Bosch CM255B Panel Default Unlock Key for Solution 6000
The Bosch CM255B is the way into a Solution panel whose installer PIN nobody knows: a single-use plug-in key that resets the installer PIN and RAS security PIN on a Solution 6000, so the panel is taken over on site instead of being unwired and returned for defaulting.
What you get
- 1 × CM255B factory default module, blue, with red and green status indicators, for one use only
You'll also need
- Access to the panel board and its 10-pin connector marked Serial Port or Direct Link Port, such as on the CC610P
- A new key for every panel defaulted, because a used key cannot be used again

§ 01Overview
What the CM255B is
The Bosch CM255B exists for one situation. A Solution panel arrives second-hand, or an installer moves on, and the installer PIN is gone. When factory defaulting has been disabled in panel programming, the current installer PIN is needed to default the panel, which leaves two options: return the panel to the supplier, or unlock it in the field with this key.
The key plugs into the 10-pin connector marked Serial Port or Direct Link Port. A steady green LED means the key is good; red and green flashing alternately means defaulting has been initiated and the key can be removed and thrown away; a steady red LED means the key has already been used and cannot be used again.
What gets reset depends on the panel. On a Solution 6000 it unlocks the installer PIN and the RAS security PIN, after which the panel is entered with the default installer PIN 1234 followed by MENU. On a Solution 16i, 16+ or 64 it performs a complete factory default, and on a Solution 144 it defaults only the installer code and RAS PIN.
It is a one-time-use device, discarded after use, and it carries no warranty because of its disposable nature. Budget one key per panel, and keep it for lost codes: a panel whose installer PIN is known does not need defaulting at all.

CM255B specifications
Solution 6000 — unlocks the installer PIN and RAS security PIN — the way back into programming when the codes are lost
Other panels — complete factory default on Solution 16i, 16+ and 64, installer code and RAS PIN only on Solution 144 — know which result to expect before plugging in
Connection — 10-pin connector marked Serial Port or Direct Link Port, orientation matters — no wiring changes to the panel
Indicators — green steady is good, red and green alternating is defaulting under way, red steady is already used — the key reports its own state
Single use — one time use only, discard after use — one key per panel
Warranty and marks — no warranty because it is disposable, N12138 and RoHS marked — a consumable, priced as one
