Initiating Device Circuits 1 or 2 on TB4 can
be used with either Style B (Class B) or
Style D (Class A) wiring.
A maximum of 200mA is available from
the +24VDC four-wire smoke detector
power circuit on TB1 terminals 3 and 4.
Any power that is drawn from the +24VDC
Nonresettable Power on TB2 terminals 1
and 2 must be subtracted from available
four-wire detector power. (See “Specifica-
tions” in Section 1.6 and “Powering
External Devices” in Section 2.7.)
Refer to the Device Compatibility Docu-
ment for suitable four-wire smoke
detectors.
Notes on Style D (Class A) and Style B
(Class B) field wiring:
1. The Power Supervision Relay coil
leads must be connected to the last
detector base 24V screw terminals.
2. Calculation of the maximum allow-
able resistance in the 24VDC
detector power wiring:
R
MAX
= (2 0 .6 - V

Where:
R
MAX
is the maximum resistance of the 24V
wires.
V
OM
is the minimum operating voltage of
the detector or end-of-line relay,
whichever is greater, in volts.
N
is the total number of detectors on the
24V supply loop.
I
S
is the detector current standby.
N
A
is the number of detectors on the 24V
power loop which must function at
the same time in alarm.
I
A
is the detector current in alarm.
I
R
is the end-of-line relay current.
