2.3 PROGRAMMABLE OUTPUT (PGM)

Each keypad has one on-board PGM. A PGM is a programmable

output that toggles to its opposite state (i.e. a normally open PGM will

close) when a specific event has occurred in the system (see section

5.2 of this manual). Upon activation, the PGM can provide 50mA to

any device connected to it. If the current drawn is to exceed the current

limit, a relay should be connected to the PGM as shown in Figure 2.1.
