Disabling and enabling devices 
Disabling a device prevents the VM-1 control panel from processing status 
change signals from the device, or changing the output state of the device, until 
the device is enabled. For example, the VM-1 control panel does not generate an 
alarm active event when you activate a disabled detector, but will do so after the 
detector is enabled. 
The VM-1 control panel keeps track of how many times you disable and enable a 
device. You must enable a device the same number of times you disable it in 
order to return the device to its initial condition. 
Device addresses are listed in Appendix A “System addressing” on page 45. 
Notes 
•  You cannot disable a device configured as a common alarm output. 
•  Disabling the device address for the dialer or a dialer account deletes all 
event messages sent to that account before they are transmitted. The dialer 
still transmits the account’s test-abnormal message and any message that 
was in the dialer queue before the account was disabled. 
•  Disabling all of the devices in a zone group automatically disables the zone 
group. Enabling any device in the zone group automatically enables the zone 
group. 
To disable a device: 
1.  From the Main Menu, choose Disable. 
2.  Choose Device, and then enter the device address (PPCCDDDD). 
3.  Enter the access level password.
