Model 4734 Access Control Expander Installation Manual (P/N 150807, Rev. A) Revised 5/98

Outputs are generated on three types of devices:
1. Model 4720 panel Terminals 15, 16, and 18: Terminals 15 and 16 are open collector outputs that switch
low when activated (negative voltage; -12 VDC, 50 mA maximum). Terminal 18 switches high when
activated (positive voltage; +12VDC, 20 mA maximum). The following figure shows how each of these
terminals would be connected to an output device.
NOTE The default I/O program sets Terminal 15 as a common FIRE alarm output and Terminal 16 as a common
INTRUSION alarm output.

2. Model 4180 Status Display Module: Two modules can be daisy-chained to provide up to 32 outputs.
Each module has four relays, which can be activated by any of the 16 outputs. The top three sections of
Table 20 (Section 6.5.2 of this manual) show which relay label identifies each output.
3. X-10 compatible modules: The 4734, with the Model 4181 Power Line Interface, can control up to 32
X-10 modules. These modules, which come in many forms, can be used to control lights or appliances.
Table 20 (Section 6.5.2 of this manual) shows the correlation of X-10 label to X-10 module.
EXAMPLE: If one of the 4180 Status Display Module’s relays were connected to an LED, you could
program the system to light the LED if the printer ran out of paper.
You can also program a device to produce an output when a specific combination of conditions exists. This
is done by performing logical operations, as shown in Table 17. (The 5540 software and built-in program-
mer are also capable of using arithmetic operators. These operators are included in Table 18.)
