The TM520 provides two outputs that can be activated based on a delay time. If the key-switch on the module is activated or a predefined event within the control panel occurs, then a timed delay (Between 10 mins and 2 hours 10 mins) is started. When the delay reaches zero the TM520 outputs are activated. The unit sounds an internal buzzer and illuminates a red LED when the outputs are active and illuminates a yellow LED when the timer is counting down. The red LED and the buzzer will pulse 5 minutes before the end of the delay. Technical Information: Powered:24V DC Temperature Range:-20°C to +70°C Operating Humidity: Show more
