SECURITRON MODEL MUNL-12, MUNL-24 MORTISE UNLATCH

INSTALLATION AND OPERATING INSTRUCTIONS 1. DESCRIPTION

Securitron’s Mortise UnLatch is a revolutionary new type of electric strike which eliminates the necessity to perform a routing operation on the door frame for installation. The motor driven Mortise UnLatch also presents a fully concealed appearance on the door which not only enhances architectural appeal but improves security over a conventional electric strike as an intruder is less able to determine the type of security device present on the door. The Mortise UnLatch functions with all North American mortise locks and includes a latch status output which reports when the door is in latched (secure) condition or is open.

Product Specifications are: Input Voltages: 12 VDC (MUNL-12), +20%, -10%. 24 VDC

(MUNL-24), +20%, -10%. Current: At rest: 40 mA (either voltage). When operating- 4 Amp input surge @ 12 VDC; 2 Amp input surge @24 VDC for 100 milliseconds and 600 mA @ 12 VDC or 300 mA @ 24 VDC during motor movement. Operating Temperature: -10°to 125° F.

2. PHYSICAL INSTALLATION

2.1 SURVEY

The installer must first be sure that the latch is of the mortise type (see the drawing to the right.) A mortise lock (or latch) includes a square shaped springlatch and a “pin” called the deadlatch pin or guard bolt which may be positioned either above or below the springlatch. Most mortise panic bar latches are also perfectly compatible with the MUNL. Note, however, that if the mortise lock assembly includes a dead bolt, the dead bolt will not be operable The most common alternate type of latch in use in North America is called cylindrical, tubular or bored. The standard UnLatch (model numbers UNL-12 and UNL-24) is designed for this alternate type of latch. Securitron does not offer an UnLatch solution for a rim latch (rim latches are on the surface of the door rather than being mortised into the middle of the door).
