I recall running across a UL requirement that the unit be enclosed in an acceptable enclosure. This may be an issue if you are seeking to get a discount on your homeowner's insurance.
I re-read through the ELK M1 manual and it's misleading because one section does not mention an enclosure requirement for household burglary/fire, but a later one does:
Household Burglary (UL 1023), Household Fire (UL 985), Digital Alarm Communicator (UL 1635) Listed Installations
* At least one compatible keypad is needed for all applications.
* At least one bell fixture is required for all applications.
* Household Burg requires 4 hours of standby power. Limit combined continuous current draw from terminals +SAUX, +VAUX, +VKP, and
connector J16 to 1 Amp max. and use one (1) 8 Ah battery.
* Household Fire/Home Health Care requires 24 hours of standby power. Limit combined continuous current draw from terminals +SAUX,
+VAUX, +VKP, and connector J16 to 500 mA and use two (2) 8 Ah batteries in parallel.
* Force Arming and Auto Arming shall not be enabled
* For Household Fire Listed Installations the indicating devices shall be a Wheelock 34T-12 or equivalent.
* Initiating and indicating devices must be rated at 11.5 to 12.4 VDC.
* For Household applications the minimum alarm cutoff time for the audible devices shall be 5 minutes.
* Zone Swinger Shutdown shall not be enabled.
* Remote Downloading shall not be used on UL Listed systems.
* Communicator Dial Delay time shall be set to “0”.
* For Household Burg Listed Installations the maximum entry delay time shall be 45 seconds and the max. exit delay time shall be 60 seconds.
* 24-hour communicator test transmission is required.
* The silent keypad option shall not be enabled.
The later section that seems to indicate that an enclosure is a requirement:
LISTED ENCLOSURES:
For Household Burglar or Household Fire Listed Installations one of the following enclosures must be used:
* ELK 14” Enclosure model ELK-SWB14 or ELK-UB14
* ELK 28” Enclosure model ELK-SWB28

For Commercial Listed Installations one of the following enclosures must be used:
* ELK-TB14 Tamper Resistant Enclosure
* GE “Caddx” NX003-C with an ELK-61205684 Mounting Adapter Plate (See diagrams below)
Also, it seems to be a definite requirement for commercial applications:
Commercial - Central Station (UL 1610), Police Station Connected (UL 365), Local Burglar Alarm (UL 609) Listed Installations
Requirements described under UL1023 plus:
* The Alarm Cutoff timer must be set to 00900 sec. (15 min.) or greater.
* UL Commercial Burg requires 4 hours of standby power. Limit combined continuous current draw from terminals +SAUX, +VAUX, +VKP, and
connector J16 to 450 mA max. and use one (1) 8 Ah battery.
* An acceptable Commercial enclosure must be used (see Listed Enclosures below)
* A UL LIsted Tamper Switch(s) must be installed on the enclosure and connected to a 24 hour Burg Tamper defined Zone.
* All Keypads need to be installed within the protected area (they have no tamper)
* DO NOT USE an A B Attack Cabinet for the external sounder
* A Whenever/And/Then rule should be written (using ElkRP software) to enable the Output 2 Siren to ‘chirp’ upon closing ringback.
Does anyone know more about this issue? Is it a moot point because DIY installs can never be officially UL compliant anyway?
