Figure 6: Two-wire smoke detectors and initiating devices (personality codes 13, 14, 20, 21)
(1) Class A two-wire smoke circuit
(2) Maximum 12.5 Ω resistance per wire for Class A configurations
(3) Class B two-wire smoke circuit
(4) Not allowed with personality codes 14 and 21
(5) UL/ULC Listed 15 kΩ EOLR (PN EOL-15) for Class B only
(6) Smoke detector power (24 VDC) from Signature controller,
SMK, or 2-SMK
(7) Signaling line circuit (SLC) to next device
(8) Signaling line circuit (SLC) from previous device, power-limited
and supervised
(9) UL/ULC Listed 22 kΩ EOLR (PN EOL-22) for Class A only
Figure 7: Class A or B notification appliance circuit (personality codes 15, 16)
(1) Class A notification appliance circuit
(2) Class B notification appliance circuit
(3) Signal polarity shown when the circuit is normal. Polarity
reverses when the circuit is active
(4) Use twisted pair wires for speaker circuits. All other circuit types
use untwisted pair
(5) Supervised and power-limited unless connected to a nonpower-
limited source. If the source is nonpower-limited, eliminate the
power-limited mark and maintain a minimum of 0.25 in.
(6.4 mm) space from power-limited wiring. For other mounting
methods, see enclosure and bracket installation sheets to
maintain separation of power-limited and nonpower-limited
wiring. The wire size must be capable of handling fault current
from nonpower-limited source.
— or —
Use type FPL, FPLR, FPLP, or permitted substitute cables,
provided these power-limited cable conductors extending
beyond the jacket are separated by a minimum of 0.25 in.
(6.4 mm) space or by a nonconductive sleeve or nonconductive
barrier from all other conductors. Refer to the NFPA 70 Nationa
l
Electrical Code for more details.
(6) 47 kΩ EOLR (P/N EOL-47) used for Class B only
(7) Signaling line circuit (SLC) from previous device, power-limited
and supervised
(8) Signaling line circuit (SLC) to next device
(9) Audio riser (from previous device)
(10) Audio riser (to next device)
(11) Power-limited regulated, power supply listed for fire protective
signaling use
(12) Use twisted pair wires for audio riser. All other riser types use
untwisted pair.
(13) If using horns while connected to a compatible fire alarm control
panel that does not produce a temporal pattern, a CDR-3 bell
coder must be used to comply with ANSI S3.41.This module
does not provide signal synchronization.
