4.1 Mounting the D1256 and D1257
The D1256 and D1257 are low profile, surface-mounted units molded in durable red plastic. They can be mounted using
the following optional packages:
•
D56 Command Center Keypad Conduit Box (protected surface or flush mount)
•
D54B Command Center Flushmount Kit (brass)
•
D54C Command Center Flushmount Kit (stainless steel)
4.1.1 Mounting Locations
Do not mount annunciators in a location where they are exposed to direct sunlight. Direct sunlight can interfere with the
display screen's visibility and damage internal components. Do not mount the annunciators in wet or moist locations.
4.2 Wiring the D1256 and D1257
A four-wire flying lead (see Wiring harness connector in Figure 1) is required for the data and power connections between
the annunciators and the control panel. The annunciators come with a wiring harness consisting of four color-coded
flying leads with a female four-pin connector plug at one end.
To wire the D1256 and D1257:
1. Power down the control panel.
2. Connect the flying leads of the wiring harness (provided) to the wiring terminals on the panel.

enclosure base.
5. Mount the annunciator's base to the wall. Secure it in place using the three mounting holes inside the
enclosure base.
6. Replace the cover. Align and insert the top two tabs of the enclosure cover into the top two tab slots of the
enclosure base.
