P/N 315-049475FA-5 PAGE 4 OF 4
NOTES:
1. All supervised switches
must be held closed and/or
open for at least a quarter of
a second to guarantee
detection.
2. End of line device: 470 ohm,
1/4W resistor, P/N 140-
820164.
3. Module is polarity insensi-
tive. Line 1 and Line 2 can
be either line of the loop.
4. 8702/8703/8704 draws
1.3mA from the addressable
device circuit.
5. Supervised switch ratings:
Style B, Class B, See
NFPA72 standard for the
number of normally open
contact devices allowed.
Voltage maximum: 27 VDC
Current maximum: 6mA
during polling
Contact resistance
maximum:
10 ohms
Maximum cable length:
200 feet (18 AWG)
C
Line to line
: 0.02uF
C
Line to shield
: 0.04uF
Max line size: 14 AWG
Min line size: 18 AWG
6. Relay contact ratings:
4A, 125 VAC
resistive
4A, 30 VDC resistive
Inductive:
3.5A, 120 VAC (0.6 P.F.)
3.0A, 30 VDC (0.6 P.F.)
2.0A, 120 VAC (0.4 P.F.)
2.0A, 120 VAC (0.35
P.F.)
2.0A, 30 VDC (0.35 P.F.)
The relay is shown in
standby condition.
7. Terminal 5 must be
connected to earth ground.
a. Use wire nuts to pass the
shield wire through the
electrical box with NO
connection to the device
terminal block or to local
ground.
b. Use shielded wire to
connect the switch wiring.
c. Tie the switch wiring shield
to terminal 5 or the local
earth ground.
