Telephone Wiring
For programming, the AM-3 connects to a standard telephone line.
✦ NOTE: The optional Model ACM-1 modem is required for
telephone communications to the AM-3 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 AM-3 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 AM-3’s
PHONE LINE jack and the modular telephone jack wired to the
installation’s telephone line.
PBUS Accessories
Several accessories (keypads, proximity readers, remote receivers)
can be connected to the AM-3’s 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 AM-3 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
1. Mount and install the accessory as described in its installation
instructions.
2. Route 6-conductor cable from the AM-3 to the accessory.
• For wire runs up to 300 feet use 24 AWG Belden Type 9931 or
equivalent.
• For wire runs up to 500 feet use 20 AWG Weico Type 9405 or
equivalent.
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
AM-3.
4. Connect the 6-conductor cable to the accessory and the AM-3.
