14.0 SMOKE DETECTOR OUTPUT
Terminals 30 ( - ) and 31(+) are only for the power connection of 4-wire Model SPB-24 projected beam smoke
detectors. Operation of the reset switch interrupts this output to reset all detectors. See Figure 10.
Voltage
24 VDC (nominal)
Max. ripple voltage
.071 VAC (RMS)
Current
1.75 amp.
Power limited
Unsupervised
Two-wire photoelectric or ionization smoke detectors must not be connected to these terminals. See Section
16.1 on the ZDM.
15.0 ZONE ALARM DRY CONTACTS
A set of Form “C” dry contacts rated 2 amps at 24
VDC (resistive), are provided for each zone when
a ZDM or VZM is installed. They are intended for
connection to circuits powered from a Listed power
limited source of supply. Terminal 35 is common,
34 is normally open, and 33 is normally closed. See
Figure 11. These contacts transfer only when there is
an alarm on that individual zone, and they will remain
in the alarm condition until the control is reset. The
position of the zone maintenance switch WILL NOT
AFFECT THESE CONTACTS. Jumpers in the matrix
are not required to operate these contacts.
16.0 INITIATING CIRCUITS
16.1 Zone Detector Module (ZDM)
Terminals 37 through 40 are provided for each zone, and will accept U.L. Listed normally open initiating
devices such as heat detectors, thermostats, and manual stations. See Figures 12 and 13.
FCI approved, U.L. Listed compatible, two-wire photoelectric and ionization smoke detectors that use the
supervisory current from the initiating circuit as their power source can be used. Each zone is capable of
powering a specified number of FCI approved detectors. See FCI Addendum, P/N 9000-0427 for a list of
approved detectors.
One ZDM is required for each active zone and will accept either Class A, Style D or Class B, Style B 4-wire
or 2-wire circuits. Each zone module has an individual maintenance switch as well as a supervised red
“ALARM” LED and a yellow “TROUBLE” LED.
