Summary
The Apollo XP95 Addressable Door Retainer (ADR) holds fire doors safely in the open position during normal operation, helping to maintain accessible routes through a building. When instructed by the fire alarm system, it releases the door so that it can close in accordance with the programmed fire strategy.
View full overview Show less
Designed for direct connection to an XP95 addressable loop, the retainer allows individual doors or groups of doors to be controlled through the fire alarm panel’s cause-and-effect programming. This supports targeted evacuation and lockdown strategies while removing the need for a separate mains-powered door-retention supply.
A 200 N holding force, integrated loop isolator and low-current permanent magnet technology provide reliable, fail-safe operation. When connected to a compliant control panel, the device is also suitable for BS 7273-4 Category A critical actuation installations.

FAQs
What does the Apollo XP95 Addressable Door Retainer do?
It holds a fire door in the open position during normal operation and releases it when instructed by the fire alarm system, allowing the door to close as part of the building’s fire strategy.
Does the door retainer connect directly to the fire alarm loop?
Yes. The device is loop-powered and connects directly to a compatible XP95 addressable loop, without requiring a separate mains-powered door-retention supply.
Can the retainer be used for Category A installations?
Yes. Direct connection to a control panel with supporting BS 7273-4 Category A functionality allows the retainer to be used for Category A critical actuation applications.
Can individual doors be controlled separately?
Yes. Its addressable operation allows individual doors or zones of doors to be controlled through the fire alarm panel’s cause-and-effect programming.
What is the holding force of the door retainer?
The retainer has a rated holding force of 200 N.
How long does the retainer take to initialise?
The current manufacturer documentation specifies a minimum initialisation and self-check period of 90 minutes while continuous loop power is present. The retainer may not operate until this process has been completed successfully.
Does the unit have a manual release?
Yes. A manual release switch is supplied, allowing the retained door to be released locally when required.
How can the door retainer be mounted?
The unit can be surface mounted or semi-flush mounted onto a wall. Floor mounting is also possible using a suitable standard bracket.
What do the status LEDs indicate?
The twin LEDs indicate charging, normal charged operation, loop isolator activation and device fault conditions. Monitored faults include a loss of protocol communication and insufficient loop power.
Under what conditions will the door remain held open?
The device must have loop communication, sufficient charge, a valid address and no active device faults. The control panel must also not be indicating an alarm condition requiring the door to release.
How often should the door retainer be tested?
Fire door retainers should be tested weekly as part of the fire alarm system test procedure. The magnet and keeper plate should also be kept clean and free from damage to maintain the optimum holding force.
