Honeywell TC500K Manual Alarm Button

1. Overview

l The Honeywell TC500K Manual Alarm Button is a strong manual alarm button. It works with smart controllers. It has a built-in decimal coding switch for easy address setup. This two-wire device polarises and activates the fire alarm manually when someone breaks the glass.

l Upon activation, the alarm light illuminates, and the controller emits an alarm sound, displaying the alarm address simultaneously. You must install at least one manual fire alarm button in each fire protection zone. No point in a zone should be more than 30 meters from the nearest button.

l Models like the Honeywell TC500 thermostat, TC500A, and TC500A-N work well with modern safety systems. Variants like the J-SAP-M-TC500K, a durable manual alarm button, provide flexible installation options for various facilities.

l Honeywell also provides additional devices. These include the tc810n1013 module, tc810n1013c module, st3000 transmitter, std725 pressure transmitter, and std810 pressure transmitter. These devices improve safety and monitoring in industrial and commercial settings.

2. Manual Fire Alarm Button Placement

Place manual fire alarm buttons at the entrances and exits of public spaces. Ensure they are easily visible and accessible. If a fire hydrant box is nearby, you can install the button adjacent to it.

When mounted on a wall, the bottom edge should be 1.5 meters above the ground, with clear signage indicating its location. The button is available in surface and flush versions, depending on user requirements.

3. What is the K terminal on a Honeywell thermostat?

The K terminal on a Honeywell thermostat simplifies wiring for homes with limited wires. It merges the Y (cooling) and G (fan) terminals into one, allowing both functions to run through a single wire. This is particularly helpful when upgrading to a smart thermostat, such as the Honeywell TC500. You won’t need new wiring.

However, the K terminal only works with specific Honeywell models and requires a C-wire adapter module. Always confirm compatibility before use.
