SEC-H-600 SECURITY CONTROLLER
95-7759—07 4
WEBs-AX Security Enclosure
For a UL Listed system, the Security Controller, plus all expansion modules, must be mounted in one or more WEBs-AX Security 
Enclosures. These enclosures meet the UL 294 listing, have a pre-mounted DIN rail (or rails), and include a door with a key lock 
and tamper switch. Two models have an integral 30W 15Vdc power supply that powers the SEC-H-600 controller and/or the 
expansion modules inside the enclosure.
Fig. 2. Security Controller must be mounted in WEBs-AX Security Enclosure (model SEC-ENC-H-1 or SEC-ENC-H-2).
As shown in Fig. 2, there are 3 different-sized WEBs-AX Security Enclosures available, including these models:
SEC-ENC-H-1: (Medium) For the Security Controller in the smallest job configuration, or where additional expansion modules 
are located remotely (in other Security Enclosures). It provides a single DIN rail and an integral 30W 15Vdc power supply to 
power the controller, or up to two SEC-H-R2Rs, or one SEC-H-RIO. The controller (or modules) plug directly into the power 
supply, see Fig. 2. Brackets at the bottom of the enclosure secure one or two rechargeable sealed lead-acid backup batteries 
(batteries used only if a Security Controller is housed). In larger systems, more Security Enclosures can be used to house 
additional expansion modules. 
Another medium-sized enclosure without an integral power supply is also available, model SEC-ENC-H-1NP. It is used for 
expansion modules only (not the Security Controller), and it has room for one additional SEC-H-R2R module.
SEC-ENC-H-2: (Large) Used for the Security Controller in larger job configurations, it provides a DIN rail mount and an integral 
30W 15Vdc power supply for the controller, and a second DIN rail for expansion modules—for example, up to four (4) SEC-H-
R2R modules. The SEC-H-600 controller plugs directly into the power supply, see Fig. 2. A supplied six-conductor wiring harness 
(not shown) provides power and RS-485 communications to expansion modules mounted on the lower DIN rail. Brackets at the 
bottom of the enclosure secure one or two rechargeable sealed lead-acid backup batteries (backup batteries used only if 
enclosure houses an Security Controller). In larger systems, more Security Enclosures can be used to house additional modules.
Another large-sized enclosure without the integral power supply is also available, model SEC-ENC-H-2NP. It is used for 
expansion modules only (not the Security Controller), and it has room for one additional SEC-H-R2R module.

NOTE: In larger systems, additional

(no Security Controller), where backup 
batteries are not used. At right an SEC-
ENC-H-1 is used this way.
