Connect the black (-) wire from the previous station to the terminal that is connected to the black (-) wire from the addressable module.
Connect the black (-) wire leading the next station to the other side of the terminal that is connected to the black (-) wire from the addressable module
Note: The wires must be on opposite sides of the set screw. Refer to Figure 2 for the location of the wires.
Tighten the (-) terminal.
Connect the red (+) wire from the previous station to the terminal that is connected to the red (+) wire from the addressable module.
Connect the red (+) wire leading to the next station to the other side of the terminal that is connected to the red (+) wire from the addressable module.

Setting the addressable module

Note: MS-402AP: Pull the module out of the bracket to set the address

The AP addressable module allows for an address range of 1 to 159. The TENS dial goes to 15 (unlike the CLIP module, where the TENS dial goes to 9).

Note: The module is set to 1 by default. For proper operation, you must change this to a different address.

The following table shows how to set the dials for some example addresses.

To set this address	TENS dial	ONES dial
2	0	2
21	2	1
135	13	5
150	15	0

If the dials are set to a number higher than 99, and the panel supports only CLIP, then the panel will see the device as an unrecognized device at address 0.

The MS-401AP(U) and MS-407AP(U) count as one address, which is set by the dials on the addressable module.

The MS-402AP counts as two addresses. The first address represents the PULL handle, and is set by the dials on the addressable module. The second address is one number higher than the dial setting and represents the switch activated by the stage two key

For example, if you set the dials on the MS-402AP to the address M, then M represents the PULL handle, and M+1 represents the stage two key switch.

Note: Because the MS-402AP counts as two addresses, always set the dial address at least 1 below the maximum value. If the panel supports only CLIP, set the address no higher than 98, and if the panel supports AP, set the address no higher than 158.

Mounting

Pull down the handle so that the station is open.
Mount the station to a surface mounted box with the 2 included screws. Refer to Figure 3.
Close the station. Follow the instructions under Resetting the manual station on this page.

Using the manual station in case of fire

Activating the alarm

Pull down the handle.
The handle is now hanging down. A qualified person must reset the station. See Resetting the manual station below

Activating the stage two alarm (MS-402AP only)

Insert the stage two key into the keyhole inside the station, and then turn the key. This keyhole is accessible only after the alarm has been pulled.
The stage two alarm activates.
Note: The stage two alarm will activate automatically a certain amount of time after the handle has been pulled. This time is set in the Fire Alarm Control Panel. You can prevent the stage two alarm from activating automatically by using the Automatic Alarm Signal Timer Cancel feature on the Fire Alarm Control Panel. Refer to the Fire Alarm Control Panel manual for instructions.

Resetting the manual station

Note: Resetting the station does not reset the alarm.

Insert a small flathead screwdriver into the hole in the front of the handle. Make sure that the end of the screwdriver is resting on top of the latch inside the station. The screwdriver must push down this latch order for the handle to close.
Close the handle and at the same time, move the handle of the screwdriver up. See Figure 4. As you close the handle, the screwdriver acts as a lever to push the latch down, allowing the handle to close. You will hear a click when the handle is closed and the station is reset.
Insert the glass rod (break glass) into the hole on the right side. See Figure 4.
Reset the Fire Alarm Control Panel to reset the alarm.
