Description
This wall-mount strobe provides visual fire alarm notification with four field-selectable candela settings: 15, 30, 75, and 110 cd per UL 1971. It operates on 16–33 VDC or VFWR and produces one flash per second over the full input voltage range using a Xenon flashtube enclosed in a Lexan lens. The strobe inputs are polarized for compatibility with standard reverse-polarity NAC circuit supervision by Siemens fire alarm control panels.
Strobe synchronization is supported through Siemens DSC sync modules, the Siemens 50-point, 252-point, and 504-point addressable FACPs, FireFinder XLS and MXL panels, and PAD-3 or PAD-4 NAC extenders with built-in sync protocol. If the sync source fails, the strobe reverts to a non-synchronized flash rate. Removal of the appliance from its base plate generates a trouble condition at the panel.
The ZR-MC-R uses the EZ Mount universal mounting plate (ZB series), which supports single-gang, double-gang, 4″ square, and 4″ octagonal backboxes. The base plate can be pre-wired and circuit-tested before the appliance is snapped on, and ships with a disposable dust cover to protect terminals during construction.
