Honeywell 3.5 Installing the Keypads, Installing the Control, Step Action, Wire Gauge, Length

Installing the Keypads

•Up to 31 addressable keypads (addresses 00-30) may be used (you may need to use an auxiliary power supply if the 750mA aux. output is exceeded). The following keypads may be used:

•2-line alpha display, 6139/6160

•The length of all wire runs combined, regardless of the wire gauge, must not exceed 2000 feet when unshielded quad conductor cable is used (1000 feet if unshielded cable is run in conduit, which acts a shield, or if shielded cable is used).

•If more than one keypad is wired to one run, then the above maximum lengths must be divided by the number of keypads on the run (e.g., the maximum length is 225 feet if two keypads are wired on a #22 gauge run).

To wire the keypads, perform the following steps:

Step Action

1Determine wire gauge by referring to the Wire Run Length/Gauge table below.

Wire Run Length/Gauge Table

Wire Gauge	Length
#22 gauge	450 feet
#20 gauge	700 feet
#18 gauge	1100 feet
#16 gauge	1750 feet

2Wire keypads to a single wire run or connect individual keypads to separate wire runs. The maximum wire run length from the control to a keypad, which is homerun back to the control must not exceed the lengths listed in the table.

3Run field wiring from the control to the keypads (using standard 4-conductor cable of the wire gauge determined in step 1).

4Connect the keypad(s) to terminals 6, 7, 8, and 9 on the control board, as shown in Figure 3-4.

Addressing the Keypads

The keypads will not operate until they are physically addressed and enabled in the system’s Device Programming in the #93 Menu Mode.

Set each keypad for an individual address (00-15) according to the keypad’s instructions. Set an alpha keypad for address 00 and other keypads for higher addresses. Any keypads set for address 02 and above will appear blank until they are enabled in the system’s program. Each keypad must be set for a different address.

•Do not set any keypads to address 31 (nonaddressable mode). They will interfere with other keypads (as well as other devices) connected to the keypad terminals.

•If an “OC” or “OPEN CIRCUIT” message is present on a keypad, data from the control is not reaching the keypad. Please check your wiring.

Supplementary Power Supply for Additional Keypads

When the control’s auxiliary power load for all devices exceeds 750mA, you can power additional keypads from a regulated 12VDC power supply (e.g., AD12612 (1.2A)). Use a UL Listed, battery-backed supply for UL installations.

Connect the additional keypads as shown in Figure 3-5, using the keypad wire colors shown. Be sure to observe the current ratings for the power supply used.

•Make connections directly to the screw terminals as shown in Figure 3-5. Make no connection to the keypad blue wire (if present).

•Be sure to connect the negative (–) terminal on the power supply unit to terminal 7 (–) on the control.
