| All models are UL, C-UL and CSFM listed, and are compliant with the NFPA 80 requirement for a fail-safe door holder/releasing device. The various models include common features such as a vibration-resistant latching mechanism for the fusible link connection, mounting flexibility and disruption-free testing capabilities. |
 |
-
Two adjustable time delays for power loss and alarm signals from a detector or remote switch to reduce costly door resetting caused by nuisance or false alarms.
-
Testing function allows routine fire door testing without requiring activation of the smoke detector or central alarm system.
|
 |
Includes all the Model A safety features, plus:
-
Downlimit detection prevents door release if the door is already in the closed position. Eliminates door reset service calls or potential system damage.
-
Form C dry contact relay output for activation of notification devices including horns and strobes.

Featuring a built-in batter pack, Model B2 provides the added functionality of a separate fire alarm panel. It is designed for installations where power outages are a regular occurrence or where an existing alarm system is not available or is unable to support the door release system.
Includes all Model B features, plus:
-
72-hour internal battery backup (with charger) provides power to the release device as well as up to 4 smoke detectors to prevent door release during long power outages.
-
Two SPDT dry contact relay outputs for both delayed and non-delayed activation of devices such as horns and strobes.
-
Two smoke detector loops (one normally closed and the other normally open)
-
12 VDC alarm output for an optional voice annunciation module
-
On-board diagnostics allow monitoring of battery charging circuit and alarm inputs

| Possessing the same features as the Model B2, the B2 Master can function as a "master" unit, operating up to three Model RR remote release "slave" devices. This combination of devices is designed as a cost-efficient means to address multiple door installations in close proximity, where closures can occur from a common alarm signal. The B2 Master and RR remote release devices are connected via a common "daisy-chain" wiring method, which reduces installation time and cost. The 72-hour battery backup feature of the B2 Master, the Model RR devices are fail-safe devices, as they are part of the fusible link assembly. |
