The callpoint is designed to monitor and signal the condition of a switch contact that is operated by breaking a glass sheet. Any change in the status of the switch is immediately communicated to the control panel.
The MCP820 has an integral short-circuit isolator for monitoring the field wiring. The MCP820 callpoint meets the requirements of EN54 Pt. 11 and EN54 Pt. 17.
Features
// Communication and control interface to MZX Technology Fire Controllers
// Approved to EN54-13 ensuring system compatibility
// Integrated short-circuit isolator removes the need of installing a seprate short-circuit isolator
// Reduced installation costs
// Meets the requirements of EN54 Pt. 11 and EN54 Pt. 17.
The MCP820 consists of a switch contact which is operated by breaking the glass sheet. When the callpoint is addressed by the control panel, it signals the condition of this switch contact to the control panel. The LED on the front of the callpoint is normally OFF, until the glass is broken, then it is turned ON until the glass is replaced. Incase of any emergency situation, the LED is illuminated in red to indicate the ‘ALARM’ condition.
The callpoint is resettable, it can be tested at any time with the aid of the callpoint test key provided. Insert the key fully into the bottom of the housing and pull down and remove, to release the bottom of the housing and break glass element. To reset the callpoint, slide the bottom of the housing upwards until it locks in position. If a section of the loop wiring adjacent to the MCP820 is shorted, the built in shortcircuit isolator trips, isolating the shorted section. The LED is illuminated in yellow to indicate that the isolator is tripped. This status remains until the short is removed.
