When the delays are running during an alarm condition, a numerical countdown is displayed on the
screen to indicate time remaining before the expiry of the current timer.
T1/T2 can also be switched on and off/on using the input side of an I/O, MCIM or Call point
programmed to disable devices within the Site Installer input programming. (see page 23).
If T1/T2 is required on a site where these delays need to be active during certain times and turned off
at all other times, generally a member of staff would need to operate the call point or I/O.
However, within the T1/T2 menu is a feature called ‘Auto enable delays’. This feature enables the
user to automatically set T1/T2 at the required times as a backup if the input is missed.
A more recent amendment (July 2011) has introduced an automatic disable feature to run alongside
the auto enable feature. (see FIG 9)
