BEST CM150-08 Control Module for ELR150 Series Power Supply

The CM150-08 is a control card that installs in an ELR150 Series Power Supply unit to drive one ELR device. It accepts a switch input (normally open contacts) or a voltage input of 5-24VDC or VAC, and delivers a 4.75 amp current pulse for up to 2 seconds to retract the device. After the input is removed, a user-selectable time delay of 0-4 minutes holds the output before the device re-latches. A dedicated fire alarm terminal provides immediate termination of output when a listed fire detecting device interrupts the circuit; a red LED (D3) blinks to indicate fire alarm activation. Relay-isolated auxiliary contacts (0.5 amp, 24VDC or VAC, normally open or normally closed) are available for remote signaling, such as a door operator signal.

Technical Specifications

  • Switch Input: Normally open contacts or 5-24V from a listed fire detecting device
  • Voltage Input: 5-24VDC or VAC; approx. 0.005 amp input current; minimum pulse width 0.25 seconds
  • Current Pulse Output: 4.75 amp (2 seconds max.)
  • Continuous Output: 3.6 VDC / 0.8 amp
  • Time Delay: User-selectable 0-4 minutes after input removal
  • Fire Alarm Terminal: Accepts normally closed contacts or 5-24V from a listed fire detecting device; red LED (D3) blinks on activation; provides immediate output termination
  • Auxiliary Contacts: Relay-isolated, rated 0.5 amp at 24VDC or VAC; normally open or normally closed; contact operation follows successful ELR device operation
  • Compatible Power Supply: ELR150 Series

Typical Applications

  • Commercial building access control with time-delay egress compliance
  • Healthcare and educational facility electronic locking
  • Government and multi-tenant residential access management
  • Emergency exit systems requiring fire alarm integration

BEST CM150-08 – Frequently Asked Questions

1) What does the BEST CM150-08 control module actually do in an ELR150 power supply?
The CM150-08 is a control card that installs inside an ELR150 Series power supply and drives one ELR (electric latch retraction) device. It takes a switch or voltage input, fires a 4.75 amp current pulse for up to 2 seconds to pull the latch back, then holds it at 3.6 VDC / 0.8 amp continuous. One card, one device: if you are retracting latches on a pair of doors you need a card per device.
2) What input voltage does the CM150-08 accept, and can I trigger it from an AC source?
Both AC and DC work. The voltage input on the CM150-08 accepts 5-24VDC or VAC at roughly 0.005 amp draw, so a card reader relay output, an access control panel output, or a low voltage transformer signal will all trigger it. Minimum pulse width is 0.25 seconds, so a very brief dry-contact blip may not register. There is also a normally open switch input if you would rather trigger from a plain contact closure.
3) Can I keep the latch retracted after the card read ends, for a delivery window or class change?
That is what the time delay is for. The CM150-08 has a user selectable delay of 0 to 4 minutes that starts after the input signal is removed, so a momentary card read or button press can hold the latch retracted for up to four minutes. Set it to 0 and the latch drops as soon as the input goes away.
4) How does the CM150-08 drop the latch on a fire alarm?
A dedicated fire alarm terminal handles it. The terminal accepts normally closed contacts or 5-24 volts from a listed fire detecting device, and when the alarm interrupts the circuit the module terminates output immediately, so the latch projects and the door relatches. A red LED (D3) on the card blinks while the fire alarm is interrupting, which is the first thing to look at when a door will not retract.
5) Can I signal a door operator so the automatic opener waits until the latch is pulled back?
Yes, and that is the intended use of the auxiliary contacts. The CM150-08 provides relay isolated contacts, wired normally open or normally closed, rated 0.5 amp at 24VDC or VAC. Contact operation follows successful operation of the ELR device, so the operator only gets its go-ahead once the latch has actually retracted. Keep the load inside 0.5 amp: this is a signaling contact, not a power feed for the operator motor.
6) Does the CM150-08 work as a standalone power supply for an electric latch retraction exit device?
No. The CM150-08 is a control card only, meant to be installed in a slot inside an ELR150 Series power supply. It has no power supply of its own, so you order it alongside or for an existing ELR150 unit, not instead of one. If you have no ELR150 cabinet on the job, the card by itself will not run anything.
7) My existing power supply is only rated a couple of amps continuous. Will it handle the CM150-08?
Look at the pulse, not the holding current. The CM150-08 draws a 4.75 amp pulse for up to 2 seconds to break the latch loose, then settles to 3.6 VDC / 0.8 amp continuous. The supply has to deliver that inrush per device or the latch will not pull, which is why the card is designed to sit in an ELR150 Series power supply rather than run off whatever low-amp transformer is already in the closet.
8) Is the CM150-08 module suitable for a school or hospital access control system, or is it a residential part?
It is a commercial part. The CM150-08 is classified commercial only and is built for electronic access control in buildings where a latch retraction device is tied to a card reader and a fire alarm, which covers schools, healthcare, government, industrial and multi-tenant work. The fire alarm terminal and the isolated auxiliary contact are the two features that make it a building-systems component rather than a light-duty one.
