8701 Module
The 8701 contact monitoring module interfaces direct shorting devices to the
System’s Addressable Device Circuit.
The 8701 can monitor a normally open or closed dry contact and it can report
the status of the contact.
PROGRAMMING
Refer to Figure 1 to locate the red and black Addressable Device Circuit
wires of the 8701.
Connect the Addressable Device Circuit wires of the 8701 to the Model
8720 Programmer/Tester. Use the cable provided with the Programmer/
Tester and the two alligator clip to banana plug adapters provided.
To Prevent Damage To The 8720:
DO NOT connect an 8701 to the 8720 until all field wiring is removed from the red and black ad-
dressable device circuit wires of the 8701.
NOTE: Connection from the 8720 to the 8701 is not polarity sensitive. Refer to Figure 2 for the
proper connections to the control panel.
Follow the instructions in the 8720 Programmer/Tester Manual (P/N 315-033260FA) to program the
desired address into 8701.
Record the device address on the label located on the 8701. The 8701 can now be installed and wired to
the system.
WIRING
(Refer to Figure 2.) Refer to the wiring diagram and wire the addressable interface module accordingly.
NOTE: Recommended wire size: 18 AWG minimum, 14 AWG maximum

Installing the 8701 Wiring
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. 8701 is polarity insensitive. Line 1 and Line 2 can be either line of the loop.
4. The supervised switches have the following ratings:
Voltage maximum: 27 VDC
Current maximum: 6mA during polling
Contact resistance maximum: 10 ohms
Maximum cable length: 200 feet (18 AWG) CLine to line: 0.02uF CLine to shield: 0.04uF
Max line size: 14 AWG Min line size: 18 AWG
CAUTION: Ground shield ONLY at the specified location on the Control Panel.
CAUTION: EOL device must be a 470 ohm, 1/4W resistor. When replacing an existing 8701 on a device loop, you must also replace
the EOL resistor if it is not 470 ohms, 1/4W.
5. The green wire 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 green wire.
b. Use shielded wire to connect the switch wiring.
c. Tie the switch wiring shield to earth ground.
6. The 8701 draws 1.3mA from the addressable device circuit.
7. All circuits are power limited.
Mounting
The 8701 mounts directly into a single gang switchbox (user supplied)
Connect the appropriate wires using wire nuts.Tuck the 8701 module inside the electrical box and dress
the wiring as required. (See Figure 3.)
