Manual Call Point Key Guide: Which Key Fits Your Fire Alarm MCP?

If you’ve ever been left frustrated trying different keys to reset a manual call point (MCP), you’re not alone. Fire alarm systems use various call point brands, and each brand often requires a specific key. Using the wrong one not only wastes time but can also delay important maintenance or cause unnecessary system faults.

This MCP key guide lists the most common manual call point keys and which brands they work with – saving you time during testing, maintenance, and emergency resets.

A manual call point key, sometimes called an MCP reset key, is a small tool used to:

• Reset a manual call point after it has been activated

• Open the call point for inspection or maintenance

• Test the call point without breaking the glass or activating the alarm unnecessarily

Because MCPs are designed to prevent accidental resets, you need the correct key for each brand or model.

1. KAC Call Points

• Common Keys: KAC T-Bar key, KAC new style key

• Used On: KAC, Honeywell, Notifier, Gent, and many other rebadged models

• Notes: KAC call points are the most widely used in the UK, and many other brands use KAC rebranded MCPs – so this is the key you’ll use most often.

2. Apollo Call Points

• Common Keys: Apollo reset key (different from KAC)

• Used On: Apollo Discovery, XP95, and Series 65 call points

• Notes: Apollo keys are shaped differently to KAC and won’t work interchangeably.

3. Hochiki Call Points

• Common Keys: Hochiki reset key

• Used On: Hochiki CCP-E and conventional call points

• Notes: Hochiki keys are manufacturer-specific, and you’ll need the right one for testing and resets.

4. Fulleon Call Points

• Common Keys: Fulleon reset key (compatible with some older KAC-style MCPs)

• Used On: Fulleon Roshni and conventional systems

• Notes: Often confused with KAC, but check your MCP before using.

5. Other Brands

• Gent: Uses KAC keys for many models, but always check as some older models have unique keys.

• Siemens: Siemens MCPs often have their own specific key.

• Advanced / Hyfire: Usually rebranded KAC MCPs, so KAC keys typically fit.
