The TM520 provides an output that can be
activated based on a delay time. If either the keyswitch
on the module is activated, or a predefined
event within the control panel occurs then a
timed delay (set between 10 minutes and 2 hours
10 minutes) is started. When the delay reaches
zero the TM520 output is activated. The unit
sounds an internal buzzer and shows a red LED
when the output is active, and shows a yellow
LED when the timer is counting down. To provide
a warning that the delay is nearly over, the red
LED and the buzzer will pulse 5 minutes before
the end of the delay .
The TM520 requires a separate 24V DC supply to
operate. The module is not addressable and will
therefore not take an address on the loop.
