MOUNTING THE ENCLOSURE
(For indoor use only in dry environments)
The fire alarm control unit must be mounted in a properly accessible location as required by
applicable codes. Any auxiliary battery box or other accessory not connected through a
protective device or a circuit designed for remote connection must be within the same room
and connected through electrical conduit. Installation is to be done only by qualified
personnel who have thoroughly read and understood these instructions.
When mounting the enclosure on interior walls, use appropriate screw anchors in plaster.
When mounting on concrete, especially when moisture is expected, first attach a piece of
¾-inch plywood to the concrete surface. Attach the PAD-5 enclosure to the plywood.
Consult the installation instructions included with the enclosure for proper mounting.
When two (2) PAD-5-MBs are mounted in the same enclosure, it is customary to share the
1 battery set between the 2 PAD-5-MB. In this case, one of the PAD-5-MB must have its
battery charger disabled. Refer to the Zeus programming tool to disable the charger.
Disabling the charger can only be done this way.
NOTE
→
If using both types of power supplies, FP2011-U1 and FP2012-U1, in the same enclosure,
then disable the PAD-5-MB battery charger that is connected to the smaller power supply.
If both power supplies are the same, then it does not matter which PAD-5-MB has its
charger disabled.
2.1 Mounting the Boards
Installing the PAD-5-MB to the Enclosure (See Figure 2)
1. The enclosure is installed in its proper place.
2. The knockout locations for passing through cables have been removed.
3. Install the power supply. The size of the power supply is determined by the battery
calculation spreadsheet, (See Section 3.4). Use the four (4) #10/32 nuts provided
in the power supply package. Refer to the power supplies installation sheet for
additional information. See Figure 3 for details.
4. Install the Adapter Plate with the PAD-5 Main Board on the four (4) #10-32 studs of
the enclosure and use the 10-32 hex nuts that are provided to secure the adapter in
place.
5. Run AC through the left side knockout. See Section 2.3. Connect the wires as
shown in Section 3.1 (Figure 6). Tie Earth to the Ground Lug located near the
power supply. Do not connect the power supply to the PAD-5-MB until all
configuration jumpers are set, and any option module (if installed) is mounted and
secured.
6. Wire all terminal blocks according to the following sections for the P2, NAC, NAC
Follower, and Aux. Do not connect power until all field wiring is complete. Use the
knock out drawing in Section 2.3 (Figure 5) for Wire Routing.
7. If no expansion module is being used, make sure the factory installed daughter
bypass card is plugged into X901. If it is not, P2 communication troubles will be
annunciated at the FACP. Also, the daughter bypass card has polarity, so pay
attention to the markings on the module, for proper placement in case the card
is taken out.
8. Before applying power, the address needs to be set on the PAD-5-MB (and the
expansion card if using one). Do not have the expansion module connected to the
