NOTES
1. Power limited to
NFPA 70 per NEC 760.
2. Minimum wire size:
18 AWG.
3. Maximum resistance:
70 ohms total
(40 ohms if relay
bases are used).
4. Each detector or group
of detectors, requires a
two-wire circuit of
thermoplastic fixture
wire enclosed in
conduit or limited
energy shielded cable
without conduit, if
permitted by local
building codes.
5. Loops may be wired
Class A (Style D) or
Class B (Style B).
6. 30 devices maximum
per loop.
7. All circuits are
supervised.
8. Do not connect more
than one PBA-1191 to
each zone. (Refer to
PBA-1191 instruction,
P/N 315-095424 for
further information.)
9. Do not mix smoke
detectors with the
PBA-1191.
10. The PBA-1191
requires Rev. 3 or
higher of CZM-4
firmware.
Initiating devices per zone:
Up to 30 detectors, any combination of
those listed in Appendix A, Table 1 -
Conventional Detectors (except the
PBA-1191), on page A-1, may be used.
