B. 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.
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.

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)
1. 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.
1. 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.
2. 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.
3. Insert the glass rod (break glass) into the hole on the right
side. See Figure 4.
4. Reset the Fire Alarm Control Panel to reset the alarm.
