Tyco TM520 Timer Module 557.180.423
The Tyco TM520 557.180.423 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 timed delay (set between 10 minutes and 2 hours 10 minutes) is started. When the delay reaches zero the TM520 output is activated.
Tyco TM520 557.180.423 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 module connected via a CIM800 Contact Input Module or MIO800 Small Addressable Multi-Input/Output Module. The TM520 provides two sets of three volt free contacts (Common, Normally Open and Normally Closed).
The Tyco TM520 557-180-423 requires a separate 24V DC supply to operate. The module is not addressable and will therefore not take an address on the loop.
