TM520 Timer Module

557.180.423

The TM520 provides an output that can be activated based on a delay time. If either the key-switch on the module is activated, or a predefined event within the control panel occurs then a times delay (set between 10 minutes and 21 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 the delay is nearly over, the red LED and the buzzer will pulse 5 minutes before the end of the delay.
