SS Signal switch

Popular SS Application

Unauthorized use of this opening will activate the local horn. The

key switch permits inhibiting this system for authorized entry.

Monitors pushpad and latch bolt

The SS feature is used to signal the unauthorized use of an

opening. This device is equipped with two internal SPDT

switches. One switch monitors both the pushpad and the latch

bolt assembly, making the latch bolt tamper resistant, for

positive security. An additional SPDT switch is connected to the

/4" (32mm) mortise cylinder with straight cam for alarm

“bypass.” (Schlage cam reference B502-191). The device can be

connected to a security console, or may be used as a single door

alarm when used with a horn and power supply.

Pushpad reads: “Emergency Exit ONLY – Push To Open And

Sound Alarm.” Pushpad is only available in US32D ﬁnish with red

silk-screened lettering.

The SS mortise lock device is furnished with both the signal

switch device and the SS7500 mortise lock. The SS7500 mortise

lock has the versatility and advantages of the 7500 lock with the

addition of signalling functions to monitor latch bolt operation

and the trim locking function. The SS7500 mortise lock is

supplied standard with the SS mortise lock device.
