Alarm Lock Trilogy T2 DL2700 Keypad Lever Lock, Grade 1, 100 User Codes

The DL2700 retrofits a standard 161 cylindrical prep: a 2-1/8 in bore with a 1 in latch hole at 2-3/4 in backset. Alarm Lock's template WI838D adds two through-bolt holes above and below the bore, two more holes near the top of the housing and a wire hole.

1-5/8 to 1-7/8 in as standard. Alarm Lock makes extended locks for thicker doors and a spacer set, S6072, for doors 1-3/8 in or less. Tell us the thickness; it goes on the order.

The lock ships with a 2-3/4 in latch. A door bored at 2-3/8 in takes the S5980-1 latch, in 26D; tell us and we quote the two together.

Standard models come with an SC1 keyway cylinder and spare tailpieces, so a Schlage, Corbin Russwin CL, Sargent 480, ASSA 65-611, Ilco or Lori key-in-knob cylinder from your system can be fitted instead. If the building uses interchangeable cores, order the DL2700IC with the prep for your core brand; the core is not included.

Alarm Lock's current T2 series sheet says every Trilogy is weatherproof as standard, -31 to +151 °F (-35 to +66 °C). Its instruction sheet asks for the connectors to be sealed with dielectric grease (MX959) or the silicone lubricant supplied.

Choose the DL2700CR (classroom function) or DL2700DB (deadbolt function). Both are handed, left or right, and field reversible, with a 1-3/8 in mortise cylinder and a 2-3/4 in backset. Tell us the door hand when you order.

The DL2700LD adds a keyfob that puts the lock into lockdown and a red indicator bar on the inside of the door. During lockdown only master and manager codes open it from outside, and the inside lever still lets people out.

The lock's two remote release wires take a normally open push button, for example at a desk. Alarm Lock's RR-TRILOGYKIT instead adds a desk-mount button and a receiver that fits in the battery compartment of a cylindrical Trilogy.

Alarm Lock lists the latchbolt as UL listed and fire rated for 3 hours, and its template marks a 1 in wire hole for fire-rated doors in a different place from the 7/8 in hole used on other doors. Whether the lock may go on your door is for your AHJ.

Tell us first. Alarm Lock warrants the lock for 24 months from its date of manufacture, and we take up a claim with the original invoice. To replace an older lock, send a photo of both sides of the door and the lock edge.

Print template WI838D at full size and check its dimensions first, as Alarm Lock asks. It marks the 2-1/8 in bore and 1 in latch hole at 2-3/4 in backset, two 3/8 in through-bolt holes above and below the bore, two more 3/8 in holes near the top and the wire hole.

The template puts a 1 in hole 2-5/8 in above the bore centre on fire-rated doors. The 7/8 in hole 3-9/16 in above it is for doors that are not fire rated.

Alarm Lock's instructions give a start-up sequence with the batteries disconnected, and nothing else can be programmed until the factory master code is changed. The new master code sets the length of every later code, 3 to 6 digits; Alarm Lock recommends 5 or 6.

Five 1.5 V AA alkaline batteries; Alarm Lock's instructions name Duracell. Change all five together. The lock keeps its programming, but the three one-time service codes are lost whenever power is removed.

Remote release: a normally open switch on the two white wires. Auxiliary relay: blue common, yellow normally open, green normally closed, 300 mA at 60 V DC maximum. External power: 7.5 V DC, at least 100 mA, black negative and red positive, from a UL listed supply with battery backup.

Seal every connector with dielectric grease (MX959) or the silicone lubricant supplied, as Alarm Lock's instruction sheet WI1822A asks.

Erase All Programming returns the lock to its factory master code and deletes every code. It starts with disconnecting the battery pack in the inside housing, so it is done from inside the door.
