ACSI 1310-4 Mortise Keyswitches Narrow style, 1-3/4" frame mount

The ACSI 1310-4 is a key-operated switch that controls electric locks, electric strikes, electric exit devices and other control applications. Instead of a pushbutton anyone can press, access is by key, so the opening only releases for someone carrying the right key. It is a commercial access control device, not a residential one.

Yes. The 1310-4 is the narrow style version built for mounting in a 1-3/4 inch frame, which is the typical narrow face of an aluminum storefront or hollow metal frame. If your frame face is wider and you want a wider plate, the 1310-4 is the wrong variant to order.

That is the reason to choose a mortise keyswitch over a pushbutton. The 1310 Series accepts keying so the electrically controlled openings can be brought onto the facility master key system, meaning the same key that works the mechanical doors also releases the electric lock or strike.

It comes down to who should be able to open the door. The ACSI 1310-4 requires a key, so release is restricted to keyholders and can be tied into the facility master key system. A pushbutton is unrestricted, anyone at the door can press it. For free egress or a reception release, a button like the Securitron PB3 or the RCI 908 Series electronic exit button is the right call. For an exterior or restricted opening where you do not want a button anyone can hit, use the keyswitch.

No. The ACSI 1310-4 is not ADA compliant and requires a key to operate. For a barrier free actuator, the RCI 950 Series round push plate carries the handicap symbol and is a momentary switch in satin stainless steel, and the DynaLock 6210 Series palm switch buttons are alternate action SPDT devices sized for palm operation. A keyswitch like the 1310-4 is normally used alongside such an actuator for authorized override, not in place of it.

The Trine 342 is a narrow style electric door switch, which makes it the nearest match in form to the ACSI 1310-4 mortise keyswitch for narrow 1-3/4 inch frame mounting. Both are narrow profile switches intended for door control rather than wide push plates. The ACSI 1310 units are keyed, so they can be tied into a facility master key system and carry DPDT contacts unless otherwise noted, which is the deciding difference if the opening must be released by key rather than by a button.

Use a push button. The Securitron PB3 Series push buttons and the Securitron PB4L illuminated halo stainless push button both release an opening on press, with no cylinder or key involved. The RCI 908 Series electronic exit button with red EXIT text uses maintained operation, and the DynaLock 6115A is a one pushbutton, 1 gang alternate action device. The ACSI 1310-4 differs in that it is a mortise keyswitch, so only a keyholder in the master key system can operate it.

DPDT contacts are standard on the 1300 Series keyswitches unless a particular model is noted otherwise. Double pole double throw gives you two independent sets of transfer contacts, so one key turn can release a lock and simultaneously shunt an alarm or signal an access control panel.

Yes, electric exit devices are one of the stated applications for the 1300 Series keyswitches, along with electric locks and electric strikes. With DPDT contacts you have enough poles to both fire the device and pass a second signal back to a panel or annunciator.

The ACSI 1310-4 is a narrow style mortise keyswitch for 1-3/4 inch frame mounting and is specified for commercial door control of electric locks, electric strikes and electric exit devices. Where the control point is exposed, the DynaLock 6171 Series is a weatherproof pushbutton with a blank faceplate, which is the peer built for outdoor placement. It is a button rather than a keyed device, so it does not provide the master key control the 1310-4 gives.

Two to rule out. The DynaLock 6300 Series audible annunciator runs on 6 to 28 VDC and signals a condition rather than switching a lock, so it does not replace a control switch. The Securitron EEB emergency exit push button with interchangeable LED lenses is intended for emergency release and is not an everyday keyed control point. The ACSI 1310-4 is a mortise keyswitch that switches control of electric locks, strikes and exit devices and carries DPDT contacts unless otherwise noted.

The ACSI 1310-4 keyswitch carries DPDT contacts unless otherwise noted, which supports maintained control circuits for electric locks and strikes. Among button style peers, the RCI 919 Series rotary release button has maintained operation in satin aluminum, the RCI 908 Series exit button is a maintained unit, and the DynaLock 6115A is alternate action. By contrast the RCI 950 round push plate and the RCI 909F flush mount rocker switch, rated 250VAC 10A in beige, are momentary devices.

The ACSI 1310-4 is a narrow frame mounted mortise keyswitch with no illumination called out. If the control needs to be found in low light, the Securitron PB5 Series is a medium round illuminated push button and the Securitron PB4L has an illuminated halo with a stainless push button. The RCI 908 Series carries red EXIT text on the face. All of those are unkeyed, so they release to anyone at the door, unlike the keyed 1310-4.
