Key takeaways
- The DL2700's code levels are a Master code, 10 manager codes, 90 user codes and 3 one-time service codes, and Alarm Lock's spec sheet gives the capacity as up to 100 different user codes of 3 to 6 digits.
- The DL3200 is the audit-trail model: 2000 multilevel user codes, a 40,000-event audit trail, 500 scheduled events, quick passage mode and a programmable remote release.
- Both models run on 5 AA batteries, and Alarm Lock's catalog gives the same typical life for each: 200,000 cycles or up to 5 years.
- Alarm Lock's DL2700 spec sheet describes weatherproof and standard interior models, while its 2026 catalog says all Trilogy DL/PDL models are now weatherproof as standard, -31 to 151 degrees F.
- The PG21 is a key-activated door alarm from Alarm Lock, not a Trilogy keypad lock.
Which Trilogy lock do I have?
Alarm Lock's model names group Trilogy into the T2 keypad locks, the T3 audit-trail locks and the networked Trilogy Networx locks. The DL2700 is the T2 cylindrical lock; the DL3200 is the T3 Digital Cylindrical Enhanced Audit Trail Lock. Other models differ in what you can see on the door: a touch keypad, a built-in prox card reader, a mortise lock body, or exit trim on a panic bar.
For how a standalone keypad lock differs from a system managed from software, see keypad lock or managed access control. Alarm Lock lists more models than the table below. Its DL2700 spec sheet says Trilogy is available in many additional models, including those for outdoors, mortise, exit trim panic devices, a Prox ID card reader, dual-sided keypads and wireless lock networks.

DL2700
DL2700 codes, keypad and manuals
The DL2700 holds up to 100 different user codes of 3 to 6 digits, and the levels are in the table below. It is 100% keypad programmable with a fingertip, and the catalog writes its capacity as "100 +3 +1".
The keypad is all metal with 12 buttons, has 4 keypad tones and can be silenced. Its programmable functions include group or individual user codes, master and management codes, passage and emergency or service code, lockout and remote override capability, and an allowable entry time from 5 to 20 seconds.
Other listed features are a 2-wire remote override, individual, group or total user lockout codes, and a passage mode by manager or master. A clutch lets the outside lever turn freely in the locked position without retracting the latch. In the spec sheet's words, "Inside lever always instant egress".
Alarm Lock's instruction manuals page lists DL2700 installation instructions, DL2700 (Enhanced, 100 Users) programming instructions and DL3200 programming instructions. The DL2700 programming manual also covers the TL2700 and has sections on wiring, quick start, testing codes, code location worksheets, audible and LED indications, battery replacement and the limited warranty. This page does not reproduce programming steps or codes.
The spec sheets name the maker as Alarm Lock Systems, LLC (A Division of NAPCO Security Technologies, Inc.). Alarm Lock says it sells solely to security professionals, through independent security and locking distributors, contract hardware suppliers and wholesalers, and its manual notes that technical service is for security professionals only.
| Code level | How many | What it can do |
|---|---|---|
| Master | One | All functions |
| Manager | 10 | Most functions, plus entry through the door |
| Basic user | 90 | Entry only |
| Service | 3 | One-time entry |

DL2700
DL2700 batteries, door fit and ratings
The DL2700 runs on 5 AA alkaline batteries, supplied and now rated at 200,000 cycles. Alarm Lock's product page gives "5 years battery life or 200,000 cycles, typ."
It has an audible low battery alert and visual and audible entry indicators, and the battery compartment sits in the inside housing, on the inside of the door. The lock is non-handed, so one model fits left- and right-hand doors, and it retrofits cylindrical knobsets and digital locks using a slightly modified door prep.

DL3200
DL3200 audit trail and schedules, beside the DL2700
The DL3200 replaces the DL2800 with more features than both the DL2800 or DL3000. It holds 2000 multilevel user codes of 3 to 6 digits with more one-time service codes, a 40,000-event high capacity audit trail and 500 scheduled events.
It also has a programmable remote release and quick passage mode. Alarm Lock's ordering list names DL-WINDOWS as free Trilogy Windows-based database software.
The catalog states the DL3200's programming two ways: its feature list says "Keypad or PC programs/reports", while the table on the same page says "Keypad only".

T2 family
Lockdown, mortise, narrow stile, exit trim and touch T2 models
The catalog table lists four more T2 models with the DL2700's "100 +3 +1" user codes and keypad programming, grouped under electronic standalone locking in cylindrical, mortise, narrow stile and exit trim.
The DL2700LD is the DL2700 with lockdown by keyfob. The supplied remote keyfob locks down up to four locks, a lock takes up to 50 keyfobs, and a visual lockdown indicator bar, also included, sits on the inner door.
Trilogy Touch is the touch-keypad version. The TL2700 is the Trilogy Touch cylindrical lock with the functionality of the DL2700, and the programming instructions say the two are identical in operation but with different keypad types.
| Model | Lock type | Code length | Cylinder | Battery/cycles typical | Notes |
|---|---|---|---|---|---|
| DL2700CR/DB | Mortise | 3-6 digits | 1 3/8 in. mortise cylinder, supplied | 5AA; 60000 | Classroom (CR) and deadbolt (DB) versions; handed, field reversible |

T3 family
DL3000, PDL3000 prox lock and DL3500 mortise lock
The DL3000 is the original audit trail Trilogy keypad lock, with 300 multilevel user codes and a 1,600-event log. The PDL3000 is a PIN and prox lock: its built-in HID prox reader takes HID prox ID cards and keyfob credentials, and each user is set to card only, code only, or card and code.
Alarm Lock's documents do not agree on the PDL3000's capacity, so the table gives each one's figures.
The DL3500 Series is the T3 mortise lock, in classroom or deadbolt function and left or right hand. It holds 300 user codes of 3 to 6 digits, up to 500 scheduled events and a 40,000-event audit trail, and it is fingertip or Windows PC programmable.
Its inside lever is always in passage mode and permits instant egress, and a single turn of the inside lever releases the latchbolt and the deadbolt where applicable.
The DL3500 sheet says all Trilogy mortise lock models are weatherproof and operate from -20 to 151 degrees F (-29 to 66 degrees C). Alarm Lock's mortise product page gives -31 to +151 degrees F (-35 to +66 degrees C).
| Document | What it gives for the PDL3000 |
|---|---|
| PDL3000 spec sheet | Up to 2000 users with prox ID cards or 3 to 6 digit codes; 500 scheduled events; up to 40,000 audit trail events |
| Cylindrical Pin/Prox product page | 2000 user codes; 40,000 event audit trail log; 150 scheduled events |
| Abbreviated catalog | Original audit trail lock with or without prox; 300 multi-level users; 1600 event log |

Networked models
Trilogy Networx and ArchiTech Networx
Alarm Lock's catalog calls Trilogy Networx the networked evolution of the Trilogy standalone locks. The wireless locks communicate over Ethernet or Wi-Fi, which removes door-to-door programming and audit trail retrieval.
Each door uses a wireless lock that communicates with a Multi-Lock Gateway, and each gateway supports up to 63 locks, depending on network environment, physical placement and building construction.
ArchiTech Networx locks have a designer, minimalist look and concealed electronics, with all the features and networking functions of Trilogy Networx and hundreds of trim and finish combinations.
| Model | Lock type | User codes | Programming | Audit trail events | Scheduled events | Battery/cycles typical |
|---|---|---|---|---|---|---|
| PDL6200 | Cylindrical | 5000, 3-6 digits | Keypad / PC | 35000 | 500 | 4 C cells; 500,000 or up to 5 years |
| P/DL6600 | Mortise | 5000, 3-6 digits | Keypad / PC | 35000 | 500 | 5AA; 60000 |
Source Alarm Lock's abbreviated catalog (7.2026), pages 4, 7 and 8.
PG21
The PG21 is a door alarm, not a keypad lock
Alarm Lock's PG21 Advanced Door Alarm Series is a surface-mount, microprocessor-controlled, key-activated door alarm for standard size and narrow stile doors that uses a standard mortise cylinder. Its spec sheet presents it as a response to doors being propped open, under the header "From the makers of Trilogy".
| Item | PG21 |
|---|---|
| Arming modes | Two |
| Entry delay options | 15 seconds, 1 minute 15 seconds, 3 minutes 15 seconds |
