Each module can be licensed individually and uploaded to the Callisto platform at runtime. Callisto has no limit on the number of modules or users and is, therefore, future and investment-proof. The platform is only limited by the number of simultaneously used lines on a system, which can be up to 960 lines per system.

  • Triggering of silent alarms
  • Bidirectional communication possible (e.g., person search)
  • Active room monitoring and triggering of an alarm when a certain volume level is exceeded, possible through an active IP phone

Additional Features

The Callisto module ProfAlarm also supports many other features, such as:

  • Unlimited number of participants for the announcement of an emergency or disaster
  • Alarm confirmation of the participants also on mobile devices
  • Integration of field staff through mobile phone
  • Interruption or overlay of an ongoing telephone call for the signaling of a pending alarm (possible with Cisco phones)
  • Loudspeakers of IP phones can be used for announcements
  • Expandable with SIP-compatible loudspeakers (prerequisite: the devices must support automatic call acceptance)
  • If necessary: Direct multicast from Cisco phone to other Cisco phones configurable
  • Reporting: Clear logging of events
  • You can flexibly combine other Callisto modules and functions
  • Minimal use of network resources

Example 1: Alarm at the Push of a Button

Panic in public administration: A person is verbally threatened. The emergency teams immediately receive the incoming alarm on their terminals and can also acknowledge it depending on the configuration. Regardless of whether a small button under the desk or a giant red mushroom button is used, the alarm is recognized by Callisto when the button is pressed and triggered as a silent or loud alarm according to the specifications.


Example 2: Technical Alarm

An elevator door is blocked. Immediately, the elevator’s alarm transmitter reports the mishap to Callisto through the ESPA interface. Callisto sends the alarm as a sound and text message to the (mobile) telephones of the corresponding task forces.

Example 3: Evacuation

A fire has broken out in a building. Callisto receives the alarm information and activates the loudspeakers and telephones relevant in this zone via multi-cast depending on the fire zone. A manual, PIN-protected announcement for events that lead to an evacuation of buildings or subzones is also possible.

Example 4: Fire Patrol

A fire patrol regularly monitors a building or a ship. The tours, checkpoints, and the participants of the patrols can be defined in Callisto. From each checkpoint entered, the corresponding patrol must report in a particular time slot; otherwise, an alarm is triggered. You can consult a detailed report to evaluate the tours and alarms.

Example 5: Coordinating Task Forces

The company ambulance has an operation due to toxic gas. The responsible team is alerted through a defined Callisto number for this alarming case. To let the incident commander know who can participate in the operation, the individual members of the team confirm their participation or absence via (mobile) phone using key dialing. Afterward, the active members meet for short coordination via the Callisto alarm conference.

Example 6: Alarm System Integration

The customer has an existing alarm system that needs to work with a PBX. The primary alarm system is the Safety Monitoring and Control System (SMCS) on cruise ships. In order to be able to make escalations to telephones or mobile phones, the dedicated protocol from the corresponding SMCS has been integrated into the Callisto platform, which now handles the specific escalation scenarios via this interface.
