==================================
π Pre-Wiring Requirements β Bosch Alarm System
Assuming: Keypads, Internal Siren, External Siren/Strobe, PIRs, Reed Switches
πΉ 1. PIR Motion Sensors
Cable:
-
1 Γ 6-core security cable (stranded, 0.5 mm) from each PIR β alarm panel location.
Notes:
-
4 cores required (12V+, GND, Zone, Tamper), extra 2 cores for redundancy.
-
Mount PIRs at 2.2β2.4 m height.
-
Avoid pointing directly at windows or heat sources.
πΉ 2. Reed Switches (Doors/Windows)
Cable:
-
1 Γ 4-core security cable from each reed β panel (or a junction loop).
Notes:
-
2 cores for the switch, 2 for tamper or future use.
-
Drill into the hinge side of the door frame when possible.
πΉ 3. Keypads (Bosch LCD / Icon / Touchscreen)
Cable:
-
1 Γ 6-core security cable from keypad β alarm panel location.
Location Requirements:
-
Mount at light switch height near main entry.
-
If using the Bosch touch keypad: a GPO nearby is optional (some touch models use 12V only, but safe to allow a GPO if unsure).
πΉ 4. Internal Siren
Cable:
-
1 Γ 4-core security cable from panel β internal siren location.
Notes:
-
Mount high in the hallway or central area.
-
Usually wired as +12V, GND, SIREN+, SIRENβ.
πΉ 5. External Siren / Strobe
Cable:
-
2 Γ 4-core cables from alarm panel β external siren box.
-
Cable A: Siren connections
-
Cable B: Strobe / tamper / backup battery monitoring
-
Location Notes:
-
Mount high and visible.
-
Allow good accessibility for future service.
πΉ 6. Alarm Control Panel Location
Panel Requirements:
-
1 Γ GPO (for the Bosch plug-pack power supply)
-
1 Γ Data point (RJ45) optional but recommended if integrating with IP modules (B426, B450, cloud apps).
Cabling:
-
All device cables (PIRs, reeds, keypad, sirens) should terminate at the panel.
Location Tips:
-
Garage, linen cupboard or comms cupboard is ideal.
-
Avoid hot roof spaces.
