Fireclass 557.180.423FC TM520 Timer Module Non-Addressable
Fireclass 557.180.423FC TM520 Timer Module Non-AddressableThe 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.The TM520 requires a separate 24Vd.c. supply to operate. The module is not addressable and will therefore not take an address on the loop.Key FeaturesEN54 -13 approvedRequires separate24Vd.c. power supply
