Eaton LCD Alarm Keypad with Proximity Reader for M-Series Panels MKP3

What this keypad is for

A keypad is where people set and unset an alarm and read its messages. When one fails on an older system, the panel may still have years of use left, and replacing the keypad is the simple fix.

That is the job of this Eaton part. It is a service part for existing panels, not a keypad to plan a new system around.

How proximity works

• Coil and tag: the keypad contains a coil that works at a low radio frequency. A tag held close is detected, and that sets or unsets the system.
• Spherical detection area: the detection area extends for approximately 120mm from the keypad in all directions, so the tag only needs to come close.
• Anti-masking: this is detection of a device being covered or blocked. The 2 keypad zones support it, on a panel that also supports masking.

Where to use it

It goes on an existing system built around one of the listed M-series panels. It cannot be used with flush mount kits, so check how the old keypad was fixed.

Environmental Class II and an operating range of -10 to 55°C point to indoor use. Keep it in a dry, protected spot near the entry route.

Using it on a TS panel

• Mask link: make sure this is unlinked, as some TS panels do not support masking.
• Different keys: you will have UP, TOGGLE, DOWN and HASH keys in place of A, B, C, D. The functions match, but tell the user, as their manual will name different keys.
• Mixed keypads: avoid mixing old TSNETLCD keypads and new MKP3 keypads on the same network.
• Tags: using proximity tags depends on the panel software: TS690/M/iD/iDM Version 5.1.

What the figures mean in practice

• 90mA max @12Vdc: add this to your load when checking the panel's supply and battery. With an external reader or a load on the output, check again.
• Switched -ve, 100mA max.: the output switches negative when active, and suits a small load such as a relay or an indicator. Check any device against this limit.

Planning your system

Before ordering, read the panel's model off its board or manual and compare it with the list. If it is not there, a different keypad is the safer choice.

Plan for tags unless the site already has them. The KEY-EP external reader is an option if a tag point is wanted away from the keypad.
