Note: When zone 3 is programmed to accept 2-wire smoke detectors, it
will only function as a NFPA Style-B initiating device circuit. See
figure 3.2-1.
Zone four is a Style B circuit designed as a Supervisory zone or may
accept any N.O. contact device on TB2, terminals 9-10. As a
Supervisory zone, the circuit may or may not be able to detect a
supervisory alarm condition after the occurrence of an open in the loop
wiring. It's power limited to 2.66 mA in Standby and 4.46 mA in alarm.
Factory Default is "Supervisory." Refer to Section 4.0 Programming.
Zone five is a Style B Initiating Device Circuit designed as a general
purpose "initiating zone." It will accept any N.O. contact device on
TB2, terminals 11-12. It's power limited to 2.66 mA in Standby and
4.46 mA in alarm. Factory Default is "4-wire Smoke Detector." Refer to
Section 4.0 Programming.
Four wire smoke detectors may be connected to any zone. Resettable
power is provided via terminals TB2, 13 and 14. See Figure 3.2-1 for
proper connection of 4-wire detectors..
It is allowable to mix an assortment of device types on any zone,
however it is not recommended. By not mixing device types on any zone,
messages sent to the Central Station may be very specific and detailed.
