Keypad Address
Addressing
The valid addresses for Galaxy keypads connected to a Galaxy 16/16 plus
control panel are 0, 1, and 2. A 16-way rotary address switch is used to address
Galaxy Mk III keypads. The address switch assigns a hexadecimal address
value to the keypad. The factory default address is 0.
Notes: Any change to the keypad address must be made when the power is
disconnected from the keypad.
Each keypad must have a unique address.
Keypads can have the same address as a RIO or Smart PSU.
Tamper Switch
The Galaxy keypads provide a tamper switch that operates when the keypad is
detached from the keypad mounting bracket.
The keypads are designed to allow the option of an additional wall tamper
which will cause a tamper alarm should the entire keypad (including the
mounting bracket) be prised from its mounting. The tamper spring retainer
(located on the Galaxy keypad mounting bracket) can be knocked-out to allow
the tamper spring contact with the wall, this enables the wall tamper, see Figure
3.2 Keypad Installation and Mounting Details.
Backlighting
When initially connected to the control panel, the keypad is permanently
backlit. The backlighting can be switched off and on using the shift function
keys, refer to
Star Key (
During an a.c. mains failure condition, to save the available stand-by battery
power, the keypad backlight is turned of until the a.c. mains supply is restored.
