Telephone Wiring
For programming, the AM3Plus connects to a standard telephone line.
✦ NOTE: The optional Model ACM-1 modem is required for
telephone communications to the AM3Plus controller.
Important Telephone Wiring Tips
• DO NOT ROUTE TELEPHONE AND AC WIRING INSIDE THE
SAME CONDUIT. Route all telephone wires inside a dedicated
conduit that is at least six inches away from any AC line wiring.
• All telephone wiring must be made on the “building” side of the
telephone company’s demarcation device (the terminal block
where the telephone line connects to the building).
• If any security system or personal alert system at the installation is
connected to the telephone line, be sure that it is connected to the
line ahead of the AM3Plus using a RJ-31X interface.
• Use only high-quality telephone wire. All telephone wire should be
twisted-pair with a minimum size of 24 AWG.
Typical Telephone Wiring
1. Connect a double-ended modular cable between the AM3Plus’s
PHONE LINE jack and the modular telephone jack wired to the
installation’s telephone line.
PBUS Accessories
Up to six accessories (keypads, proximity readers, remote receivers) can
be connected to the two PBUS input/output ports. A typical application for
a remote keypad would be to control a second door or gate.
Linear’s PBUS devices compatible with the AM3Plus are:
• AM-RRR Remote Radio Receiver
• AM-RGR Remote Radio Receiver
• AM-RPR Radio Proximity Receiver
• AM-KP Exterior Keypad
• AM-KPI Interior Keypad
• AM-CRI Card Reader Interface
Conventional cable or commonly available Cat-5e Ethernet cable can
be used to connect PBUS remote devices to the AM3Plus. When using
Cat-5e cable, note that the PWR and GND connections use two wires
each to enhance the current carrying capacity for powering the remote
device.
Cable choices:
• Cat-5e Ethernet cable for wire runs up to 500'.
• 24 AWG Belden Type 9931 or equivalent for wire runs up to 300'.
• 20 AWG Weico Type 9405 or equivalent for wire runs up to 600'.
1. Mount and install the accessory as described in its instructions.
2. Route cable from the AM3Plus to the accessory.
3. Set the DEVICE ADDRESS rotary switch in the accessory to
a unique address number. When programming the system, the
device address number will identify each PBUS accessory to the
AM3Plus.
4. Connect the cable to the accessory and the AM3Plus (see PBUS
wiring diagram).
