Description
The QR Systems UDP-513-102A addressable remote release unit is intended for sending emergency signals to unlock evacuation and emergency exits in a QR Systems addressable fire alarm system and for directly unlocking the exits. It is used with the addressable analogue fire control and indicating panel and the KS-02-250 system controller; communication and power are over the wired PLS loop, and the unit occupies one address slot in the system. The built-in short-circuit isolator activates at 10 V and restores at 3 V, cutting off the damaged section of the loop. The housing is protected against accidental activation, has a tamper switch and LED status indication; the unit monitors its own operability and measures the PLS voltage at its installation point. An extractor key for resetting is supplied.
Advantages
- Manual unlocking of an emergency exit — evacuation starts on a person's command, without waiting for automation
- Built-in short-circuit isolator — damage to one section of the loop does not stop the other devices
- Protection against accidental activation and actuation force no less than 25 N — no release from an accidental touch
- Tamper switch and operability monitoring — the panel sees the unit's condition
- PLS voltage measurement at the installation point — loop diagnostics without additional instruments
- Current no more than 0.16 mA in standby and 0.2 mA on release, 10-year service life — economical, long operation
Applications
- Evacuation and emergency exits of office and administrative buildings
- Shopping centres, hotels and public buildings
- Educational and medical facilities
- Production and warehouse sites
- Sites with a QR Systems addressable fire alarm system based on the panel and the KS-02-250 controller
