 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 suit-
able 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 A) for installation instructions
and component selection criteria.

ELECTRICAL CHARACTERISTICS

The PM-5MP and PM-5MP+ are designed to interface to
any NFPA type fire alarm control panel. A normally open
contact is provided for an alarm signal. The alarm con-
tacts 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
B to D), 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 normal operation with no faults.

OPERATING VOLTAGE—
9 to 30 VDC at the detector (observe polarity), including
line drops and ripple.

NOTE

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.

WIRING HARNESS—
Identification:

See Table 1.

Length:

50 feet (15 m).

Diameter:

0.3 inches (7.6 mm).

Individual Wires: 20 AWG, solid.
